An ISTP woman names the mechanism, once, and stops. From a man that reads as authority. From her it reads as covering something — so the answer has to be proved again, physically, in front of whoever is doubting, and then proved again for the next person, and the one after that, for twenty-five years.
Arden Kosko stood in the control room at Cass Falls Community with her arms folded, looking at a picture of a plastic bottle, and said the problem was in the room and not in the magnet.
Marilee Batts, who ran imaging there, wanted to know what that meant.
“Your shield’s leaking.”
Marilee asked what would make it do that.
“Something’s not sealed.”
That is the entire explanation Arden gave, and it was correct. There was a penetration panel in the equipment room where a contractor had run a new conduit through for the fire alarm upgrade six weeks earlier and had not put the panel back the way panels go back, and the room was letting radio in, and the radio was writing a line across every image that scanner produced, and Cass Falls had been running patients through it for a month and a half and rescanning about one in six.
Marilee called our office an hour later and got me and asked whether I agreed with Arden.
I said I did.
She said she’d feel better if somebody came out and confirmed it. So I drove ninety minutes and stood in the same equipment room and looked at the same panel and said yes, it’s the panel, and Marilee thanked me twice, and we were paid for a second dispatch, and I was home by nine.
Arden came to Talcott Imaging Service in 2001. She was twenty-seven, out of a two-year electronics program and six years in a hospital biomedical department, which is where people who fix scanners generally come from. She is a medium-sized woman with short grey hair now who wears the same brand of boot she has worn since I met her. She does not fill silence. If you ask her a question she looks at the thing before she looks at you, and when she has an answer she gives it and then she is finished, and the finishing is what people notice. She carries her own tools in a case she rebuilt the foam for. In twenty-five years she never called our national tech line once, and the tech line has twice called her.
Talcott services magnets and scanners for community hospitals and imaging centers across a five-state footprint. Half of our buildings are places where the scanner is the single most expensive object anybody in that county owns, sitting in a room that was a storage closet in 1994, reached by a corridor that will not take the replacement unit when the day comes, which is a conversation every administrator has once and then postpones for eleven years. Fourteen engineers now, nine when I started. Ward Prentiss founded it in 1998 on the theory that a hospital would rather pay a person it knows than a manufacturer it doesn’t, and that theory was correct for about twenty years and is getting less correct every year. The manufacturers put diagnostics behind a login, then parts behind the diagnostics, then software behind the parts, and every one of those moves was defensible and every one of them took a little more of the room an independent can stand in. We compete against the people who built the machines. Our whole product is that we show up faster and we do not read from a script.
I have owned this company outright since 2016.
For twenty years I was the second signature on Arden Kosko’s work. Not her supervisor. Her peer, for most of it, and then her boss, and what I actually was, four or five times a month, was the man a customer called to hear the same thing again in a different voice.
Next week I am at Saint Anselm’s for a coverage handoff on their second magnet, which is going to the manufacturer on a full-service contract that I am not going to win back. The manufacturer’s engineer for this region is Arden Kosko. I have not been in a room with her since 2022.
Ward said it in a truck in about 2004 and I have said it since, to customers, to a lender, and once in a meeting about a promotion.
“She’s the best troubleshooter I’ve got and I can’t put her in front of a customer.”
Known Good
Every diagnostic trade runs on the same idea and this one has a name for it.
A known good is an object whose condition you are certain of, which you put into a system in order to learn about the system. In imaging it is a phantom — a sealed container of doped water or gel, machined to a spec, that scans the same way every time on a healthy machine. If the image of the phantom is wrong, the machine is wrong. If the image of the phantom is right and the patient images are wrong, the problem is somewhere else: the coil, the technologist, the protocol, the room.
Half of what an engineer does is deciding what to trust. The other half is that you can only find out about a thing you do not know by testing it against a thing you do.
The trouble is the intermittent. A fault that shows up on one scan in forty, at no fixed time, in no fixed place, leaves you nothing to hold. You cannot write a procedure for an intermittent. You cannot show it to a customer on demand, which means that for the entire period between the first complaint and the fix, the only thing standing between the hospital and a very expensive decision is whether they believe the person telling them what it is.
What a customer wants during an intermittent is a date. When will it be fixed. And the honest answer, most of the time, is that it will be fixed when somebody catches it in the act, and whether that is this week or three weeks from now is not a thing anybody can promise. Every engineer in this trade learns some way of saying that. The ones who do well learn a way of saying it that sounds like a plan.
Fern Salkeld has dispatched for us since 2004 and maintains the on-call board, which is a physical board, in the office, with magnets, because she tried the software twice and the software lost a weekend in 2015 and there will be no third attempt. Fern’s rule is that whoever takes the week between the holidays gets first pick of the following summer, and she has enforced this against two owners, including me, and she once let a hospital’s regional director hold for nine minutes because he was rude to her about a purchase order.
I coach a high school bowling team. We have never finished above sixth.
Demonstrations
She used to explain more. That has to come first here, because of what came after it.
In her first years she would walk a customer through it — here is the artifact, here is what makes that pattern, here is why it is not the coil. She stopped somewhere around 2006, and I did not notice her stopping, and I have worked out since that she stopped because it did not do anything. The explanation did not change what happened next. What happened next was always a phone call to the office.
What she moved to was better and worse. She started proving it.
At Belle Plaine in 2009 a chiller kept nuisance-tripping and the hospital’s facilities director was certain it was our machine drawing out of spec. Arden did not argue with him. She asked him to stand where he was, put a clamp meter on the leg he was pointing at, and had him watch the reading while she cycled the gradients on a phantom sequence, and the number went where she said it would go, and then she went out to the roof with him and put his hand on a contactor that was ninety degrees hotter than the two beside it.
He apologized to her. He apologized to me too, later, on the phone, which is its own thing.
That worked. It worked nearly every time. And it is not a career.
A demonstration is a one-off. It persuades the person standing there, that afternoon, and it does not travel, and it does not accumulate. There is no version of it you can put in a file. Every new imaging manager, every new facilities director, every new administrator at a hospital we had held for a decade — she started over. She proved it again. She proved it again in 2011 and 2014 and 2018 at the same building to three different people, and each of those people came away thinking she was terrific, and none of it added up to being believed the first time.
There is a number for what that cost, and it exists only because I went looking after the spring. Between 2009 and 2021 Arden logged more second visits than any engineer here by a wide margin. Each was coded as a customer-requested follow-up. Each was billed. So it never surfaced as a problem anywhere. It showed up as revenue.
Josiah Bly came to us in 2017 at twenty-four and Arden trained him for two years. He is good. He is not what she is, and he would tell you that. What Josiah does with a customer is give them the same explanation Arden gave them, in the same order, because she taught it to him, and then he says a sentence at the end that she never said, which is some version of and I’ll stay until we’re sure.
They love him. He has never once been asked for a second opinion.
Nine of the fourteen engineers here are men. That is better than the industry. Between 1999 and 2024 we put six people into a lead or account role. One was a woman and it was not Arden, and I know that because I made all six of those decisions and four of them I made without an interview.
I know exactly what that sentence at the end is doing. That sentence carries no information at all. It is a promise about the next few hours, and it turns out that a room of frightened people needs a promise about the next few hours before it can hear a word about a penetration panel. What the identical brevity buys a man in this trade — and it buys him plenty; we have a whole vocabulary for the quiet ones — gets its own accounting a page over.
I asked Arden, when he’d been out on his own a year, how he was doing.
“He’s good,” she said. “He tells them he’ll stay.”
I said that was something she could do too.
“I do stay,” she said.
The Second Signature
I need to describe the arrangement accurately because it was never once discussed.
A customer would call. They would ask, in some form, whether I agreed with what Arden had told them. I would say yes. Sometimes I would drive out. Sometimes I would say the identical sentence she had said, in the same words, and hear the customer relax through the phone.
The one I can still hear is from about 2015, a weekend call, an outpatient center whose administrator I had met twice.
“She’s saying it’s the cold head and that it’s a two-week part.”
I said that sounded right.
“So we’re down two weeks.”
I said we could look at a loaner arrangement and that in the meantime I’d have somebody take another look at it in the morning.
“Would you come?”
I said I would come.
I drove out there and stood next to Arden for forty minutes while she showed me a boil-off rate she had already documented two days earlier and a helium level trend she had already put in the report I had already read, and then I called him from the parking lot and told him it was the cold head and that it was a two-week part.
He thanked me for coming out on a weekend. There was no sarcasm in it. He was relieved, and his relief was real, and I billed him for the visit.
That is thousands of small transactions over twenty years and every single one of them was me doing her a favor. That is how it felt to me at the time and I think that is how it felt to her, and it is the reason neither of us ever said anything about it, because you do not have a difficult conversation about a favor.
What it actually did was confirm, four or five times a month, for two decades, in front of the customer, that her call required confirming.
Ward and I talked about her for a lead position in 2008 and I said she’d hate the customer side of it, and Ward said she’d hate the paperwork more. Both were true. Neither was the reason, and the reason went unsaid in that truck the way it went unsaid everywhere else.
I asked her about it exactly once, in 2013, in a hospital lot in a town that will not be named here, because of what she said.
“Does it bother you when they call me after?”
She thought about it. She actually thought about it, which I had not expected.
“It costs the customer four hundred dollars,” she said.
Rocklin
That account was ours for nine years and we lost it in a single phone call in 2016.
Their magnet had an intermittent. About one exam in thirty came out with a wrap artifact that had no business being there, and it moved, and it did not correlate with the coil or the sequence or the technologist, and Arden had been on it three times in five weeks.
She told them it was a bad ground on the RF cabinet and that the fault was mechanical — a lug that made contact when the room was cold and lost it as the day warmed, which is why the mornings were clean.
That is a real thing and it was the right answer.
Their imaging manager was new, four months in, and had a director above him who had been told by an OEM salesman named Chad Vandiver that independents were a false economy. He called our office and asked me whether I agreed with Arden’s diagnosis.
Here is what I said. I have had ten years to work out a better version and there is not one.
“I wouldn’t want to commit to that without eyes on it.”
It is a professional sentence. It is a careful sentence. It is what you say when you have not personally been in the room and you do not want to guarantee a hospital something you cannot see. Every word of it is defensible and I would have said the same about Josiah and I do not know whether that is true.
They had the manufacturer in the following week. The manufacturer’s engineer found a bad ground on the RF cabinet. Rocklin signed a full-service contract with the OEM ninety days later and we have not been back in that building.
I raised it with her, once, badly, about a month later, in the shop, standing between two benches.
I said I hoped she knew that I’d never had any doubt about the call.
“I know,” she said.
I said that with a new manager and a director involved, sometimes you have to give them a process.
She put down what she was holding, which she does when she is about to be finished with a conversation.
“Perry, do you want me to say it’s fine?”
I said no.
“It’s fine,” she said, and picked it back up.
Arden never raised it with me again. That is the part I keep going back to. There was no confrontation and no cold spell. She kept working, and about six weeks later I heard her on the phone with a different hospital, and what she said was, “I can tell you what it is, but you’re going to want Perry to say it, so let me have him call you.” She said it pleasantly. She was being helpful. She had absorbed the whole architecture and turned it into a service she now offered.
I let her do that for six years and never once corrected it. I told myself it was efficient.
She gave notice in 2022. She was forty-eight. She went to the manufacturer — the same one, not the same salesman — as a regional service engineer, at more money and a company car and, she told Fern, a badge that gets her into buildings without anybody deciding whether to let her in.
At her last lunch I made a speech about how she had forgotten more than the rest of us know, which is a compliment I have heard men give women in this trade my whole life and which I did not hear myself saying until about a year ago.
Fern told me afterward that Arden had asked her to keep it short.
“Short how?”
“She said, tell him no speech,” Fern said. “I forgot.”
The Recording
We record dispatch and escalation calls. Every service organization does. It is for quality and for the insurance and nobody listens to any of them.
Last spring, doing the coverage analysis for the Saint Anselm’s renewal, I needed the Rocklin file for the loss history and I found out the audio was still on the server. All of it. Nine years of it.
I listened to the 2016 escalation call at my desk with the door shut.
I have carried a version of that call in my head for a decade and my version has me being reasonable and slightly rueful. What is on the recording is that the imaging manager asks me twice, and the second time he tells me the director wants a name on it, and I say my sentence, and then — this is the part I did not have — I say, “Arden’s very good on the hardware side.” Which is a compliment. Which, said in answer to will you put your name on this, is not a compliment.
Then I went back to the front of the call, which I had never heard, because the escalation call includes the conference-in.
She is on it for six minutes.
She explains the whole thing. The artifact, the pattern, why it moves, why the mornings are clean, the thermal expansion at the lug, what she wants to do and how long it will take and what it will cost if she is wrong. In order. In complete sentences. It is a better explanation than I could give today with the transcript in front of me.
Then the imaging manager says, “Okay, so — I guess my question is, are we sure?”
And she says, “I’m sure.”
And he says he’ll call the office.
The Card
Our benefits broker did a half-day session at the shop in 2013 as a renewal sweetener. Team communication. Sandwiches. Twenty-two of us in the break room with the good chairs brought in from the conference room.
Everybody got a laminated card, wallet size, with the sixteen boxes on the front and a short paragraph for each, and the broker’s logo and an eight-hundred number on the back. There was a follow-on product they were selling and we did not buy it.
Arden’s card was in her truck when we bought the truck back from her in 2022. It was in the door pocket with a tire gauge and a parking pass from a hospital that closed in 2019. I left it where it was at the time. I went and got it after the recording.
She had written on the back of it, in pencil, in the small squared-off hand she uses on service reports.
The front of the card says ISTP and then: practical, analytical, adaptable, enjoys solving problems, may prefer action to discussion. She had drawn a line from enjoys solving problems into the white space and written: Everybody enjoys solving problems. What I can’t do is use a thing I don’t understand.
That is the top of the sequence in twelve words, and the card had missed it entirely. What sits up there is a working model of the mechanism — assembled by pulling the thing apart, held privately, and answering to nothing on earth except whether the object behaves the way the model says it will. Which is why she never called the tech line. The tech line has the manufacturer’s model. She had her own and hers was better.
Next to may prefer action to discussion she wrote: Not action. Contact. Can’t do it from the office.
Which is the second one, and it is the whole reason the demonstrations happened. The model does not run in the abstract. It comes fully on when she is in the room with the thing — hand on the cabinet, phantom in the bore, meter on the leg. That is why she got Belle Plaine’s facilities director to hold the clamp himself. There was no performance in it. She was doing the only thing she does and letting him stand inside the middle of it.
At the bottom of the card, in the margin under all sixteen boxes, she had written 1 and 2 next to two of the items on her own list, and then, further down, one word: bottom, with a bracket around two more. Which of them sits where in that order gets worked out in the piece on this type, drawn from the sixteen the card was printing badly.
The two she bracketed at the bottom are the temperature of a room full of people, and the long shape of a thing over years. She knew. That is what undid me about the card, and It has sat in my desk since the spring. Nobody told her. She took a marketing giveaway apart in a truck at some point in the last ten years and arrived at an accurate account of her own construction, including the parts that were costing her, and then she put it back in the door pocket with the tire gauge.
I want to put down one thing plainly, and I am the wrong person to say it, which is why it should be said by me. If the same call gets checked when one person makes it and does not get checked when another person makes it, that is a pattern, and a pattern can be counted — we had the dispatch log the whole time and I could have run it in an afternoon in any year of the last twenty. And if a customer asks for a different engineer and the reason is what the reason usually is, the company has a problem with a name on it and there are people whose job that is: a lawyer, an HR office, whoever your organization has for it. A laminated card from a benefits broker belongs nowhere in that conversation and will not do the work of one.
The broker’s card says, in type you need light for, that the questionnaire is a conversation aid and not a hiring or assignment tool, and that a second pass a month later leaves about a third of people sorted into a different box, while the measures underneath it move much less.
I read that in 2013 and I remember thinking it was a nice free lunch.
Saint Anselm’s
She has the region for the manufacturer now, which means she covers every hospital I have, and next week we are both at Saint Anselm’s for the coverage handoff on the second magnet, which they are moving to the OEM contract and which I will not be winning back.
I have thought about what to say to her and discarded all of it. Every version is either an apology she did not ask for or a job offer I cannot fund, and she will hear whichever one it is inside four words and then wait, politely, for me to finish.
Listening to that recording reversed two things I had been certain of, and neither was the one I had gone in for.
Cass Falls, first, and your shield’s leaking, something’s not sealed. I have told that story for years as a demonstration of how little she would give a customer. Six words and a ninety-minute drive. What I hear now is that she had already run the phantom, which is on the bill, and the phantom was clean, which eliminated the magnet and the coil and the sequence in one move, and the problem is in the room was not a hunch withheld from us. The test was already behind that sentence and the test was in her hand, and nobody asked her what she had scanned.
Then the parking lot in 2013 and it costs the customer four hundred dollars. For years I filed that as the driest joke she ever made. She was not being dry. I had asked her a question about her feelings and she had answered the question that had an answer, and the answer was the only part of the arrangement that could be measured, and she gave me the number, and I laughed.
The things the card had no room for. She will not be spoken to while she is working inside a machine, and the one time a facilities man put his hand on a cabinet with her arm in the bore she said something to him in front of his own director that will not be repeated here; she has a brother she supports and has supported since 2007 and I learned this from Fern; and she stood up at Ward Prentiss’s funeral in 2021 and talked for six minutes without a note, warmly, in front of two hundred people, and afterward three of our own engineers said they had never heard her like that, and I have no idea what to do with that and it does not fit anything else here.
Josiah is coming with me to Saint Anselm’s. He asked whether it would be weird.
I said it would be fine. Then I told him to watch what she does before she says anything, because that is the part worth having, and he said okay, and I could hear that he thought I was being sentimental about an old colleague.
The people in these essays are composites drawn from long observation. The theory is not.
