Career Change to Investment Banking at 40

Fourteen years as a controller. What made you want banking?

Boredom is the honest answer. I was the controller at a mid-size manufacturing company in the Cincinnati suburbs. $400 million in revenue. We made automotive parts. I ran a team of 8 accountants and finance people. I did the monthly close, the quarterly reporting, the annual audit, the budget cycle. I was good at it. I made $145,000 and I'd been making around that number, adjusted up a few percent each year, for about six years. The ceiling was visible. The job above me was CFO, and our CFO, a man named Boyd, had been in the role for nine years and showed no signs of leaving.

Banking interested me because I wanted to work on transactions. I'd been on the other side of two acquisitions during my time as controller. Our company acquired a smaller parts manufacturer in 2019 and a distributor in 2021. Both times, bankers came in, and they were smart and they understood the business quickly and they ran the process. I was the person providing the financial data, answering the diligence questions, populating the data room. And I kept thinking: I could do what they're doing. I know the numbers better than they do. I just don't know how to package them.

So you went to Kellogg at 39.

Part-time program. My wife Rosalind and I ran the numbers. Full-time MBA meant quitting, losing $145,000 in salary for two years, plus tuition. The total cost would have been about $450,000 when you count the foregone income. We have two kids, Josie and Marcus Jr. (he's 8). A mortgage. We couldn't do that. The part-time program at Kellogg costs about $215,000 in tuition over two years. I kept my salary. I commuted to Evanston every other weekend for classes. Rosalind handled the kids on those weekends. She's a middle school science teacher. She makes $62,000. She was, effectively, subsidizing my career change with her time and energy. We talked about that explicitly. She said, "Go. But this better work."

The MBA cohort skewed young. Average age was probably 30. I was 39 when I started, 41 when I graduated. There was one other person over 35. Most of the students were targeting consulting or tech. Maybe six of us were targeting banking. Of those six, I was the oldest by about eight years. During recruiting, I went through the same process as everyone else: resume drops, first-round interviews, superdays. The difference is that the interviewers looked at my resume and saw "controller, 14 years" and they had to figure out what to do with that. At a bulge bracket, they passed. Two bulge brackets dinged me before the superday. A third gave me a superday and then dinged me. The feedback was indirect but clear: they wanted analysts and associates who would grind for two years and leave. A 41-year-old with a family and a mortgage is not going to grind and leave. He's going to want to stay and progress, and that disrupts the pipeline.

Who said yes?

A middle-market bank in Cincinnati. The same city I already lived in. They have about 60 people and they cover industrials and business services. The MD who interviewed me, a woman named Trish, spent 20 minutes asking about the acquisitions I'd worked on as controller. She wanted to know what I'd seen on the other side. What data did the bankers ask for? What did the management team get wrong about valuation? What surprised me about the process? I answered everything from 14 years of being in the room. She offered me the job two weeks later. Associate level. Base: $150,000. Bonus target: 60 to 80% of base. First-year total comp: about $240,000.

That's more than you were making as controller.

Yes, but net of the MBA cost, it's not. I spent $215,000 on tuition. Kellogg doesn't come cheap. My salary during the MBA didn't change, so I didn't lose income, but I spent $215,000 that I would not have spent otherwise. To recoup that, I need the incremental income from banking versus my controller salary to exceed $215,000 over some reasonable timeframe. The delta is about $95,000 a year ($240,000 versus $145,000). So the payback period is about 2.3 years if the income holds. But the income is not guaranteed. The bonus is discretionary. And if I'd been promoted to CFO at my old company, which was unlikely but possible, the gap would be smaller. Rosalind and I agreed to evaluate at the three-year mark. We're at year two. So far the math is working.

What transferred from 14 years as a controller?

The financial fluency. Massively. When I open a company's financial statements, I know what I'm looking at in a way that someone who learned accounting in a textbook does not. I can spot inconsistencies in a balance sheet by feel. Revenue recognition issues, working capital anomalies, weird depreciation schedules. I've lived inside those numbers for 14 years. On the last deal I worked, a $120 million sell-side for a specialty chemical distributor, I was reviewing the target's financial data in the data room and I noticed that their inventory turns had deteriorated from 8x to 5.2x over two years but their gross margin had stayed flat. That combination usually means they're building inventory they can't sell, or they're capitalizing costs they should be expensing. I flagged it for Trish. We dug in. It turned out they'd changed their inventory costing methodology from LIFO to FIFO without restating the prior periods. The gross margin stability was an artifact of the methodology change, not actual performance. If we'd presented those margins to buyers without the context, the valuation would have been overstated by about $8 million.

A 25-year-old analyst would not have caught that. Not because they're not smart. Because they haven't sat inside an inventory costing decision for 14 years. That's what I bring. The pattern recognition.

What didn't transfer?

Speed. The pace is different. As a controller, I had monthly deadlines and annual cycles. The work was predictable. In banking, a VP sends you a message at 3 PM and the deliverable is due by morning. I'm not as fast as the 26-year-old analysts because I haven't been trained in the sprint culture. I build better models but I build them slower. My formatting is worse because I never had to make PowerPoint presentations that would be judged by a managing director with opinions about chart margins. I spent my first three months learning the firm's template library. Three months. On PowerPoint templates. I could build you a five-year integrated financial model with a sensitivity analysis in my sleep. Aligning text boxes in PowerPoint to within a millimeter took me 90 days.

The other thing that didn't transfer is the physical stamina. I'm 43. When I was a controller, I worked 8 to 5:30. Maybe 6 during close week. Now I routinely work until 9 or 10 PM. Once a quarter or so, there's a late night until midnight or 1 AM. My body does not respond to that the way a 25-year-old's body does. I drink more coffee. I sleep worse. My right shoulder has a thing now that it didn't have before, from the mouse and the second monitor. Rosalind bought me an ergonomic keyboard for Christmas. It helped. The metaphor of your body keeping score is not a metaphor.

What's yours?

The title. I'm an associate. The person sitting next to me in the bullpen is also an associate. She's 27. We have the same title. She reports to the same VP. She was promoted from analyst last year. I was a corporate controller who managed eight people and reported to the CFO of a $400 million company. Now I have the same title as someone who graduated college five years ago.

That sounds petty and I know it's petty. But the title reset is the thing that nobody prepares you for. When I was controller, vendors called me "sir." The audit team from the Big Four firm called me by my first name and deferred to my judgment. Now Trish gives me notes on my formatting. My VP, a very capable 34-year-old named Ramona, marks up my models with red comments. She's right most of the time. That's not the point. The point is that I went from being a senior person in a room to being a junior person in a different room, and the adjustment is not intellectual. It's emotional. Marcus Jr. asked me once, "Dad, are you the boss at your new job?" I said, "No, buddy. I'm learning." He said, "Like at school?" I said, "Yeah. Like at school." He accepted that more easily than I have.

How does a management consultant end up in investment banking without an MBA?

Relationships. That's the entire answer. I was a principal at a Big Four consulting firm for 15 years. My practice area was government services and defense, meaning I advised companies that sell products and services to the federal government. Think cybersecurity firms, IT services companies, defense contractors in the $100M to $1B range. Over 15 years, I built relationships with the CEOs and CFOs of about 30 of these companies. I knew their businesses. I knew their financials. I knew their growth strategies because I'd helped them build the growth strategies.

In 2023, one of my clients sold his company. The advisory firm that ran the deal was a D.C.-based boutique that specializes in government services M&A. After the deal closed, the boutique's managing director, a guy named Harrison, called me. He said, "You know every CEO in our target market. You've done the operational diligence on half the companies we cover. Would you consider joining us?" I thought he was joking. He wasn't. He offered me a VP role. No MBA required. The value I brought was the rolodex and the domain expertise. The financial modeling, the deal mechanics, that's teachable. The 15 years of relationships are not.

What was the pay change?

I was making $230,000 total at the consulting firm. Base of $190,000 plus performance bonus. Harrison offered me $200,000 base with a bonus target of 75 to 100% of base. First-year total comp was $340,000. So I took a small base pay increase and a significant total comp increase. That's unusual for a career change into banking. Most people take a pay cut. I didn't because I wasn't starting from scratch. I came in at VP level because my experience warranted it. Harrison didn't hire me to train me. He hired me to bring clients.

Noemi and I don't have kids. We own a condo in Dupont Circle. Her documentary work is project-based, so her income is variable, maybe $45,000 to $75,000 a year depending on what's funding. Having no kids and a relatively low mortgage meant the financial risk of switching was manageable. If we'd had two kids and a house in McLean, I'm not sure I would have made the same decision. The risk tolerance changes when there are school tuitions involved.

What does your consulting background give you that traditional bankers don't have?

Two things. First, I can talk to CEOs as a peer, not as a service provider. When I sit down with the CEO of a government IT company, I'm not cold-pitching. I've probably met them before. I may have worked with their competitors. I understand their industry in a way that a generalist banker does not. I know what a GWAC contract is. I know what an IDIQ vehicle looks like. I know the difference between cost-plus and firm-fixed-price and why it matters for valuation. That language is the key. When Harrison and I pitch a company, I do the industry portion and he does the deal process portion. We're both credible in our lane.

The second thing is the operating perspective. In consulting, I sat inside these companies for months at a time. I know how they actually run, not just how their financials represent them. When I read a management presentation that says "we have a diversified customer base," I can push back and say, "Actually, 40% of your revenue comes from three programs at the DoD, and those programs are up for recompete in 2027." That level of specificity changes the conversation. Buyers trust my diligence because it's grounded in operational reality, not just financial analysis.

What's harder than you expected?

The pace of the deliverables and the precision required. In consulting, a deck can be directionally correct. If a market size estimate is off by 15%, nobody's making a $200 million decision based on it. In banking, every number in a model flows through to a valuation that a buyer will use to write a check. If the EBITDA adjustment is off by $500,000, the enterprise value is off by $3.5 to $5 million. The margin for error is radically different. I spent my first six months learning how to be precise in a way that consulting never required.

My analyst, Kai, taught me more about financial modeling than my MBA-educated colleagues would probably be comfortable admitting. Kai is 24. He was patient with me in a way that I found both generous and humbling. He'd sit next to me and say, "The WACC formula references the wrong cell. Here, this one." He never made me feel stupid. But I felt stupid sometimes. The feeling of being 41 and having a 24-year-old correct your Excel formula is specific. It's not bad. It's just very specific. Noemi calls it "beginner's mind." I call it "my face gets hot and I fix the formula."

In consulting you traveled constantly. How does banking compare?

Better, actually. In consulting I was on a plane every Monday morning and home every Thursday night. Four days a week at a client site, usually in a different city. Over 15 years I estimate I spent about 3,000 nights in hotels. In banking, most of my work is in the office or on Zoom. I travel for pitches and client meetings, maybe two or three trips a month, usually day trips to Baltimore or northern Virginia. The rest of the time I'm at a desk. The hours are longer than consulting on average, but the travel is dramatically less. My body appreciated it immediately. I stopped getting those dull headaches you get from recycled airplane air. Noemi appreciated it more. She said, "I forgot what it's like to eat dinner with you on a Tuesday."

What's yours?

How the consulting part of my brain sometimes fights the banking part. In consulting, my job was to be objective. Analyze the problem, present options, let the client decide. In banking, I'm an advocate. My job is to get the best outcome for my client, which usually means the highest price. Those are fundamentally different orientations. When I'm reviewing a company's financials for a sell-side engagement, there's a moment where the consultant in me wants to flag every weakness, every risk, every thing a buyer should know. But the banker in me knows that my job is to present the company in the best honest light. Not dishonest. But best. There's a version of the story that emphasizes the growth trajectory and a version that emphasizes the customer concentration risk. Both are true. My job is to tell the first version and let the buyer's diligence team find the second.

That orientation shift took me about a year. Harrison noticed it early. He said, "You're writing like an auditor. You need to write like a salesperson." He wasn't criticizing. He was naming the exact tension. I came from a world where objectivity was the product. I moved to a world where advocacy is the product. Both are legitimate professional orientations. The transition between them is not seamless, and nobody warned me about it, and some mornings I still catch myself writing a management presentation that is too balanced and I have to go back and sharpen the narrative. "Sharpen the narrative" is banking language for "emphasize the good parts." I do it. It's fine. It's just different from what I was trained to do for 15 years.
