Stephanie Corbin spent more than 25 years in corporate IT, then helped build Bullet Automotive and Diesel from a simple idea sketched on a Chick fil A napkin into a growing multi location operation on Colorado's Front Range.

In this episode, Stephanie breaks down what it takes to scale without losing the thing customers actually care about, trust. She shares the four pillars Bullet is built on, honesty, integrity, reliability, and transparency, plus how those values turn into real systems inside the shop. You will hear how they designed vehicle inspections, how they write recommendations, and how they quote and explain work so customers understand what they are paying for and why.

If you are trying to grow beyond one location, tighten your process, or build a shop that wins on clarity instead of hype, Stephanie's story will give you practical ideas you can use.

Ken Stafford spent decades in the collision world, sold his business, and tried retirement. It did not stick. What started as a small "keep busy" shop quickly turned into something bigger, especially once Chris Oatman came in and Ken handed him the keys to run day to day.

In this episode, Ken and Chris unpack how Next Auto Care in Highlands Ranch, Colorado grew from a side operation into a real business with a real team. They talk about what it takes to scale without losing quality, including hiring with culture in mind, creating trust through consistency, and adding layers of support that most shops skip.

You will also hear the "next level service" details that customers actually notice, like mini detail touches after the repair, plus a dedicated quality control role to help prevent comebacks and protect the customer experience.

If you want a clearer picture of how to grow steadily, stay people first, and build a shop where customers and employees want to stick around, this one is worth your time.

Collin Ettienne built RI Automotive in Tampa the hard way, starting with one lift in a storage unit, wrenching nights and weekends, and (for a season) balancing the shop while working as a firefighter.

But the real turning point wasn't opening the doors, it was having the guts to reinvent the business.

For years, RI was heavily performance-focused: big builds, fast parts, fun projects… and brutal cash flow. In this episode, Collin breaks down the pivot he made after getting around other operators and training environments, shifting toward a sustainable general repair model that could support a team, systems, and long-term growth.

You'll hear Collin get honest about what made the change hard: ego, the need to be "the guy," and learning how to lead without doing everything himself. He also shares what they've put in place to build real A-players; training rhythms, team communication, and using tools like DVIs to drive clarity and trust.

If you're stuck in "busy-but-chaotic," or you've built a shop around what's exciting instead of what's scalable, Collin's story will hit home.

Preston Callahan's shop story starts the way a lot of real ones do: wrenching at 16 in the shade of a tree in front of his parents' house, then making the leap to ownership at 23, working out of the driveway and betting on himself.

Today, Preston runs Callahan Auto & Diesel in downtown Mesa, Arizona, plus a separate arm focused on 24-hour emergency roadside service for trucks and RVs. In this interview, Preston walks through what it actually took to grow, moving from a small 1,850 sq. ft. space to a facility of 10,000+ sq. ft.—and the lessons that only show up once you're responsible for payroll, margins, and the "everything breaks at once" reality of running a shop.

You'll hear him get candid about the mistakes that happen when you don't know your numbers fast enough, the constant balancing act between parts margin, labor margin, and staffing, and why even years in, he's still experimenting and learning (including what he calls his "Google business degree").

Erik Rud built Big Thompson Diesel & Automotive in Loveland, Colorado by doing the opposite of what he saw in too many shops: rushing work, chasing clock-time, and treating people like numbers.

In this episode, Erik breaks down how he went from frustrated employee to trusted problem-solver and why his shop has become a go-to destination for diesel and diagnostic work that other places can't quite nail down. He talks candidly about building a culture that prioritizes fixing it right the first time, why he pays his techs hourly with profit-based bonuses (not flat rate), and why he keeps his "foot on the brake" with growth to protect quality.

You'll also hear Erik's perspective on the training gap in our industry, what's broken, what techs actually need, and what he's doing to develop people instead of constantly shopping for unicorn hires.

If hiring feels like a fire drill this one is your reset.

In this Expert Spotlight episode, David sits down with Chris Lawson, founder of Technician Find, to break down what actually works when you're trying to hire great techs (and why most shops keep losing candidates even when the pay is solid).

Chris walks through the recruiting framework he's used with shops across the country:

• How to create a consistent flow of applications (and why you "can't optimize zero")

• Why most technician ads look identical and how to write ads that stand out and convert

• The reality that only about 1 in 4 applicants will be qualified and how to filter fast

• The backend mistakes that cause ghosting (slow follow-up, weak rapport, messy process) and how to tighten your systems + offer so good candidates don't slip through the cracks

• Why speed-to-lead matters more than most owners think because top techs are talking to multiple shops at once

If you want a real hiring system instead of another "post-and-pray" cycle, this episode will give you a playbook you can implement immediately.

Steve Mancinelli is a third-generation shop owner who's spent more than half a century in the automotive industry and he's still pushing his team to stay ahead of where the market is going.

Steve runs Mancinelli's Auto Repair Center in downtown Denver, a family shop that's operated out of the same location since 1950. In this episode, Steve shares how a shop with deep roots avoids getting stuck in the past, by combining old-school relationship service with modern execution: thorough digital inspections, factory-level tooling, and a serious commitment to ongoing training (including 60+ hours per tech each year).

You'll also hear Steve's personal turning point, he originally considered becoming a doctor, but realized he couldn't separate the emotion from the work. Instead, he brought that same care into the bays and built a reputation for solving the vehicles other places can't, especially late-model European and electrified (hybrid/EV) platforms.

If you want a real look at what "staying relevant" actually means for independent shops, without losing the human side, this episode is packed with perspective.

Darrell Weddell is the kind of operator who doesn't chase hype, he builds the business brick by brick.

🚗 https://hinsdaleauto.com/

In this episode, Darrell shares how he took a struggling Hinsdale Automotive in Littleton, Colorado and steadily turned it into a 7-figure shop known for honest diagnostics, clear communication, and top-quality work on both gas and diesel.

You'll also hear Darrell get practical about what actually matters at the growth stage: building systems knowledge, tightening your process, making smarter marketing decisions, and approaching hiring like a long-term investment, not a panic move. If you're trying to scale without losing your standards (or your sanity), this one delivers.

Corry Brown didn't stumble into leadership, he earned it the old-school way: starting at the bottom, getting coached by strong mentors, and stacking reps until he knew how a great shop should actually run.

Now Corry is the co-owner of McCormick Automotive Center and McCormick Quality Tires & Lube in Fort Collins, Colorado, operating two different business models under one roof of standards, a full-service AAA-approved repair shop and a quick-service tire/lube store just minutes away.

https://www.mac1auto.com/

In this episode, Corry gets extremely practical about the real problem most shop owners are facing: finding and developing technicians who want a career, not a job. He breaks down the structured system he built to create a pipeline: including GS-level progression, hourly-to-performance pay, tool support, and bonuses that reward senior techs for training the next generation. He also shares why he hires for attitude + punctuality, how he thinks about controlling comebacks, and what it takes to build a team that takes pride in doing it right.

If you're tired of hiring roulette and want a repeatable way to grow talent inside your shop, this one will give you ideas you can actually use.
