The Power of Taking Action on Personal Branding & Investing in Yourself (Interview with David Marks)

Adam McChesney Episode 177

In over 175 episodes since launching this podcast, I’ve never had a repeat guest, until now.

I’m excited to welcome back David Marks.

David and I met in 2020, when I created a local STL Facebook group to support businesses during Covid — while I was still in medical device sales. He was one of the first people I interviewed. That video is still floating around YouTube, and it’s wild to see how far we’ve come.

Since then, he’s supported me nonstop. He attended my first business event in 2021, was member #1 when we launched BOA in 2023, and has been a 1-1 coaching client and mastermind member.

Last year, I had him on the podcast and it was a great episode.

A few weeks ago, he asked to come back and share his firsthand BOA journey. I immediately said yes.

David is the perfect example of what we teach at BOA, and I’m grateful he’s sharing his story.

David’s Bio:

My entrepreneurial story starts in Sep 2008 when I bought a “Garage With A House In The Front Yard.” In Dec 2009, I began working part-time, and by May 2011, what started with ZERO customers became a full-time business.

In 2013, I added Used Auto Sales — people liked buying cars from a trusted technician. In 2016, I joined SCORE & the SBDC to learn how to become a true business owner. (Anyone can be a backyard mechanic — not everyone is a business owner.)

In 2018, I launched Used Car Detective to inspect vehicles before purchase. By March 2019, I expanded to a 3-bay full-service facility in Maryland Heights, which allowed me to grow all three businesses: Quality Auto Repair And Tire, Quality Auto Sales, and Used Car Detective.

To manage it all, I created DSM Auto Family, LLC.

My businesses continue to grow with one core belief:
People won’t work with you if they don’t feel appreciated. We live that out by providing trusted service every day.
