My career in automotive sales began with a less-than-ideal car-buying experience of my own — and I’ve spent the last 25 years making sure no one else ever has that same feeling.
I cut my teeth in 1999 at Cypress Coast Nissan/Subaru in Seaside, California, where I quickly became the #1 salesperson. In 2000 I fell in love with German engineering and joined Volkswagen Auto Group. I built my first Internet Sales Department, became Fleet Manager, and by 2002 ranked #1 out of 512 salespeople in VW’s Area 43. That success took me to Mercedes-Benz of San Francisco (where I started yet another Internet Department and again earned top-sales honors) and eventually to Colorado in 2005.
Over the next 15 years I proudly represented Mercedes-Benz and Audi, creating three Internet Departments from the ground up, winning countless sales awards, and earning factory invitations most only dream of: the Master Guild Tour and AMG factory visit in Germany, the Black Forest Alps Rally, the Audi e-tron launch in Munich, the Q7 launch in Austin, and top rankings in both brands across Colorado and the Western Region.
When COVID-19 hit in March 2020, everything changed overnight. After being furloughed from Audi Flatirons, I became the very first associate called back. I wrote our entire touchless-delivery template library and personally sold 52 vehicles in 52 days while the world was still locked down.
That same summer, like so many Americans, my family needed an escape. We bought a 2020 Renegade Verona from Transwest RV — and ten days later I was working here. I launched my #RVsInsideOut video walk-around series (giving customers the transparent, no-surprises experience I always wished I’d had), and the program took off, and the rest is history.
In five short years at Transwest I’ve become one of the top-performing RV specialists in the country, traveling to factories (Newmar, Renegade, Winnebago, Freightliner), leading our local Newmar chapter on unforgettable rallies, and helping hundreds of families find their perfect coach.
Whether you’re looking for your first RV, trading up to a luxury diesel pusher, or adding the perfect trailer or truck to your lineup, I’d love to put my quarter-century of award-winning sales experience to work for you — the same way I do for every client: honest, transparent, and 100 % focused on making this the easiest (and most fun) vehicle purchase you’ve ever made.
Your slightly obsessed, award-winning, tell-it-like-it-is RV matchmaker
