Mark Mauer
General Manager
About
Originally from Council Bluffs, Iowa, I moved to Arizona drawn by the spirit and landscape of the Southwest. With more than three decades in the automotive industry, beginning in 1992 as a salesperson, I have built my career on performance, accountability, and an unwavering commitment to exceeding customer expectations. At Porsche Arrowhead, my priority is leading a team that delivers excellence at every level. I believe true performance comes from disciplined processes, empowered people, and a culture that goes beyond what’s expected is the standard, not the exception. Every interaction should reflect the precision, craftsmanship, and emotional connection that define the Porsche experience. Outside the dealership, I value time with my wife, grandchildren, family, friends, and our loyal four-legged companions. I’m an avid mountain biker and racer, outdoor enthusiast, and firm believer that pushing personal limits on the trail or in daily life builds the focus and resilience needed to lead high-performing teams.
