    Mark Mauer

    General Manager

    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.

    Executive Manager

    With a passion for Porsche and a strong business background, I am excited to begin my new role at Porsche Arrowhead. A native of Scottsdale, I hold degrees in Accounting, Finance, and Entrepreneurial Business from Arizona State University’s W.P. Carey School of Business. My eight-year journey with the Porsche brand includes my prior position as Sales Manager at our sister dealership, Porsche Chandler. I am also currently in my second year of the elite Porsche International Dealer Academy, a two-year program at the University of St. Gallen in Switzerland that only 20 people worldwide are invited to attend.
    In my free time, I love driving my 2025 911 GTS t-hybrid, participating in Porsche Motorsports and Track Experience events, and staying active with friends and family.
