When it comes to discussing the people of Downtown Porsche, the team and the customers, Chris radiates with pride. “There’s a lot of enthusiasm on both sides.” The most important strength Chris believes he brings to the team is keeping the energy high amongst team members. While Chris isn’t overseeing engaging dealer events and interactions, he spends his time playing guitar in a rock band, motorcycling, skiing and travelling the world. He has been privileged to drive some of the World’s greatest roads – Hwy 1 San Francisco to LA, the Simplon pass in Switzerland, the Passo dello Dolomiti in Italy, Lugano to St. Moritz, and the Stelvio pass from Italy to Switzerland.
