    Jason is the General Manager at Mercedes-Benz of Walnut Creek. He knew the moment he first sat in a vehicle that he wanted to be a GM at a Mercedes-Benz dealership. No, not really... He actually wanted to be in a band and tour the world but we are lucky that he pursued his automotive career instead! Jason is dedicated to providing the best experience for our customers and our employees. In his free time, he likes to spend time with his beautiful wife Leah and their pups Oliver and Daisy Mae, hang out with family and friends, and eat lots of good food (mostly carbs).
