"I began my career at a Goodyear Tire Center in 1997 as I was going through Automotive training at Automotive Training Center in Exton, Pa. After graduating, Audi offered me a 6-month specific course to become a registered Audi Technician. I worked my way up to Master Guild status in 2005 and worked as a Technician until 2012, at that point I had the opportunity to take over as the Service Manager for Audi Devon. I have been married since 2005 and have one daughter (Thankfully she takes after my wife). I enjoy working on cars and motorcycles. My passion is riding motorcycles on the street and track."

United State Marine Corps Veteran

"From a young age, I always liked to tinker and take things apart. As a teenager, that turned into working on cars. At 20, I enlisted in the United States Marine Corps where I served 4 years as a M1A1 Abrams Tank Technician. Upon receiving my discharge, I used the G.I. Bill to go to Universal Technical Institute where I took courses for Automotive Technology and Ford FACT (Factory Authorized Credential Training). After graduating, I worked as a technician at a Ford dealer, a limousine and transportation company, until I found my home here at Audi Devon. In my free time, I enjoy working on my project vehicles, riding motorcycles, four wheeling and playing with my dog."

Audi Specialist Service Technician Certified

My name is Matt Stone, and I'm originally from Denver, Colorado. I moved to PA in 2004. I started my career in 1999 at an independent import shop where many of my early skills were forged. Then in 2004 I progressed into Volkswagen. In 2011 I left VW seeking more of a challenge, which I found in Audi. It has been a truly fulfilling transition. My passions include my beautiful wife and son, "the great outdoors", mountain bikes, all things German, and science and technology. My dream is to one day become a physics engineer, which my studies are already underway.
