Born in Germany to Swiss parents, Walter Kienle trained as a tool and die maker until he immigrated to the U.S. from Switzerland in 1948. Here, he worked as an automotive mechanic in Redding, PA until he felt compelled to join the U.S. Army to serve his new country.

Stationed at Fort Irwin in Barstow, Walter quickly earned his stripes as the top student in tank school and was quickly promoted to Staff Sergeant. As a non-commissioned officer (NCO) he earned privileges at the Marc Air Force Base NCO Club in Riverside, CA where he was first introduced to the mild weather and friendly charm of Southern California.

Upon his Sergeant First Class discharge, Walter moved back to New York where he opened an automotive garage, married and started his family. Longing for that California sunshine, he returned to Riverside in 1960, and opened Walter's Automotive Service with an emphasis on European makes.

Although Walter Kienle has always demanded his people work to the highest standards, he treated them well and earned their respect and loyalty. Many have built long careers at Walter's with several 40+ year veterans still working at the dealership today.

With its trained technicians and reputation for excellent service, Porsche asked Walter's to become an authorized dealer in 1992 where it now enjoys the status of being one of the top Porsche dealers in the U.S. In 2004, the Audi line was added as a natural extension of Walter's fine line of German automobiles.
