Bryan Loser

Bryan Loser | Parts Manager

I started in the auto business in 1986 as a parts driver and worked my way up to the parts manager.   I worked with the domestic brands until November of 2010 when I joined the International Autos group.  I became a Porsche certified parts manager in 2011 and have recertified each year since.  I enjoy helping our guests when they come to shop or have repair work done.  Please feel free to contact me with any questions you may have and I look forward to meeting you.
