I had frank care for my three Toyota's and just got a 2015 Dodge Ram 3500 4x4 diesel turbo. He now does all my service unless it's a warranty issue. I told my friends who now use him exclusively. Good person honest mechanic. Philip S. Clayton, CA

They went out of their way to accommodate my needs. They explained every thing to me, and even took my motorhome to finish the smog testing.

Tim is the Most Amazing Mechanic I’ve seen in my 40 Years in the Car Business ! With 3 ways to fix the blend door ! He choose the one for the customer’s best pricing ! The dealer low balled Me & He took a 8 hour job to four hours . The factory set the HVAC actuators to the wrong pressure ! Tim re-set the actuators In The Body Control Module (BCM) after he was done . We now have heater & A/C back again .Tim is a Get Her Done kinda GREAT mechanic! Thank you so much ! After 40 years in the car/truck business He is the go to Guy of Auto Repair . ??????
