Mark Berkheimer, a Customer Service Adviser a Earnhardt Toyota, 6136 E. Auto Loop, Mesa, AZ, is the consummate Service Adviser. I have had Mark as a Service Adviser, as have my daughters, for years. He is always professional, very personable, genuinely concerned about his customers, and goes above and beyond the call of duty to ensure customer satisfaction. Earnhardt Toyota is very fortunately to have Mark and should recognize Mark for his abilities at every opportunity.
