It takes a synergy of qualified professionals to work on today's complicated vehicles.  A synergy cannot happen with ever changing employees. Denny has managed to keep his family and technicians around for a long time.

Denny Grinold, president and founder of Denny's Auto Diagnosis established in 1969!  He made famous his "Super Tune" back when engines could be modified.  He brought the business from a two bay gas station to a well equipped 7 bay service center!  Denny also established a fine reputation all of us at Denny's Auto follow and admire.  Is he wrenching still?  Occasionally, if not, he's still working hard somewhere in the shop -- Or, out on Lake Michigan fishing!  Denny operates the charter boat "Old Grin" out of Grand Haven in the Summer.

Denny's son Tim has several roles.  Foremost, he is the acting service manager, service writer, computer network operator, WEB Master, ASE certified technician.  Originally, Tim earned psychology degrees from LCC and MSU while working at Denny's Auto as a service writer and light auto repair guy.  Tim eventually decided that repairing automobiles would be more enjoyable than repairing people.  So, he earned his ASE certifications to work on autos!  Tim also enjoys Lake Michigan and fishing very much and even served in our Navy aboard the USS Wisconsin -- "Back in the days".

Now, I tried to get individual pictures of the "girls", but just couldn't break them away from each other!  So here they are: Jenny, Jeanne, and Jenna.  Three generations.  Three J's.  Jeanne is our matriarch and the one everyone listens to, Or else!  Actually, she is the sweetest lady you could meet and she will even get you a ride in the morning in Jeanne's Shuttle.  Jenny has helped her father since 1983.  As Secretary, Jenny has several responsibilities.  Most important is her relationship with our customers in which she takes appointments and writes up customers for service.  Jenna?  Well, we will just have to see.  She is only a teeny bopper!  Currently, she is more interested in horses and has won many awards. 

Ever notice how well maintained Denny's Auto is?  Well, Tyler gets it done as Facilities Engineer.  This guy is a very hard worker with a great attitude for working.  Tyler is a devout Detroit Lion's fan.  Want to know about any hot fishing or hunting spots?  Tyler is an outdoors fanatic and is in the "know".  If he was not hunting or fishing last weekend, something is wrong!

ASE and Michigan Master Technician Kim Eberhard has been with Denny's since August of 1975!  That's 32 years of getting people back on the road!  Kim has also been married since 1975 to his lovely wife Kimberly.  They have two daughters, Courtney and Hillary -- And two grand children Makaha and Aurora.  Obviously, this guy has many stories to tell and plays a major role at Denny's Auto.  Kim is known for his methodical approach in automotive diagnostics and communications with customers.

ASE Certified, Dan Jones has been with Denny's Auto since 1979!  Dan has an exceptional mix of "Old School" and "New School" technical abilities.  A.K.A.: IRON MAN.  Dan has missed very few days in his career here at Denny's!  Now TENACITY is an important trait every good must technician have.  Dan has been with his beautiful wife Barb since 1981! 

ASE Certified technician Joey Whitford has been with Denny's Auto Diagnosis since 1986.  Joey started out at Advanced Automotive Services in 1980 (age 12)!  Joey is a race enthusiast and used to compete at Spartan Speedway.  This soon took the back seat to raising three beautiful girls Summer, Lily, and Jessie with his lovely wife Bonnie.  Joey very much enjoys the challenge wrenching on high tech automobiles and has earned ASE's Advanced Level Specialist Certificate!
