So professional. I got an 8 page summary of all tests performed and pictures of those things that needed repair. I was treated well and left with a smile!

by - Verified Customer December 20, 2017

Waited a long time for the shuttle.

by - Verified Customer December 20, 2017

D&H always keeps me informed about work needed.

by - Verified Customer December 12, 2017

I am quite pleased on all the work that was completed.

by - Verified Customer December 10, 2017


by - Verified Customer December 10, 2017

The basic work was done to my satisfaction. A couple of mino issues I asked about were not looked at.

by - Verified Customer December 08, 2017

Pricing is higher than competition except dealership. Shop is friendly.

by - Verified Customer December 07, 2017

They seemed friendly and efficient.

by - Verified Customer November 16, 2017

They were professionally done.

by - Verified Customer November 13, 2017

I am still waiting for the final repair to be done.

by - Verified Customer November 08, 2017

I have been using D&H expertise and have always been completely satisfied. They actually fixed something that had been going on a long time and the Toyota shop never did.

by - Verified Customer November 07, 2017

Even the dealer said they wouldn't charge
$1000 for a 75000 mile maintenance job
I feel I've been had

by - Verified Customer November 06, 2017

The entire team is super!

by - Verified Customer November 06, 2017

Very disappointed

by - Verified Customer November 03, 2017

Service was great, very honest. will come back. D & H will be taking care of all our cars now.

by - Verified Customer November 02, 2017

Have always had a good positive experience. It is my repair shop of choice.

by - Verified Customer November 02, 2017

Prompt and courteous service.

by - Verified Customer October 31, 2017

Very satisfied.

by - Verified Customer October 30, 2017

Charlie and Nicole were amazing! Everything was explained to me beautifully and my car was ready so fast! I won't bring my car anywhere else for any maintenance or repairs! Thanks!

by - Verified Customer October 29, 2017

The employees were very courteous and listened to my comments and suggestions for the work to be performed on the car.

by - Verified Customer October 22, 2017

Very professional.

by - Verified Customer October 19, 2017

Great Front Office Staff... they explained everything that was recommended and allowed me to make the final decision.

by - Verified Customer October 18, 2017

My car had a alignment the other shops were unable to correct.
D & H was after several attempts able to remedy the problem. Thanks Dave for hanging in there to the end.

by - Verified Customer October 18, 2017

Everyone was extremely nice and very helpful. I will now be a permanent customer.

by - Verified Customer October 18, 2017

I went to this shop because it had giod ratings. The staff was very nice!
BUT I was overcharged for a cooling system diagnostic. My radiator was obviously leaking and i was told it was not put on the pressure machine because the leak was so obvious. So why charge $159 to look at an obvious leak. Also the qoute of the repair was almost $1200 for a new radiator. Price grossly inflated went down the street and paid $500. Yes D&H was cleaner and had a shuttle...

by - Verified Customer October 16, 2017

Excellent....Nicole,and everyone else were very helpful.

by - Verified Customer October 13, 2017

Dave and company always deliver quality work, with a smile. They are the only shop I take my vehicles to.

by - Verified Customer October 08, 2017

Great customer service - I loved that they sent me photos from the inspection. Will definitely recommend.

by - Verified Customer October 06, 2017

It would have been nice to have them check the lights on my dashboard when driving the car. Still have light out somewhere.

by - Verified Customer October 06, 2017

Very expensive. $2000 over another quote we received. We did not Move Forward with this company.

by - Verified Customer October 05, 2017

everything was great except that the car was ready 3 day later than the promise day.
thank you for your services

by - Verified Customer October 05, 2017

D&H is an excellent repair shop

by - Verified Customer September 22, 2017

I felt it was recommended that I have repairs that are not necessary. Another shop has looked at my car and did not agree with the recommendation.

by - Verified Customer September 20, 2017

Dave Kemnitz was able to squeeze us in to look at the vehicle. He and an employee were able to accurately diagnose the problem and took care of it. He also recommended a tire store for replacement of the four tires.

by - Verified Customer September 15, 2017

Good work and friendly service. But I think the cost is high for brakes, oil change etc.

by - Verified Customer September 12, 2017

Excellent service.

by - Verified Customer September 11, 2017


by - Verified Customer September 06, 2017

It was great. Very friendly and explained everything that was okay and what needed to be addressed.

by - Verified Customer September 05, 2017

I was impressed with the approachability and kindness of the people that I worked with at D&H, but I had a very difficult experience with my repair. The initial work seemed to address the problem, but one week later, a similar issue took place. When I towed the car back to D&H, they investigated, and told me that there had been a problem with the way the computer had been reset after the initial repair. They apologized, and assured me that they had now resolved it. Unfortunately, one week later, the exact same sequence took place, again resulting in a tow back to D&H. At this point, they referred me to another shop. It's possible that they are much more adept with certain makes/models, but for my 2011 Volvo, they were unfortunately not the right choice.

by - Verified Customer September 01, 2017

Although not cheap, there is a sense of professional treatment.

by - Verified Customer August 27, 2017

Sub-par pre-purchase inspection and really not worth $150. It's a shame. I think AAA should remove their approval of this shop.

by - Verified Customer August 23, 2017

A thorough analysis of trouble.

by - Verified Customer August 17, 2017

Always receive top-notch service.

by - Verified Customer August 16, 2017

The service given is always friendly and professional.

by - Verified Customer August 16, 2017

Questionable technical knowledge, poor follow through on their comments and extremely overpriced for the services.

by - Verified Customer August 06, 2017

Knowledgeable technicians, quality work.

by - Verified Customer July 25, 2017

Efficient, friendly staff.

by - Verified Customer July 20, 2017

I will be recommending the shop as they did a much better job on my Subaru than Subaru of Walnut Creek did.

by - Verified Customer July 18, 2017

Amazing people and service.

by - Verified Customer July 14, 2017

Our 1992 Yukon had failed its smog test and D&H was recommended by our local GMC dealer as the dealer didn't have the equipment to perform smog analysis for our vehicle. D&H has new green technology to remove carbon buildup in the engine. They also performed other related services. Vehicle passed with flying colors.

by - Verified Customer July 13, 2017

Terrible experience. I think I was given an extremely high quote.

by - Verified Customer July 10, 2017

I always go to D&H. Other places have 3-5 day wait just to pop the hood. Not at D&H.

by - Verified Customer June 29, 2017

Excellent service, quality repairs.

by - Verified Customer June 28, 2017

Had to go pick up my vehicle because they were too busy.

by - Verified Customer June 27, 2017

Very good experience.

by - Verified Customer June 23, 2017

Every experience, including the last one, has been has been absolutely satisfactory.

by - Verified Customer June 21, 2017

They are experts in their field. I completely trust them. Also, great value for the work done. I won't go anywhere else.

by - Verified Customer June 14, 2017

Quick, competent, reasonable price.

by - Verified Customer June 09, 2017

Great customer service!

by - Verified Customer June 09, 2017

I can't believe what a good experience I had here. While it was a little more expensive than the last place I went to, the reliable and up to date updates I got both by email and by voicemail were pleasant, and sometimes after their hours. When I had gotten the same repair done at another office, my car was back to breaking down weeks later. I am into three months, and the car is still running wonderfully and my gas mileage is increased. Thank you so much!

by - Verified Customer June 06, 2017

I had my first service with this company recently and they were friendly, knowledgeable, and competent.
