About Vital Auto Service

Greg Brennan
Gregory Brennan

Vital Auto Service, LLC was founded on the combination of two passions - working on cars and helping people.

Since he learned to drive, Gregory Brennan has always had a passion for vehicles and a profound fascination with the way they work. Greg has an Associates Degree in Automotive Technologies and has been professionally servicing vehicles since 2004. With a wide range of experience from maintenance to diesel engine diagnosis and repair, Greg has the information, and dedication to the field you want in your technician.

Within the time Geg has spent in the field, he has often heard horror stories from people who took their vehicle into the shop for seemingly small repairs only to be hit with a bank-breaking estimate.

Those estimates always included the services that were necessary to get the car back on the road, but then additional services that could easily wait for later when the customer could more easily afford it.

So Greg decided to start his own business where he could specialize in ensuring their customer's vehicles were safe to drive without the added expenses of unnecessary up-sells. Having a factory trained technician on your side, you can be assured the repairs you need will be performed in a timely manner, with a professional and personal touch, and without breaking the bank.

Satisfied Customers

I wanted to share the great experience I had with Gregory at Vital Auto Service today. He did everything he said he was going to do at a very reasonable price. He was prompt getting back to me and kept me updated throughout the project on my truck. He will now be getting all of my Auto Service business. I would highly recommend him to anyone.

Greg has done repairs for me several times, saved me significant $ and also was great about explaining exactly what needed to be repaired and the most economical way to do it. I appreciate that he takes the time to really talk to you and answer your questions. (I really hate it when mechanics blow me off because I'm an older woman! I'm not too stupid or old to understand. Really.) Thanks, Greg!!

I'm so thankful I found Greg - he's my new neighborhood mechanic. There was something not right about how my car handled but I had trouble explaining it. He was able to quickly diagnose the problem and give me a repair estimate for the parts and labor. It was the control arm - he showed me the broken part and explained what failed on it and his suspicions on why it failed. It turns out that the friend-of-a-friend who replaced it a couple of years ago hadn't installed it properly. I feel so much better knowing that it was done properly this time by an ASE certified mechanic! 5 out of 5 stars!

Christine C.

Had to have a water pump done on my car, instead of taking it to a dealership or any other private shops I went here because I was recommended by a friend. All the work was done very quickly with great communication, as well as getting a great price on getting the work done. Would definitely recommend to anyone that needs some work done on their car that is considering saving some money and looking at private mechanics!
