Matt is awesome. He was left alone in the store near closing and realized that my car needed extra parts. He took care of it and completed the job that night as promised. He and his crew even stayed late to help others get their cars instead of closing and keeping the cars over night. No way he is getting paid enough for how well he treated the customers both in the store and on the phone.

When I first met Matt McGarth he was working at the San Tan Valley location at Gantzel and Ocotillo. I went in for an oil change and subsequently found out my water pump was bad ..... and my serpentine belt was needing replaced. At the time I was unemployed and going through a divorce and didn't really have the money to do all the work. Matt helped me decide which repair to do first but in the end all the repairs were completed that day. When Matt was totaling up the charges he kept part of the bill separate. I told him what I had to work with so the remaining balance he stepped around the counter and paid for himself. I've NEVER experienced the service that I had that day. I decided that day to go to whatever location Matt is working at because of his sincere desire to help people. I live in SAN TAN VALLEY with a Big O store five minutes from my house but I will drive 35 minutes to receive the service I get when dealing with Matt.....awesome person awesome customer service!!!!

I needed tires and went into the store. Matt greeted me and helped me with my tires. I didn't have the money and Matt helped me get approved for financing. He was very helpful and made me feel at ease. I would need is $40 and he would put my tires on. Then the most amazing thing happened. I told him I didn't have enough for the fee and didn't get paid for two weeks. He took out his debit card and paid the fee for me. When I asked him why he did such a thing? He said it was because he knew I had children and it was unsafe to drive my van with the tires I had on it. Thank you Matt and thank you Big O Tires.

I came in for an oil change last Thursday, I have used this location for years and I have always had good service,My only complaint was the length of time for my oil change.I had a 9am appointment and didn't leave until 11:20am.I wasn't expecting such a long delay.Thankfully I had an hour long conference call to take up some of the time.The service person did apologize and give mea free oil change for next time.I will continue to use this location, but I hope next time they are realistic with how long I will take.

They did a great job and service was awesome they did it on time

They do a great job with our oil changes on two different vehicles.

On this occasion the service was good.I had steering /bad tire issues.The service mgr that helped me was very articulate in explaining what was going on and covered all the bases to check out my situation. This was my first experience with this particular mgr.He has been with your company for 6 years.Sorry cant remember his name.If I knew he was going to remain at this store I would make an effort to come to this location exclusively.I have had multiple disappointments in the past with repairs at this store.I tend to not seek you out for anything other than tires.FYI.My biggest aggravation with Big O is the continual turn over of Mgrs.I cant build a relationship with anyone.

I was very satisfied with my service. I just got an oil change, but what made it very nice was I felt the gentleman who helped me that day was very honest with me. I am sure he was still trying to up-sale me but he was very kind, explained everything thoroughly, and I just basically felt he was truthful.The only thing I wish auto stores in general could figure out is a timing system. I know I put off going in far longer than I should or do not get additional services because I can never plan around the very loose time estimates. Overall, I've been there a few times and there is a great staff and good store.

Great employee. Used several times to have tires installed

I was shopping to replace some worn low-profile tires on one of the family vehicles. George made it clear that he "would meet or beat the competitor's price". The competitor did not make the same offer.When the competitor (Discount Tire) did provide a better price, I felt like I should at least give George a chance to make good on his offer.He did, and he was able to get the tires from the warehouse on the same day for installation. Pretty impressive!
My only recommendation is that they have the service techs CLEAN OFF the hand-print filth from the rims once completed. When a customer spends hundreds of dollars, it's the difference between GOOD and EXCELLENT.

Always friendly. Neighbor friendly not, superficial. Bad day and made it better.
Shout out to George. Business's just don't treat you like this anymore.

I spoke to Mike and informed him that I felt I needed a wheel alignment I had just been there for tire rotation six months earlier. He was very very thorough put it on the rack and check everything. Very attentive called me within an hour and a half with a solution to the problem great customer service very satisfied customer .

Big O Tires was there when my transmission went out. It went out at 202,000 plus miles on a 13 year old Chevy Avalanche. Why didn't I lose the original transmission sooner? I believe that it didn't fail any earlier on my truck because I had regular maintenance checks at Big O. I've come to trust them. They offered me multiple alternatives to the issue. I picked the one that made the best sense to me (a rebuilt transmission with a three year guarantee). I have children's college expenses to pay, so even with how old it is, I need this truck to carry-on. Buying a new or used car is not an option. Big-O understood that and worked with me. Thanks! I am "back in the saddle/seat once again."
