Dr Martinez is the best he is very meticulous. The staff here are so lovely, knowledgeable and make you feel so welcome. They have all up-to-date equipment. They even do retainers. I love it here, but I hate going to the dentist. The bonus is he looks like Jeremy Piven and sounds like him too:)

I couldn’t wait until y’all reopened after pandemic 😷 crisis . My heart was set on GREAT WHITE DENTAL to pre prep my wedding smile ! A young lady by the name Kaprice assisted me through my pre journey (not quite done yet ) and she has a lovely approach to customer education and reassuring process . She’s awesome !she works with the customer in mind and asks frequently “if I’m ok or feel ok while working on my teeth . That’s awesome , the after effect is not painful meaning she knows what she’s doing . THANK YOU GIRL ! this is your calling ! sorry for my horse teeth ! They’re

I always have a great experience when I visit Dr. Martinez. He and his entire staff are extremely hospitable and always keep me well informed. I don't believe I have ever had to wait more than a few minutes from my scheduled appointment time. I highly recommend Dr. Martinez and his practice.

I have been absolutely impressed with this dental office. Everyone here has been so genuinely nice in person and over the phone. The atmosphere is so relaxing and friendly and not once have they tried to up sell something. I see Dr. McMahan and she's an absolute delight.

I have always had an excellent experience with Dr. Martinez and his amazing staff. The office staff make everything so easy with your insurance and setting appointments. Dr. Martinez has great bedside manners and I have never felt more at ease with my treatments. I would RECOMMEND Great White Dental to all my family and friends.

I am so glad I came across the dental office!!! I have had some horrible experiences and was TERRIFED to go to a dentist but I couldn't put it off anymore. Had to have 3 extractions, 2 were a little complicated and they made me feel so comfortable and i didn't feel a thing!!! So glad I was able to take care of my teeth!

Everyone knows going to the dentist isn't typically the most exciting thing on your to do list. Great white dental makes the experience comfortable and as pleasant as possible. My favorite thing is definitely the people who work here. The dentists are informative and explain what they are doing, show you photos of your X-rays to help you understand and give you any options that you may have. No question is a stupid question here. They even have Carmel flavored flouride. There are tvs above your head that you can watch. The receptionists are always very welcoming and friendly and never run

Got all four of my wisdom teeth taken less than two months ago and let me tell you, AMAZING experience! I'm not very familiar with the San Antonio area just yet (I'm new here) so I came across dr. Alvarado on ZocDoc and he just happened to be the first doctor on the list.

The entire week before my appointment, i had anxiety and i was scared of the pain that was yet to come! Literally - every video i watched, made it seem as if it's gonna be one of the worst experiences ever.

A huge thank you to Dr. Alvarado & his assistant for taking care of me because they proved me wrong
