Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Wonderful
Went in for wisdom teeth removal. All of my teeth were impacted and Dr. Thomas was very accommodating. I called him and explained that I was home from college only for a few days and he managed to fit me with only a weeks notice. He took care of me and I didn’t have to miss any class.

Excellent Work
Dr. Thomas removed my wisdom teeth and was an absolute savior! Surgery was quick and efficient, and he was very accommodating to my concerns over his recommended pain killers post-surgery. When I experienced discomfort two weeks post-op, he came in to see me when the office would normally have been closed and resolved the issue for me free of charge- and within minutes.

Professional ability
As a laboratory who often works directly with surgeons in prosthetic implants and parts used in maxio facial reconstruction and oral reconstruction I have worked with Dr Gred Thomas closely for over a decade and have found him to be one of the most competent surgeons I have had the pleasure of working with. His skill level and attention to detail and the easiest and most difficult cases is always part of the treatment and the results consistently superior to other surgeons I work with. For maxio facial and oral surgery I would recommend his practice as a first choice decision.

Cosmetic procedures
I came to see Dr. Greg on a recommendation of some of my girlfriends on some cosmetic procedures to remove some lines and wrinkles. He was very easy to speak with and accommodated all of my questions and desires. The procedures were done quickly with minimal pain ( some numbing shots) and turned out beautifully. The lines and wrinkles vanished and my appearance was much more youthful. I definetly will return for any follow up and very much recommend his practice and himself for anyone looking for a younger look.

Awesome
I was scared of the visit and he totally changed my mind. I have seen quite a few surgeons and none compare to him. He listens and is kind. Every question was answered .I felt like I was talking to a family member. The surgery went great and I never needed any pain medication . He didn’t even charge me for an X-ray I forgot at home and it needed to be repeated.

Dr. Thomas as a surgeon is awesome. But I am going to warn you DO NOT under any circumstances ever use the lab they suggest especially if it is the brother of Dr. Thomas. They are the worst lab ever!!!! The denture they made to be attached to my implants started to fall apart after 3 months of being placed in my mouth. Teeth fall out of acrylic, pieces break off, the bottom line is very simple their work is horrendous!!! can't even bite into a piece of toast without teeth breaking off from the denture. DO NOT let them talk you into using them no matter what. This surgery was extremely expensive and in this day and age an excuse of the denture was not made to last is a crock. The work of Dr. Thomas's brother is the problem. Run far, run fast from this lab they are the worst. Things should not start to fall apart piece by piece in three months after being place. RUN, RUN, RUN, AS FAR AND AS FAST AS YOU CAN!!!!!

It has been years -but the hell I went through years ago is like yesterday. This dr put defective 3i implants in my upper gums -where a few months they failed and one got so infected it went thru the Sinus and almost to brain. The process left my face shallow and asymmetrical-uneven, He recharged me for new implants. He gave the ok to have a dentist fit me with a permanent fixed upper denture-in days my face and gums blew up as the implants was defective. He also did a face and brow lift at the same time -I trusted him as he had many before and after photos of facelifts and etc in his lobby. It was done at the same time as defective implants being installed. It was botched as well as the implants. No apology-just arrogant and unaccountable. Do not go here. The reason I’m bring up now is because I just came accross this site and al having problem with implant. He destroyed my face and my upper lip sags after his surgery . Another patient went thru the same implants failure at the same t

He’s arrogant, apathetic, and completely lacks communication skills. Had an issue and he spent probably 10 seconds with me. The rest of the staff is great. Thankfully they are there or I would’ve been 100% on my own. Go to literally anybody else.

Dr. Thomas has removed teeth and put in a couple of my implants. He was always caring, gentle and thorough. I've had these implants for years and feel it's the best thing I've ever done! I highly recommend him, any of the doctors as Summit and the staff!

Pompous is the best word to describe Spent little time actually caring for me post surgery. His focus was solely on HIPAA. The staff and other docs at Summitt are excellent!

If you value your life, do not go to this doctor. He did not do biopsy twice when I complained of painful black spot. Had to get a different doctor do biopsy. His misdiagnose almost cost my life.

Everything from scheduling , to procedures to after care was top of the line . Dr. Thomas and his staff go over and beyond to make sure patient comfort and care are well taken care of . I had two major surgeries , and I couldn't have asked for better care . I'm a very anxious patient when it comes to dental care, but I felt very at ease and safe at Dr. Thomas's office , and I am always highly recommending him and his office to whomever is looking for an oral surgeon.
