What Clients Say

Opening quotation marks.

Dr. Thomas saved my tooth after a second-opinion. Another specialist pushed an unnecessary implant and said it was fractured without proof. She took X-rays, examined it, and recommended minor surgery to redo a root canal. One year later, no issues.

⭐️⭐️⭐️⭐️⭐️

Opening quotation marks.

Dr. Thomas is the best periodontist I have had by far. She is friendly, caring and intelligent, takes the time to explain, and loves what she does. She took care of 2 implants with minimum pain and I had no issue afterwards. I very highly recommend her.

⭐️⭐️⭐️⭐️⭐️

Opening quotation marks.

I just went to Dr. Thomas for a bone graft for an upcoming implant. I can honestly say she has got to be one of the top periodontists there are. She and her staff are very warm and welcoming and make you feel totally comfortable.
