Airway Friendly Orthodontics in Frisco


Dr. Greenberg treats children, teens and adults for all their orthodontic and sleep disorder needs. Because of his extensive airway training and growth and development knowledge of the face and airway of patients, he is uniquely qualified to recognize and address obstructive sleep apnea issues. At RxSmile, we strive to educate and assist our patients in making informed decisions about all their oral health needs, while creating a warm, friendly and fun atmosphere.

I was referred to Dr. Greenberg’s office while at a consultation with Invisalign. The woman helping said “his office is a favorite for our clients. They are so kind and patients have nothing but great things to say about their team. I highly recommend his office!” So naturally I chose Dr. Greenberg’s office to start my treatment. I was greeted by the most friendly and professional staff. Gayla took the time to thoroughly explain treatment options and answered every silly question I had. Gayla and Dr. Greenberg were very conscientious and conservative with treatment suggestions, and are extremely knowledgeable. Everything is state of the art and they don’t pressure or upsell you. It’s evident that patient satisfaction is their first priority and are experts at putting together a treatment plan tailored to you. I highly recommend this office and am very excited to start my treatment with them!

Exceptional service with highly professional, personable, experienced and talented staff. Dr. Greenberg and Gayla made my first orthodontic visit very comfortable and am confident in the treatment plan they recommended. Highly recommend RxSmile!

Nicole F.

Leuran, Lisa and Holly were all awesome at our visit today!! All 3 of my boys have seen Dr. Greenberg and have beautiful teeth now!! Love his office and his staff!!

Heather S.

From the minute I stepped in Gayla greeted me with a smile. Wonderful, professional, super fast, beautiful location, and Dr. Greenberg was spot on. I am so excited to see the end result.

Sandra P.

Our first encounter was Lisa at the front desk, who was courteous and calm, welcoming us with a smile, then Gayla took us in for a photo session and she was very pleasant and sweet, answering my questions and explaining the events of the consultation. Then we met Dr. Greenberg, who was genuinely brief but pleasant. He asked the patient what bothered her the most to initiate an objective focusing on patient needs, which I believe is very important and unique. Isha, Dr. Greenberg’s assistant, was very knowledgeable, professional, and thorough with the initiation of the braces and patient education. The office seems very clean, and I actually saw personnel cleaning the seats thoroughly as I was waiting, which is very reassuring. In all, everyone was helpful and made our visits comfortable. Also, they have a super cool selection of music playing in the office! I can’t wait to see the transformation using the Damon brace system.

Moo M.

Wonderful from start to finish! The entire staff treats you like family. Lisa, Gayla and Dr. G are just the best and keep us all laughing. If you haven’t been in to see all of the really great things they are doing to make your orthodontics experience easy and fun, especially for the teens, then run, don’t walk over there today.

Carey F.

The absolute best experience. Dr. Greenberg made my sisters teeth perfect decades ago so I brought my daughter to him for braces. Another perfect smile. The staff is awesome as well. Thank you Dr. Greenberg!

Nicki L.

Best orthodontist. Best Staff. Dr. Greenberg is everything you would want and expect in an awesome orthodontist. Leuran always welcomes you with a smile and not sure how she remembers everyone’s name. Joei is friendly and pays attention to detail. Highly recommend this team.

Hailee M.

5 Stars! We highly recommend RxSmile! My kiddo loved it and they made her feel very comfortable. Our daughter said she would give the visit 5 stars! The technology is awesome, the staff is professional, and the office is cleanly and tidy. Dr. Greenberg took his time with us and we left feeling very informed.

Nancy L.

My son needed a new retainer – I brought the mold by and thought it would be days before getting a new retainer and thanks to Tiffany and Kusandra, I was able to have a new retainer in under 15 minutes! Thank you to the entire team!
