"Dr. Birnbach spent more time with me on this first visit than my last Dentist did in the previous 10 visits combined. Very thorough, explained everything, and everyone from front desk staff to the Hygienist were exceedingly cordial, gentle and gracious. Cost me a bit extra to make the move but so glad I did."

"Kim's care and attention to detail as a dental hygienist is exceptional. Also, I really appreciate the care and rigor in the office to maintain a safe setting during Covid.

Amenities like eye masks or dark glasses, headphones to listen to music, and even blankets if you feel cold ... so rare in any medical setting ... are standard fare with Boulder Smiles.

Dr. Birnbach is a master at his craft. HE REALLY CARES.

Boulder Smiles is top notch.

From the minute I walked in the door yesterday until the time I left, I was treated with the utmost warmth and caring. Thank you Bouldersmiles! I’m smiling in Nedeland!"

"I've gone to Dr. Birnback off and on for 35+ years. His work is excellent and I know that I can trust him. I strayed once and went to a different dentist in 2004 to remove my old mercury fillings and replace them with clean white porcelain ones. The difference was thousands of dollars and the dentist in Louisville also offered free nitrous. Then he poisoned me with mercury fillings and a very sloppy job & I have suffered for 17 years with mercury poisoning!! It ended up costing me another $10,000 to get rid of the mercury trash he put in my mouth. This was the BIGGEST mistake of my entire life!
ADVICE: Never cheap out when it comes to your health because 9 times out of 10 you will pay for it later.
