For decades, this practice has stood as a trusted health cornerstone in the Williamsville community, building its reputation not on corporate expansion, but on deep, lasting relationships with patients and families.

The practice's expertise is particularly evident in its commitment to integrating advanced technology with traditional clinical excellence.

Dr Glennon is awesome. Every time I think of him, I think he is the best dentist I've ever had. Very kind and Very Professional. His assistant on the other hand, needs someone else. The first time I went there to get my teeth cleaned she dropped the tip of the brush down my throat. Thankfully, my tongue was covering the back of my throat. He needs a new assistant.

He's the best dentist I've ever had out of the 3 I've gone too! My last dentist let small issues get worse by making me wait 6 months in between appointments ! He gets things taken care of in a timely manner, he's kind, makes me comfortable. I drive a hour just to see him and will continue! I like the small "hometown" feel of the office as well. 10/10 best dentist ever ! I'm grateful I found him. Perfect amazing dentist. Any other work I can totally trust him with. And I don't get sent to other dentist like the last dentist I had did to me. I like going to one dentist for everything I need done.

AVOID! AVOID! AVOID! I waited some time to post this review. Wish I could rate 0 stars. When I was 18 this dentist severely ruined my smile. Severely. The hygienist was very rude and the fillings I had done are absolutely terrible. This dentist destroyed my beautifuI smile not to mention I was in so much pain afterwords and he practically took away few of half of the teeth. Avoid like the plague for real !!! AVOID AVOID AVOID! YOU'LL BE THANKFUL YOU DID I PROMISE
