Our Team

The Allegheny Smiles Team

Our Practice philosophy is to educate our patients about their dental health status and make them aware of the different treatment options available to them, so they can make informed decisions based on their individual needs.

Together we are dedicated to delivering customized dental care in a relaxed comfortable setting.
