Nicole

Front Desk/Management

Hi, I'm Nicole. I graduated from Sawyer School of Business in 1992. I have 30 years experience in general dentistry, having worked in four offices. I have clinical and administrative background, which I feel helps me with an overall understanding of your treatment. I am originally from Beaver County and currently reside in North Strabane with my fiance' Patrick and our dog Bella. I am an active Ladies Auxiliary member of the American Legion. My time away from the office is spent with family and friends. We enjoy traveling, visiting wineries/breweries and riding bicycles.

Allison

Front Desk/Management

Born and raised, and still reside in the South Hills of Pittsburgh. I am a graduate of the University of Pittsburgh BSN program. I have been in the dental field for 21 years. I started out working as an assistant for an endodontic group, then moved to the front desk - I loved to see the patients that came in so nervous and worried leave so happy and surprised at how root canals were not awful like people had told them! After 10 years in endodontics I moved into general dentistry and have been here ever since. I still love to see patients that believe having dental treatment is awful saying how enjoyable their experience with our staff and doctors was! This is only the 3rd dental practice I have worked in. I live in Bethel Park with my husband and 2 children, as well as a dog, cat and guinea pig.
