Nickole Scolastico

Dental Assistant

After graduating from the Lincoln Technical Allied Health Institute, Nickole began working in a large multi-specialty practice, where she quickly rose up the ranks to being the head assistant.  The corporate style of dental practice left something to be desired for her, and, in subsequently joining our team, Nickole's clinical excellence, focus on quality, and down to earth warmth found a perfect home.  Her background as a cheerleader continues to manifest in the smiles she puts on the faces of our patients and in the half-marathons she loves to run for charity.
