Purity is our chief dental assistant, helping in all sorts of procedures and providing the "extra" hands that directly assist the dentists. Purity has a degree in business management. However, after working in the business field for several years, she decided she really enjoyed helping others, and so turned to a career in health care. After returning to school to complete a program in dental assisting in 2007, Purity joined the Princeton Dental Associates. She enjoys working closely with the patients, and focuses on maintaining a calm and relaxed atmosphere in the office. Purity's greatest satisfaction is to see patients leave the office with happy smiles after their dental visit.
