Since graduating from Boston University, Dr. Nguyen has remained in private practice around the Boston area before finding her home at North Smithsfield Dental Associates. She greatly enjoys restoring patients' smiles with a focus on both esthetics as well as function. Many of her patients have complimented her on her gental hands and the comfortable experience she provides for them. When not practicing dentistry, Dr. Nguyen enjoys spending time with her family and friends. She also enjoys hiking, staying active, traveling and rewarding her tummy with delicious food!

Dr. Denise A. Sloane, D.M.D.

Dr. Sloane was born and raised in NYC. Upon graduating from Michigan State University, she spent a couple of years doing research at Cornell University Medical College. It was while volunteering in their dental clinic that she found her true vocation. While attending Harvard School of Dental Medicine, she fell in love with New England and decided to make it her new home. She completed a dental residency program at Rhode Island Hospital Providence VA Hospital and began practicing in North Smithfield upon its completion. She has been in our office for over 25 years and has been an active member of the Providence Chapter of the Seattle Dental Study Club for over 20 years. She enjoys knowing that some of her patients are the grandchildren and great-grandchildren of patients, she met when she first started practicing.

In her free time, Dr. Sloane enjoys biking, hiking, snow shoeing and cross country skiing. However, her absolute favorite pastime is going on long walks with her 3-year-old rescue dog Abbigail or "Abbigirl" as she likes to call her.
