Viviana Avila-Gnau, DDS

Dr. Viviana Avila-Gnau obtained her D.D.S. degree from Loma Linda University School of Dentistry in Loma Linda, California, after receiving a previous D.D.S. from Pontificia Universidad Javeriana in Bogotá, Colombia. Her private practice experience includes managing her own practice in Bogotá and serving as an associate at practices in Maryland as well as in the Boston area and in Manhattan. She also has significant teaching experience, including faculty positions at Loma Linda University School of Dentistry, Tufts University School of Dental Medicine, and New York University College of Dentistry. She was selected for training in leadership and evidence-based dentistry programs with the American Dental Association, achieved fellowship status in the Academy of General Dentistry, and is a member of the American Academy of Cosmetic Dentistry and the American Academy of Dental Sleep Medicine.
Dr. Avila-Gnau has a genuinely caring chairside manner. She is able to make even the most anxious patient feel relaxed; her greatest satisfaction comes from the happiness expressed by her patients as their anxiety subsides, their dental health improves, and their smile brightens. The smiles she brings to their faces bring a smile to hers!
She gives each of her patients the individualized care and attention they deserve, building strong rapport and deep loyalty. One of her patients even returned to Boston for appointments – along with her mother – after they moved from Boston to Seattle!
In her spare time, Dr. Avila-Gnau enjoys spending time with her husband and two young children, and sharing her love of dancing and Latin music with the students in her Zumba classes.
