About Us



“I have been a patient of Dr. Frank's for over 15 years, and during that time I have received exceptional care. Dr. Frank is competent, compassionate and professional. Because she is dedicated to providing the best service possible, she attends ongoing training to upgrade her skills. As a result, she is very knowledgeable, and with each visit she offers helpful advice to ensure that I achieve the best possible outcome. She provides a wide range of services. In addition to dental treatments such as fillings, crowns and minor cosmetic treatments, she has prescribed custom night guards to prevent us from grinding our teeth during sleep, diagnosis and a device to address sleep apnea, and Invisalign for my daughter and me.

Dr. Frank is fortunate to have very capable and caring staff. Julie is a hygienist and Claudia serves dual roles as both hygienist and office manager. Together with Dr. Frank, they help to make what might otherwise be a dreaded ordeal something I have come to look forward to! I have visited many dentists, but the service at Dr. Frank's office is superior to any I have received in the past.”
