We are a one doctor office, so you will always see the same provider and receive personal attention as we see one patient at a time. Dr. Grenzer is a Portland native and attended the OHSU School of Dentistry. He has been serving patients at this location for over 24 years. He is a member of the American and Oregon Dental Associations and stays current with the latest techniques, attending several continuing education courses each year. Our goal is to listen to your desires and provide the best treatment in a relaxed, caring environment.
