Our Proud Tradition

Dr. Keller had the privilege and honor of assuming responsibility for the practice; formerly held by Dr. Robert Hortin.

Dr. Hortin practiced dentistry and orthodontics for nearly 48 years, 44 of which were right here in Sunnyvale. He has maintained an exemplary reputation as a moral, ethical, talented, and dedicated member of the orthodontic profession. He is a member of the Angle Society of Orthodontists, the most exclusive international organization in the orthodontic profession. Dr. Hortin searched for many years to find the right person to join his practice and was extremely pleased to find in Dr. Keller someone who could carry on his proud tradition of excellence in clinical practice and service to patients and the community.

Dr. Hortin and Dr. Keller practiced side by side for several years in an apprentice relationship. After his retirement in 2006, he has continued to consult with Dr. Keller and is serving as her mentor in her process of joining the Angle Society.

Previous patients of Dr. Hortin are always welcome in the office. We have many families who are third generation patients. Dr. Keller is proud to have joined such an illustrious practice and is committed to a long tenure in service to the patients in our community.
