They strive to maintain the feeling of friendship and family that has always been a hallmark of our practice.
Dental Practice History
The practice was established by Dr. Marlin D. Walker in 1965. Dr. Marlin Walker graduated from Emory University College of Dentistry before serving in the Air Force for two years. When he began practicing dentistry, he was honored to become only the second full-time dentist in the entire Brandon area. Dr. Marlin Walker retired in 1998 after serving the community for 33 years.
When Dr. Marlin Walker retired, Dr. David Walker’s friend and dental school classmate, Dr. Eric Raynal, brought his skills and personal touch to our practice for 23 years before retiring in 2019.
Dr. Sarah Barr joined the practice upon Dr. Raynal’s retirement. She and Dr. David Walker intend to continue the practice’s traditions of quality dental care and feeling of family.
Our entire team looks forward to serving the Brandon community as your trusted dental provider for many years to come. We hope you enjoy learning a little more about us!
