Dr. Sarah Barr

We are pleased to welcome Dr. Sarah Barr to our dental team!

In keeping with the tradition of our practice, Dr. Sarah Barr has deep local roots—she is a Tampa native who grew up in the Apollo Beach and Brandon area. She grew up as a third-generation patient of our practice and worked for us as a dental assistant before she attended graduate school. Dr. Sarah is delighted to join our practice and see new and familiar faces as she continues to care for our patients.

Dr. Barr achieved her Doctorate in Dental Medicine from Tufts University in Boston, MA after earning a Master’s degree in Medical Science from the University of South Florida and an undergraduate degree in Exercise Science from Florida State University. She is also an active member of the Florida Dental Association.

In her free time, Dr. Barr enjoys all Tampa area sports teams and loves spending time on the water with family and friends. She is also a member of the Junior League of Tampa and finds joy in giving back to her community.


We are proud of our dedicated and caring dental team, each of whom was carefully selected to provide exceptional care for our patients at every stage of treatment–from routine hygiene visits to the most complex procedures. Our team shares the same values of continued educational development and dental industry advancements to provide the best dental care possible and strives 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 was a graduate of 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 enjoyed learning a little more about us!
