William M. Callahan DDS

We’re excited to have Dr. Bill Callahan D.D.S. join our dental team at Family Dentistry of Seneca. He brings an extensive resume of clinical experience and shares a love for organized dentistry. We’re excited to have him on our team because he is a dentist who cares deeply about the quality dentistry he performs for his patients.

We are thankful for Dr. Callahan’s skilled hands as a gentle dentist in Seneca, South Carolina.

William M. Callahan began his practice in Atlanta in 1980 after receiving his dental degree from the Emory University School of Dentistry. He began working in Atlanta and moved to South Carolina following 27 years of private practice. He practiced dentistry for 7 years in Westminster following Dr. Johnson’s retirement.

“I love to pay attention to the very small details that make a dental crown that lasts for many years.” Dr. Callahan should–he won awards at Emory University to his attention to detail while making dental crowns and bridges that look like natural teeth. Dr. Callahan began placing realistic teeth on dental implants over 20 years ago. Dental implants let us make a tooth that fills a hole or space without having to reshape the adjacent teeth.

His list of accomplishments, recognitions, and achievements is long, but he would tell you that he is most proud of his family–Lynn, his bride since 1978 and their three children B.J., Joey, and Kathleen.

Got me in the same day!! I had a problem. Never have I been able to get in to a dentist on the same day, let alone have all my needs provided that day! Highly recommend!

Dr. Josh Murphy is one of the best dentists I have ever been to. I don't generally like to go to the dentist but he has made my last two visits less stressful. He explains everything and is very attentive to his patients. I would definitely recommend him to anyone!

It was the most friendly and prompt service that I have ever received at any medical facility in my life. It is a true pleasure to go there.
