Dentist Where Experience Counts





Our Dental Office

Welcome to the General Dental practice of William M. Callahan, DDS the dentist where experience counts! We are proudly located in Westminster, South Carolina, at 104 West Oak Highway at the corner of SC Highway 24 and US 123/76. We have been serving patients here since January 2007. Previously, Dr. Callahan practiced in Atlanta, GA., having graduated from Emory University School of Dentistry in 1980 and where he served on the school's faculty until the school's closure in 1988. He continued to practice General Dentistry in his private practice in Atlanta. Dr. Callahan joined Dr. Garland Johnson of Westminster in January 2007 in their new dental office. Upon Dr. Johnson's retirement, Dr. Callahan became the owner and, along with the staff, the sole provider of dental care at the office.

Having practiced for over 31 years, Dr. Callahan continues to broaden his education and services by pursuing additional dental education every year. The dental office was designed, built and furnished with the most current and state of the art equipment. We offer total digital radiography (x-rays) and the latest in infection control procedures to provide the most protection for our patients and staff. We always provide the latest technology in anesthesia and pain control, in our ongoing effort to provide the best dental procedures in the most comfortable environment possible.

We also have an experienced staff, with Debbie Smith, Peggy Carson, Dionne Burrell and Paula Gray, all local residents of the area, providing knowledgeable dental support for our patients. They each provide their own valuable care and skill, having been in dentistry for many years!

Our entire staff welcomes new patients and enjoys taking care of our existing patient family in a caring environment, where experience counts!
