Dr. Tom Gallaher
Dr. Gallaher graduated from West Virginia University with a Doctor of Dental surgery degree, in the same hospital he was born 24 years prior. Growing up in a small town, he realized that he wanted to make a difference in the health/livelihood of people on a day-to-day basis by getting to know each patient and changing their perspective on dental care. While living in Hawaii he discovered that all patients want basically the same thing: a doctor/dentist that takes the time to listen and provide individualized attention/treatment while ensuring top-notch care in a timely and comfortable manner. In his spare time, Tom enjoys most sports, traveling, playing with his Papillon, spending time with family, and reading. Dr. Gallaher lives by the golden rule, and believes that with advancements in technology in healthcare, patient comfort and satisfaction will continue to improve. He is very excited to join Henritze Dental Group and continue ensuring comprehensive, comfortable, and quality dentistry for each patient.
