Our Team

Dr. Tom Nussear

IMG_2765Dr. Tom Nussear was born and raised in Hagerstown, Maryland. He graduated from Smithsburg High School where he excelled on the football field and helped his team bring home the 1989 State Championship Title. After high school he moved onto University of Maryland, College Park where he obtained a bachelor’s degree in chemistry. In addition to his studies, he devoted an abundance of time cheering on the Terps. After his time in College Park he moved to downtown Baltimore to pursue a degree in dentistry from University of Maryland Dental School. During his time there he married his high school sweetheart, Mary Ann. Baltimore provided the perfect backdrop for Dr. Nussear’s love of sports. Viewing both stadiums from his apartment was just one of the perks of living in Baltimore. After graduating from dental school in 1999, Tom and Mary Ann moved back to their hometown. After a few years of practicing as an associate in the Hagerstown and Waynesboro areas Dr. Nussear took a leap of faith and returned to his roots to open his own practice in downtown Smithsburg, Maryland. The hometown feel that Dr. Nussear’s office provides to patients is unsurpassed. In addition to his private practice, Dr. Nussear also works part time at Walnut Street Clinic so that he can maintain an active role in Community Health. While not at the office, Dr. Nussear enjoys golfing, doing yard work, being a sports fan, and spending time with his wife and three boys Cole, Will, and Jake.
