Dr. Jeffrey Head

Dr. Jeffrey Head


Dr. Head began his work at Glade Valley in 1983 and became a co-owner in 1986. He did his undergraduate work at the University of Maryland and graduated from the University of Georgia College of Veterinary Medicine in 1980. He and his wife Kim have raised six children – two boys and four girls along with a Noah’s Ark menagerie which has included numerous litters of Golden Retrievers and Shelties. Dr. Head’s Christian faith was instrumental in his choice of Veterinary Medicine as a profession, and he feels blessed to serve God in his career. He and his family are active members of Thurmont United Methodist Church where they help lead worship and sing as he plays his guitar. Kim can be seen helping out as a part time technician around the hospital.
