Gary joined the practice in 1991 and took over as principal/owner of the practice in 1998. He enjoys providing general dentistry for the community and has also been successful providing the In-Line Clear Removable Brace System to treat crowded and misaligned teeth in adults for several years, having been so impressed after he treated himself with the system.
