The people who will actually treat you
Every specialty at Northridge Dental Group is covered by a dentist who trained in it. That is the practical reason patients are not sent across town for implants, gum surgery, or a root canal.
Who leads the practice
Both doctors own Northridge Dental Group and both still treat patients. Between them they cover the cosmetic and implant work on one side, and periodontics, jaw pain, and sleep medicine on the other.
