Solo general dentist operating from Suite 34 of the 306 Walnut Avenue dental building in the heart of Hillcrest's specialty corridor, Gregg K Johnson, DDS runs a four-day clinical schedule centered on routine restorative care, hygiene, and crown work. Endodontic referrals for molar root canals and retreatments travel one floor over to C&P Endodontics within the same building rather than across town, keeping continuity of care tight for patients mid-treatment. The single-operator format keeps appointment slots paired consistently with the same hygienist and front desk team, a model that contrasts with the high-volume corporate offices elsewhere in the neighborhood. Periodontal cases involving advanced bone loss or pre-implant site planning are sent to Mission Hills Periodontics - Dr. Stephen Munroe for surgical phase management. The most complex treatment regularly handled in-house is multi-unit fixed-bridge fabrication for posterior tooth replacement when patients prefer not to commit to an implant timeline.
