Hidden market #1
Military & TRICARE families
San Diego holds one of the largest military concentrations in the country: major Navy and Marine installations, plus a large base of active-duty families (dependents can enrol in the TRICARE Dental Program), military retirees, and veterans. A practice that clearly states which military-related coverage it accepts, understands PCS-move turnover, and leads with family-friendly, fast-access messaging can reach a large, recurring base.
Hidden market #2
The cross-border price decision
San Diego's proximity to Tijuana means a slice of price-sensitive patients cross the border for cheaper dentistry. You're unlikely to beat that on price; you're more likely to win on trust, continuity, insurance, convenience, and emergency access. That reality should shape your messaging, your South Bay targeting, and which services you advertise.
