Primary Care as the Hub
Primary care physicians in San Diego are the starting point for most specialist referrals. Family medicine and internal medicine providers generate the highest outbound referral volume. If you are a specialist in San Diego, your growth strategy should start with PCP relationships.

Mental health providers cross-refer between therapists and psychiatrists. These bidirectional relationships are often the most valuable because both sides benefit directly.
