Perlman Clinic operates one of San Diego's largest independent multispecialty primary care networks, and Kellie McAdams, PA anchors the pediatric panel at the Hillcrest location inside 3900 Fifth Avenue. Sick-visit overflow and urgent pediatric drop-ins route through the broader Perlman network including Perlman Clinic San Diego. McAdams handles well-child checks, CDC-schedule immunizations, school and sports physicals, ADHD screening, and adolescent reproductive health from a single pediatric panel. Pediatric dermatology cases resistant to first-line topical therapy — atopic eczema flares, infantile hemangiomas, molluscum contagiosum, and adolescent acne requiring systemic treatment — refer to Eichenfield Lawrence MD, the Rady Children's division chief practicing in the same Hillcrest corridor. Medication refills, prior authorizations, and insurance appeals run through a shared EMR that links all Perlman Clinic sites for continuity across vacation coverage. Multisystem pediatric workups layering failure to thrive, suspected endocrine disorders, and developmental delay escalate to Rady-affiliated subspecialty referrals coordinated directly from the Fifth Avenue panel.
