Kathleen O'Brien, MD practices dermatology in Encinitas at Scripps Clinic on Santa Fe Drive, holding American Board of Dermatology certification and a Georgetown University School of Medicine degree. Her medical dermatology scope treats both adults and children for conditions ranging from skin cancer and acne to psoriasis and atopic dermatitis, a pediatric overlap that aligns with the referral network serving Children's Primary Care Medical Group in the same Encinitas medical community. Affiliated with Scripps Memorial Hospital Encinitas, she performs outpatient surgery for cancerous and non-cancerous diseases of the skin on Santa Fe Drive near Encinitas Community Park. Her clinical approach integrates nutritional and environmental exposure analysis with standard dermatologic treatment, examining how diet, exercise, and systemic illness manifest in skin conditions. Post-surgical wound recovery and scar-management protocols for complex excision patients benefit from the rehabilitation services at PRN Physical Therapy in the Encinitas recovery network. Highest-tier services include surgical excision of keloids, complex cyst removal, and biopsy-guided treatment planning for inflammatory dermatoses refractory to first-line topical corticosteroid therapy.
