Synergy Rheumatology & Wellness in Carlsbad's Aviara corridor delivers board-certified rheumatology care from 6120 Paseo Del Norte, where the practice combines on-site infusion therapy, same-day musculoskeletal ultrasound, and active clinical research under one roof. The integrative autoimmune approach parallels functional medicine practitioners on this medical corridor, including Quantum Functional Medicine on El Camino Real. Triple board certification in Internal Medicine, Rheumatology, and Obesity Medicine follows a fellowship at the University of Wisconsin-Madison and internal medicine residency at Scripps Clinic/Green Hospital. As a California Rheumatology Alliance board member and principal investigator for active rheumatology clinical trials, the practice maintains research-grade protocols for biologic and DMARD management of rheumatoid arthritis, lupus, and Sjogren's syndrome — conditions often requiring coordinated infusion services through partners such as Infusion for Health - Carlsbad. Musculoskeletal ultrasound-guided joint aspirations and corticosteroid injections using high-frequency linear transducers allow real-time needle visualization for small-joint synovitis in the hands and feet.
