At Comprehensive Rheumatology Center, we believe every patient deserves care that treats the whole person — not just the diagnosis. Located at 23067 Ventura Blvd, Suite 200 in Woodland Hills, CA, we proudly serve patients throughout the West San Fernando Valley and Conejo Valley.

Our care team brings together four dedicated providers who share a common goal: helping patients with complex autoimmune and inflammatory conditions live fuller, more comfortable lives. Nazanin Firooz, MD, FACR, is a board-certified rheumatologist and founder of our practice, known for her expertise in integrative and holistic rheumatology. She is joined by Phillip Aleksiejuk, MD, a board-certified rheumatologist with a thorough, patient-centered approach; Rana Taherian, MD, a board-certified rheumatologist who brings a wealth of experience and dedication to personalized care; and Sabrina Roofian, PA-C, whose warmth and attentiveness make every patient feel heard and supported.

We specialize in rheumatoid arthritis, lupus, psoriatic arthritis, ankylosing spondylitis, gout, fibromyalgia, and more. Our on-site infusion suite offers biologic IV therapies, and our integrative approach blends conventional rheumatology with holistic treatments tailored to each patient.

We accept most major insurance plans and welcome both referred and self-referred patients. Call us at (818) 598-0000 — we’d love to help.
