Why Choose Viva Rheumatology

Three reasons patients trust us with their autoimmune care

Expert, Board-Certified Care

Our physicians bring over 45 years of combined rheumatology experience. Dr. Zhaz-Leitner is double-board-certified in rheumatology and internal medicine, while Dr. Kowal has dedicated over three decades to treating autoimmune diseases. Both are fellowship-trained specialists who stay current with the latest treatments through active participation in leading medical organizations.

Comprehensive Treatment Approach

We treat the full spectrum of autoimmune and inflammatory conditions, including rheumatoid arthritis, psoriatic arthritis, lupus, giant cell arteritis, and vasculitis. Viva Rheumatoloy’s doctors take time to understand your unique symptoms and develop personalized treatment plans that address not just your condition, but your quality of life.

Personalized, Accessible Care

Communication matters. Dr. Zhaz-Leitner speaks English, Spanish, and Cantonese, ensuring clear understanding with patients. Viva Rheumatology combines the expertise of academic medicine with the personal attention of a community-focused practice, where you’re treated as an individual, not just a diagnosis.
