About Us
The International Kidney Vasculitis and Glomerular Center (IKVGC) is part of Nephrology Associates of Northern Virginia. Dr. Reza Zonozi is dedicated to the diagnosis, treatment, and long-term management of glomerular diseases and vasculitis affecting the kidneys. As a specialty referral center, we provide expert care for patients with rare and complex glomerular disorders.
The center is titled “International” in tribute to Dr. Zonozi’s father, Dr. Meersaiid Zonozi, whose dialysis clinic bore the same name, and as a reflection of the multicultural staff and diverse community of patients we proudly serve - both from the Washington, D.C. metropolitan area and around the world.
With a commitment to clinical excellence and compassionate care, IKVGC is here to serve as a referral hub and long-term partner for patients navigating the complexities of autoimmune kidney disease.
We care for a wide spectrum of conditions, including:
ANCA vasculitis, including granulomatosis with polyangiitis (GPA; formerly known as Wegener’s Granulomatosis), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA; formerly known as Churg-Strauss Syndrome), and renal-limited vasculitis.
IgA vasculitis and IgA nephropathy
Anti-glomerular basement membrane disease (also known as Goodpasture’s Disease)
Cryoglobulinemic vasculitis
Lupus nephritis
Membranoproliferative glomerulonephritis (MPGN) and C3 glomerulopathy
Thrombotic microangiopathies, including atypical hemolytic uremic syndrome (aHUS)
Membranous nephropathy
Minimal change disease (MCD)
Focal segmental glomerulosclerosis (FSGS)
Monoclonal gammopathy of renal significance (MGRS)
Fibrillary glomerulonephritis

About Dr. Zonozi
Dr. Reza Zonozi is a board-certified nephrologist and director of the International Kidney Vasculitis and Glomerular Center (IKVGC). He earned his medical degree from Georgetown University School of Medicine. He completed his internship and residency in internal medicine at The Johns Hopkins Hospital in Baltimore, followed by fellowship training in nephrology at the Brigham and Women’s Hospital and the Massachusetts General Hospital in Boston. He subsequently served as an attending nephrologist at MGH and promoted to Assistant Professor of Medicine at Harvard Medical School. He moved to Virginia in 2023 to join Nephrology Associates of Northern Virginia and start the IKVGC.
His clinical research has focused on optimizing treatments for autoimmune kidney disease, with contributions to multiple clinical trials investigating novel therapies such as avacopan and rituximab-based regimens. His work has been published in Science Translational Medicine, Annals of the Rheumatic Diseases, and American Journal of Kidney Diseases, and he was honored with the Young Investigator Award at the International ANCA Vasculitis Workshop in Dublin, Ireland.
Throughout his career, Dr. Zonozi has been deeply influenced by the mentorship of his father, Dr. Meersaiid Zonozi, a respected nephrologist in the Washington, D.C. area, and Dr. John Niles, a global clinical expert in ANCA vasculitis. Their guidance has shaped his clinical approach.
He remains active in medical education, having taught and mentored nephrology fellows and internal medicine residents at Harvard, Johns Hopkins, and Inova. He is fluent in Spanish and Persian, which helps him provide more inclusive and accessible care to a diverse patient population.
