University Nephrologists specialize in the management of patients with end-stage renal disease, pre- and postoperative care of kidney tranplant patients, and immunosuppressive therapy. Our nephrologists collaborate with transplant surgeons, cardiologists, dietitians, social workers and other specialists to carefully evaluate and manage transplant candidates, recipients and living donors.


Vasil Peev, MD, is board certified in Nephrology and Internal Medicine. He completed medical school at the University of Heidelberg Medical Faculty, Germany, and his residency and fellowship at the University of Miami Jackson Memorial Medical Center. Dr. Peev has clinical expertise in kidney disease and kidney transplant. Additionally, he is an Assistant Professor in the Department of Internal Medicine at Rush Medical College and is fluent in five languages (English, German, Macedonian, Serbian, and Spanish.

Dr. Saltzberg is board certified in Internal Medicine and Nephrology and has clinical expertise in kidney disease, kidney stones, and kidney transplant.


​Haimanot (Monnie) Wasse, MD, MPH, is professor and vice chairperson in the Department of Internal Medicine. She is also the director of interventional nephrology, a new program she brings to Rush. A distinguished physician, scientist and professor for nearly 15 years, Dr. Wasse most recently directed the interventional nephrology program and was an associate professor of medicine at Northwestern University Feinberg School of Medicine. She previously headed interventional nephrology at Emory University School of Medicine in Atlanta. She is board-certified in nephrology and interventional nephrology.

Dr. Wasse’s mission at Rush is to bring Chicago-area kidney disease patients the highest standard of comprehensive vascular access care; to prepare clinicians to provide patient-centered vascular access care; and identify and address the causes, prevention and treatment of vascular access dysfunction.

At Rush, Dr. Wasse’s research will focus on the predictors, consequences and treatment of arteriovenous access dysfunction. She seeks to characterize the key mechanisms, pathways and genes involved in dialysis access dysfunction, particularly in the high-risk African-American population and to establish a comprehensive vascular access database and biologic specimen biobank. Her previous work, as principal investigator of studies funded by the National Institutes of Health, the Robert Wood Johnson Foundation and other institutions, paves the way for these efforts.

Dr. Wasse is president-elect of the American Society of Diagnostic and Interventional Nephrology and serves in other executive positions for professional societies nationally. A dedicated educator, she has intensively mentored and taught numerous fellows, residents and medical students, and will continue to do so at Rush.
