The group continued to grow and by 1998 when it became Renal Associates there were 6 physician partners.
In 2002 Renal Associates opened a Vascular Access Center to provide vascular access care and maintenance to patients receiving dialysis. Having a well-maintained vascular access provides good blood flow during hemodialysis. Renal Associates was then able to treat patients at the access center instead of sending them to the hospital for delayed care. The expedient and quality care provided by the Vascular Access Center served as a model for other nephrology groups across the nation.
