Global Nephrology Solutions Expands Leadership Team with Key Hires and Broadens Network with Addition of Four Practices

Key hires position company for further growth and expansion

TEMPE, Ariz.–(BUSINESS WIRE)–Global Nephrology Solutions (“GNS”), one of the largest physician-led and physician-owned kidney care platforms in the United States, announced the addition of six senior executives to the rapidly growing organization.

The expanded leadership team will accelerate the scaling of the company’s best-in-class kidney care delivery platform that puts nephrologists and patients at the center of care. In January 2021, GNS announced a partnership with Audax Private Equity (“Audax”) when the platform included more than 315 providers and 700 employees providing the complete continuum of kidney care across 10 states to over 170,000 patients. The GNS value-based care delivery platform is driven by proprietary, predictive data analytics and clinical workflows underpinned by one of the world’s largest clinical chronic kidney disease (“CKD”) data warehouses that enables nephrologists to deliver better patient outcomes and value-based care. Building on its deep value-based experience with and participation in CMMI ESCO models, on January 1, 2022, GNS will launch CKCC value-based operations in four markets with over 10,000 covered lives, representing over $600 million of medical expense under management.

Since onboarding the new team, GNS has quickly moved to expand its operations in existing markets by adding four new practices across Florida, Texas, and California, bringing the total number of providers to over 350. The four new practices serve over 20,000 patients.

The organization seeks to rapidly grow its reach in the next 12 months to advance its pursuit of the quadruple aim of delivering cost-effective care, improving patient outcomes, and enhancing both the patient and physician experience. “Our platform is being validated by nephrologists in the market. We have a very robust pipeline of practices in new and existing markets that want to join our nephrologist-led platform. With new leadership team members in place, we are increasingly able to forge partnerships and integrate these practices and serve our growing platform,” said Rajiv Poduval, MD, FASN, Founding Chief Executive Officer of Global Nephrology Solutions.
