About us

Our Legacy

Over 50 years of compassion, innovation, and unwavering dedication to the kidney health of the Dayton community.

1972

The Foundation

Dr. Allen Feller founded Renal Physicians, planting the seed for nephrology care in the region by bringing life-saving dialysis treatments to Dayton for the first time.

The practice grew rapidly, becoming the largest nephrology group in the region by the early 2000s.

A New Standard

Dr. Larry Klein established Nephrology Associates of Dayton. Joined later by Dr. Mark Oxman, their tireless work ethic and commitment to patient care fueled incredible growth.

By the 2010s, the group had grown to equal prominence, serving thousands of patients across the Miami Valley.

Strategic Partnerships

Along the way, both groups partnered with industry leaders DaVita and Fresenius to provide comprehensive dialysis care, ranging from in-center hemodialysis to advanced home modalities.

Today, Dayton Kidney physicians are medical directors at dialysis units across the Miami Valley.

1970–2013

Transplant Legacy

Renal Physicians partnered with Miami Valley Hospital to provide life-saving kidney transplants until 2013, under the leadership of Dr. Augustus Eduafo, who served as transplant medical director.

Dayton Kidney physicians continue to work closely with regional transplant centers, including the University of Cincinnati and Ohio State University, to help our patients receive transplants.
