Our History

Drs. Robert A. Pflederer and R. Kent Bryan co-founded RenalCare Associates in 1975. Over the years, this group of nephrology professionals gained even greater expertise through the addition of a Board-certified transplant surgeon (Dr. O'Connor), 17 Board-certified nephrologists, and seven physicians with certification from the American Heart Association (Dr. AlonsoDr. JacobDr. KhattakDr. RosboroughDr. SparrowDr. R. AllaDr. S.Alla, and one Physician Assistant, Holly Walker).* Our team also expanded to include a physician assistant, ten family nurse practitioners, and an adult health clinical nurse specialist, as well as an executive administrator and director of operations.

RenalCare Associates offers consultations with other physicians to help them gain a deeper understanding of our nephrology care services.

*Note: The Certified Specialists program was introduced by the American Heart Association as part of a coordinated effort to efficiently manage hypertension and health problems related to this condition. Specialists who are given this designation have been recognized as having knowledge, skills and expertise in managing clinical hypertension and related disorders. These specialists are able to serve as consultants for complex cases and provide guidance and advice on guidelines for hypertension management.

What Patients Are Saying

"Dr Tim Pflederer.....He is beyond very smart and up to date on cutting edge medical treatment, but he has a compassion and empathy not often found in specialists especially. He always takes the time to listen and do what is needed. I have been a patient of this group for over thirty years and he is above all the best doctor I have ever seen. If you have the good fortune to get Dr. Tim, your are fortunate indeed as all that can be done will be done, he is that good, without question."

"Dr. Jacob is more than a doctor she is a person that has compassion and care for others. My brother was critically ill and in the ICU at OSF. She explained to my family in the utmost compassion about his outcome. The news was not good but I will be eternally grateful that she was able to get my dad to calm down and understand. Please keep doing what you do and I hope that others will follow the example that you are".

"Dr. Rosborough is very straight forward and to the point. He is very competent and explains things to me. I appreciate the directness of his care."
