About Regan Seipp, MD

Philosophy of Care

Modern medical care, especially Nephrology, is often characterized by unfamiliar terms, perplexing laboratory data and a sense of disconnection. By developing strong patient relationships, I strive to demystify kidney disease and provide current, evidence-based care aimed not only for the health of the kidneys, but of the whole person.

Dr. Siepp is literally the most amazing physician I have ever seen, and I have seen a lot of doctors in my life. He had a remarkable approach and bedside manner. He was thoroughly informed about my medical history, explained how I should approach further treatment, asked me if I had questions he could answer before he began explaining my situation, and was highly supportive, knowledgeable, and engaged. I can't say enough wonderful things about my experience with Dr. Siepp. I went home and told my family and friends all about my amazing experience at this appointment. I wish I could see him for all of my medical needs. He is truly incredible!!!
