We Treat Kidney Diseases & Hypertension

We are a group of physicians specializing in Internal Medicine, Nephrology and Hypertension. We have extensive training to handle the comprehensive spectrum of diseases that can affect adults, no matter how common or complex. Our Nurse Practitioner specializes in Geriatrics and taking care of the elderly.

We are particularly focused on the diagnosis of kidney disease. Our focus is to educate our patients and caregivers so that they become full partners in their medical care. Our goal is to help the patient make changes in both lifestyle and medication to slow the progression of kidney disease. Once kidney disease has progressed, we offer a whole range off kidney replacement therapy, including transplantation, peritoneal dialysis, hemodialysis, home dialysis, and nighttime in center dialysis, to allow patients to continue their usual pre-dialysis lifestyle.
