Pen Bay’s Nephrology Clinic is for people with kidney conditions and/or hypertension. Early kidney disease produces few symptoms, therefore it can often go unrecognized. Kidney disease is frequently associated with diabetes, hypertension, cardiac and obstructive urological conditions. Patients are able to consult with Dr. Vannorsdall to learn more about the management of their kidney condition and related medication issues.
