Nephrology & Endocrinology Healthcare Services - Southwestern PA

Partners In Nephrology & Endocrinology (PINE) uses the latest technology and care available to treat and support those living with illnesses related to poor kidney function and/or thyroid hormone imbalances. We are particularly focused on providing treatments to patients with diabetes, chronic kidney disease, thyroid disease, and/or hypertension (a.k.a. high blood pressure).

Our practice focuses on these ailments due to their strong connections: diabetes raises the risk of kidney problems, kidney problems raise the risk of hypertension (and vice versa), and chronic kidney disease often presents alongside certain thyroid diseases. It's a powerful reminder of the link shared by the practices of nephrology and endocrinology. By working together, our team members - who have backgrounds in both specialties - can help patients of all ages address their interconnecting health needs thoroughly, effectively, and compassionately.

Our practice has been at the forefront of the treatment and management of kidney and endocrine diseases for more than 35 years, and is the western Pennsylvania region’s most recognized and experienced nephrology and endocrinology group. We invite you to contact us at a location convenient to you, and to include us in your care journey.
