26 million American adults have kidney disease… and most don’t know it.

Nephrology specialists at Pentucket Medical bring not only their expertise to the treatment of kidney diseases, but also the attitude that you, the patient, deserve the very best. Effective treatment of multi-faceted diseases like electrolyte disorders, hypertension, and end-stage renal disease require a team approach.

Your nephrology specialist understands that your Primary Care Clinician plays a key role in managing your health concerns and with our integrated System of Care, your nephrologist is in constant contact with your Primary Care Clinician. Our Electronic Medical Record allows those who are caring for you to have consistently accurate, current health information for you.

Pentucket Medical recognizes that it can be scary when you’re facing something as complicated as kidney disease. There is much that can be done to preserve kidney function and prevent problems if we all work together and take the right steps to prevent complications.
