Meet Team NNH

Kidney care is personal. So is our team.

The people behind your care

At Northern Nephrology & Hypertension, our patients are cared for by a close-knit team that works together across the office, infusion center, dialysis units, and kidney education programs. Get to know some of the people who help make that care possible.

How we work together

One Team. Many Parts of Your Care.

Good kidney care is much more than the minutes you spend with a provider in the exam room. Tap a step to see who's involved.

It starts with a phone call or a referral. Our front-desk and office team schedules your appointment, gathers your records, checks you in, and rooms you so your provider has what they need before they walk in.

Who you'll meet: the front desk and office team, and our medical assistants.

Your provider reviews your labs, blood pressure and history, explains what the numbers mean, and builds a plan with you. Between visits, the team tracks results and follows up so nothing slips through the cracks.

Who you'll meet: your nephrology provider and the clinical staff who support your visit.

When you need more than a routine visit, the same team is still with you: infusion treatments in our office, kidney education classes, planning for dialysis or transplant, and coordination with the dialysis units.

Who you'll meet: our infusion nurses, educators and providers, working alongside the office team.

A lot of kidney care happens when you're not in the building: getting medications approved by your insurance, sending records to other doctors, returning calls, and keeping the practice up to state and federal standards.

Who you'll meet: usually by phone — our office, billing and compliance team.

Who we are

Small Team. Big Commitment.

Northern Nephrology & Hypertension has cared for patients across northern New York for years. We're a small practice on purpose: our team works closely together so you can get coordinated kidney care close to home, from people who know your name.

Ready to meet us?

Whether you're coming in for your first kidney evaluation or have been part of the NNH family for years, we're here to help.
