About Katherine A. Zimmerman
About The Provider
Billings native Katy Zimmerman is back in Montana after completing her Masters in Nursing at Regis University in Denver, Colorado. Prior to becoming a nurse practitioner, Katy gained experience in medical surgical, hepatology (liver) and neurology settings. She is happy to be home and treating local families, where long-terms relationships can form over a lifespan of care.
"I am passionate about disease prevention and health promotion." Katy's philosophy of care is to partner with patients to address barriers to health, and to get to know them on a personal level to provide the best care possible.
To recharge, Katy loves anything outdoors. She enjoys running, hiking, camping, skiing and traveling. Especially with her golden retriever!

I enjoyed my appointment but find it disgusting that the IHS system requires its providers to use AI to listen in on private medical conversations. My NP Katy is a great provider who does not need to be babysat by a technology meant to replace what she does.

She’s listens and truly cares!

I’ve been a patient of Katy’s for a little over a year and had nothing but the best experience with her. She listens to how I’m feeling and is very helpful in recommending different ways we can approach my concerns. I appreciate that she gives different options rather than feeling like I only have one way to help my health.
