Marissa Walczak is a nurse practitioner specializing in nephrology. She sees patients with chronic kidney disease and kidney failure, and helps to monitor dialysis and kidney regulation.

Walczak worked as a registered nurse for more than 15 years and found she was very passionate in building relationships with her patients.

Walczak earned her Master of Science in Nursing degree at Walsh University in North Canton, Ohio and her bachelor's degree in nursing at the University of Wisconsin-Eau Claire.
