Marilyn Gregorowicz, PA-C

Marilyn has always been interested in medicine, science, and caring for others. She became a PA as a way to use her skills and interests to help people. She finds Neurology intriguing as the brain and the nerves are the control center that allow us able to experience life as we know it, feel emotions and pain, while automatically regulating our bodily functions to keep us alive. She enjoys being able to spend time discussing neurologic concerns, educating about diagnoses and medications, and discussing overall health so patients can have a better understanding of themselves and their condition. Outside of work she enjoys spending time with her husband, two cats, and dog. She enjoys being outdoors, working in her yard, and listening to good music.
