Justyna-5 star google review
Kasia was wonderful in helping our family. My husband had pulled something in his back a day before we were leaving for vacation and she was so quick in providing help and solutions. I know if any of my kids are sick, I can easily book a quick appointment with her. She’s smart and kind.

Frequently Asked Questions
What is a Nurse Practitioner, and can I receive primary care from an NP?

In Illinois, Nurse Practitioners with Full Practice Authority may practice independently and provide the same high-quality primary and preventive care as physicians.
