About Katarzyna (Kasia) Szerlag, MSN, FNP-BC
Katarzyna “Kasia” Szerlag was born and raised in Poland before moving to the United States as a teenager. Her passion for nursing and medicine began in high school when a family member’s illness brought her into the hospital setting — an experience that inspired her to dedicate her life to caring for others.
After high school, Kasia began her healthcare career as a nursing assistant at Lutheran General Hospital while earning her Bachelor of Science in Nursing from West Suburban College of Nursing in Oak Park, Illinois, graduating in 2009. She then spent several years working as an emergency room and trauma nurse at Lutheran General Hospital in Park Ridge, where she developed strong clinical skills and a deep commitment to patient care.
Motivated to expand her role in healthcare, Kasia pursued her Master of Science in Nursing and graduated as a Family Nurse Practitioner from the University of Illinois at Chicago in 2016. She is board-certified by the American Nurses Credentialing Center (ANCC) and, in 2019, obtained full practice authority in Illinois, allowing her to serve patients as an independent provider.
Kasia’s practice is centered on lifestyle medicine, urgent care, and wellness coaching. She is passionate about building healthy habits, promoting long-term wellness, and supporting patients in achieving their personal health goals. Whether you’re working on short-term improvements or making meaningful long-term changes, Kasia is committed to guiding and encouraging you every step of the way. She is also currently pursuing additional certification as a wellness health coach to further support her patients’ journeys.
Outside of work, Kasia enjoys spending time with her husband, their two young daughters, and their beloved dog, Misiu. She stays active with Peloton rides, Pure Barre classes, and nature walks, and she loves traveling, exploring new cultures, and trying new cuisines.
