MEET DR. KATHIE WUELLNER, M.D.
Founder of Kids R Wonders
For the longest time growing up, I wanted to be a physician because the profession embodied helping others while using science.
I graduated from St. Louis University School of Medicine in 1978 and completed my Pediatric Residency in Chicago in 1981. After serving as Chief Resident, I discovered that beyond caring for children, I also truly loved teaching and guiding families through the many questions and uncertainties that come with parenting.
In 1983, after the birth of our first child, I established my own private pediatric practice in Alton, Illinois. While the practice has evolved over the years, I continue to own Pediatric Healthcare Unlimited and actively care for patients today.
But what has always brought me the greatest satisfaction is helping parents feel informed, reassured, and confident when caring for their children.
I believe parents deserve clear explanations, practical guidance, and an understanding of the “why” behind medical decisions, not just quick answers.
That is why I created Kids R Wonders.
Why I Chose Pediatrics
While medicine has been a huge part of my life, being a wife, mother, and now grandmother has shaped me just as much.
I have been married to my husband, Dr. John Wuellner, since 1978, and together we raised two children who both chose careers in medicine as well.
But before any titles or accomplishments, I was also a soccer mom, a school carpool driver, a parent volunteer, a fundraiser baker, and the mom putting band aids on scratches and comforting worried children.
I understand the emotions that come with parenting because I have lived them too - the worry, the exhaustion, the questions, and the deep desire to do what is best for your child.
My hope is that when you visit Kids R Wonders, you feel like you have a trusted pediatrician walking alongside you with calm, compassionate, and practical guidance every step of the way.
