Leslie Stiles is a Registered Dietitian and Board Certified Specialist in Pediatric Nutrition. She graduated from the University of Illinois at Chicago with a Master’s degree in Nutrition in 2011. As a student she received additional training through the Illinois Leadership Education in Neurodevelopmental Disabilities Program where she worked with children with autism and special healthcare needs. She also completed a pediatric nutrition fellowship program through Indiana University in 2012.

After graduation, Leslie worked at Ann & Robert H. Lurie Children’s Hospital of Chicago as a clinical dietitian in the Allergy & Immunology Department as well as the Genetics Department. Through her clinical work, Leslie became familiar with the struggle many families face to provide nutritious and balanced meals – especially those affected by food allergies.

She loves the challenge and creativity involved in planning wholesome meals and snacks on restrictive diets. Leslie is passionate about the power of nutrition and the family meal, and she enjoys working with families or individuals in all situations to make better nutrition achievable.   

Leslie’s professional expertise and interests include working with children and adults with food allergies and food sensitivities, children who are picky or selective eaters, children and adults with autism or developmental disabilities, children and adults who are underweight or overweight, those who are tube-fed and families who just want to eat better.

When Leslie is not working she enjoys time with her young son and daughter, cooking meals with friends and family, reading, and discovering new music.

We are delighted to be able to offer dietician services to our patients whether they may need them for food allergies concerns, or for general health and nutrition, as part of our holistic philosophy of care.
