Peggy Tsevis, RD

Hello! As your personal dietitian, my goal is to make nutrition feel less complicated and more like a lifestyle. I have over 25 years of nutrition experience and have counseled thousands of patients to-date, providing personalized nutrition recommendations in a relaxed and comfortable style. I have spent a large portion of my career in the ob/gyne space but have also worked with many male clients, as our office employs a functional medicine doctor that treats both men and women.

​

In addition to being an Registered and Licensed Dietitian, I am also a Certified LEAP therapist, which means I specialize in food sensitivity testing. I utilize a patented blood test called MRT (Mediator Release Testing) to help identify your unique set of foods that may be contributing to symptoms of IBS(constipation, diarrhea, or both), GERD, migraine headaches, joint/muscle pain, eczema/psoriasis, chronic sinusitis, and other inflammatory or autoimmune conditions. Together with your blood results, we will create a personalized elimination diet to help reduce your symptoms by as much as 50% in as little as 2 weeks. As you continue with your custom elimination diet over a period of 6-8 weeks, we check in via symptom surveys to help monitor your progress and review how to best expand your diet.

​

I am also trained in ordering and interpreting GI Map testing, a stool test which provides a big picture overview of your gut microbiome's health. This can help us detect what may be upsetting your normal microbial balance as well as give us a snapshot of your digestion, absorption, inflammation, and immune health. Based on your results, we will collaborate on a care plan for you to follow over a 3-6 month period, which will include carefully curated supplements and dietary guidelines based on your stool test analysis.

​

I hold a Master's degree in Public Health from the University of Illinois at Chicago, graduating magna cum laude, and I double majored in biology and psychology as an undergrad at Loyola University, graduating cum laude. I am married and the mother of 2 young adults. I love spending time with friends, warm weather, outdoor walks, traveling, and getting to a beach as often as possible!
