Testimonials
I found Katie through—Chicago Cold Club. All I needed was a Saturday’s breathwork and plunge with her to know this was the energy and instruction I wanted to start Pilates with. I admit I was skeptical about starting Pilates online, but within one session I forgot all about it. Katie notices every detail and provides great cues, so you know you are doing each move correctly. She’s so encouraging, positive and joyful!

IOut of everything I’ve done to improve my stress levels, daily breathwork with Katie has made the biggest impact. Her classes help me feel grounded before my kids wake up and as a result I’m so much more tolerant and patient with them in the morning. Along with being an expert in her field, Katie is a focused, knowledgeable, intuitive and just overall wonderful coach and guide. She shows up to class prepared, enthusiastic, and full of love and humor. Working with her has been truly transformational!

I am so pleased with Katie's virtual Pilates class. I have chronic knee pain and Katie has designed a custom Pilates course which is improving my range of motion. She has also taught me a meditation which assists in managing my knee pain. Katie's anatomical knowledge is amazing! If you are looking for a 5 star Pilates coach with a deep spiritual base, Katie is your teacher!
