After a 10-year struggle with anorexia, lifelong chronic and complex digestive issues, infertility, and the birth of her twins, Marcie realized that throughout her experiences, nutrition was her saving grace, and she knew she needed to share what she whole-heartedly believed in to help change the lives of others.

Marcie is a firm believer in educating her clients to make dietary changes that can help them lead the life they desire.

Outside of helping to guide her clients back to health, Marcie enjoys watching her twins compete in sports, being creative in the kitchen, and decorating her home. She also loves running, weightlifting, and spending days at the lake or winter evenings all snuggled in with her favorite people.

5 Fun Questions To Get To Know Marcie Better:

Ashley Circle.png




Ashley graduated from her dietetic internship at Boston Harvard's Brigham and Women's Hospital, and pursued continuing education in functional medicine from the Integrative And Functional Nutrition Academy.

In 2016, after working as a dietitian in a variety of settings from Intensive Care Units, to specializing in IV nutrition in California, and eventually landing at a MD-ran private practice in California, a personal change pushed her to move back to Minnesota, where she decided to start Oswald Digestive Clinic. 

She had a unique vision for the clinic, though. She wanted to fill the gaps in the healthcare system... and do it better. At the start, Ashley saw her clients via home visit. Eventually, she got too busy to be making the trips, so she transitioned to telemedicine, at a time before telemedicine was popular. Then, she decided to purchase an electronic health record that provided an easy app for clients to use. No more having to tediously track meals eaten, because now her clients could simply take a photo using the app!

Fast forward to today, and we now take insurance (due to COVID, insurances started to cover telemedicine!), meaning our clinic is more accessible, allowing our team to grow and help more people improve their gut health using a root cause approach! We are so grateful for all of our clients who choose our clinic to work with, and all of you who refer to us.

Outside of the clinic, Ashley can often be found in nature, traveling or exploring her surroundings, and studying a variety of topics from learning languages like Farsi to Quantum Physics.

Ashley is not taking clients at this time.
