We know how you feel because we've been there.

We have dealt with our own gut issues, and now we want to help guide you to experience relief.

We've had clients tell us that our guidance has changed their life. That's why we continue to do what we do.

Our goal is to go above and beyond to help you reach your goals. We want to save you time (with our easy to use app!) and provide you with functional nutrition care that you likely have not been receiving in the current medical system. 

Together, we have 17+ years of formal schooling in nutrition science (plus all the conferences and continuing education), with experience guiding clients to improve a wide range of health issues, including IBS, Crohn's, UC, SIBO, food sensitivities, autoimmune issues, and more.


We want you to get back to doing what you love, without gut issues getting in your way, whether that means raising a child, playing with your grandchildren, going on that hiking trip with your friends, having more flexibility in job options, getting to travel on a whim, and more! By working with us, we promise to do what we can to help you feel your best.

Ashley Circle.png


Registered Dietitian & Founder


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, studying a variety of topics, and spending time with the people she meets along the way.

Ashley is not taking new clients at this time.
