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. 

Licensed dietitian nutritionists on average, have 7 years of formal schooling in nutrition science (plus all the conferences and continuing education), and our team has education beyond this in functional nutrition, 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 are a 100% functional nutrition clinic, committed to providing the best quality holistic nutrition care to help you finally improve and eliminate those gut issues to feel your best! 


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

Gut Health Dietitian Nutritionist & 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 system 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.

Katie Circle Headshot.png

Gut Health Dietitian Nutritionist


Katie received her Master's Degree in Human Nutrition from Eastern Michigan University, her Undergraduate Degree in Food Science and Human Nutrition from the University of Maine, and completed her dietetic internship with 1,200 hours of supervised practice in Tennessee. Since then, she has gone on to complete a certification in Functional Nutrition from the Functional Nutrition Alliance, which included an in depth study of the digestive, immune, urinary, cardiovascular, endocrine, nervous, and reproductive systems, all through a functional and holistic medicine lens, with many hours of case study practice.

Katie has been a dietitian now for almost a decade, and during much of this time, she worked as an inpatient hospital and outpatient clinic dietitian, helping a variety of clients to feel better and achieve their goals.

Through her own struggle with chronic fatigue, iron deficiency, mold toxicity, and recurrent mono - which conventional medicine did not have the tools to help her with - Katie came to realize that she wanted to work in a setting that allowed her more flexibility to help clients fully, in the ways she has seen to be effective: by using a holistic / functional / root-cause medical nutrition therapy approach.

So, she left the hospital setting to have her twin babies. During this time, she helped family and friends with their health, and ended up using her knowledge to help her own babies, too, after her infant son started to struggle with severe eczema, food allergies, poor gut health, and sleep disturbances. 

Now that her babies are no longer infants, she is ready to start seeing clients again, and we are so thrilled to have her on board with our clinic. Katie is excited about empowering and supporting her clients to realize how powerful functional nutrition can be, to support their body's own innate ability to heal when given the right tools and support.

Outside of the clinic, Katie loves to cook and bake, to learn and discover new things, to travel and experience new places, and, especially now, loves to spend time at home with her husband and young twins.

Gut Health Dietitian Nutritionist


Megan studied dietetics at Michigan State University and completed her masters and internship at Grand Valley State University.


After finishing her education and working in various clinical settings, she quickly developed a love for gut health nutrition, in part due to her own gut health struggles and seeing the gaps in conventional care. 

Megan then dove deep into study with the Integrative and Functional Nutrition Academy alongside self study, and began working with a wide array of gastrointestinal conditions. 

She specializes in working with clients who have chronic gut health issues and those looking to heal their gut-brain axis for conditions like IBS, IBD, poor gut health from yo-yo dieting, chronic bloating, reflux, and more. 

Her nutrition philosophy centers around the idea that the gut thrives on abundance rather than restriction, and together with her clients, she helps them to find a balance with their diet that is sustainable long term. 

She also believes our mindset around food and nutrition it just as important. Her emphasis on healing the relationship with food, helps her clients develop ease around nutrition choices, rather than add to their anxiety.

Outside of the clinic, Megan loves to cook and develop recipes. She also is a big singer, knitter, reader, and gardener, and you can find her exploring new ways to enjoy the outdoors and embracing the seasons here in the midwest.
