Founder & Registered Dietitian Nutritionist:

Ashley Oswald, RDN, IFNCP, CNSC, CLT, LD

Ashley has completed training from Harvard's Brigham and Women's Hospital, the University of Minnesota, and the Integrative and Functional Nutrition Academy (7 years of formal education in nutrition science). 

Her passion for digestive health stems from her own journey using functional nutrition (food and lifestyle medicine) to recover from severe acne, years of antibiotic use, Irritable Bowel Syndrome, brain fog, fatigue, major depression, and Hashimoto's thyroid disease. Digestion truly is at the center of health, and can affect other organs if not cared for properly. 

Ashley has great empathy for people. She is futuristic in her vision, has an easy time gathering information, is a high achiever, and values making connections. All of these traits have allowed her to create a clinic where people are the priority, and providing the best digestive health nutrition care world-wide is the goal.


She values freedom for herself personally, for her team, and for the clinic clients. Freedom in the way of time flexibility. Freedom in the way of getting rid of bothersome digestive symptoms. Freedom in the way of getting to live each and every one of our life's purposes to the utmost ability. She is a great mentor to other dietitians, and is often come to for nutrition answers and advice. Her minimalistic and organized nature allows her to quickly pull knowledge from her seemingly bottomless electronic files of notes, research studies, and handouts. This ability is one that is at the core of Oswald Digestive Clinics success in helping people improve their symptoms and quality of life. 

Ultimately, she is passionate about empowering others with the knowledge and tools needed to take charge of their own health, in return relying less on the medical system.


Outside of the clinic, you can find Ashley kayaking, practicing kundalini or vinyasa yoga, biking, enjoying live music, traveling, or simply spending time with friends / family / community.

Nutrition Intern: Kate Walcheck

Kate is a student at the University of Minnesota, Twin-cities. She is currently a Junior, studying Nutrition and Dietetics, with the goal of completing her dietetic internship and becoming a Registered Dietitian-Nutritionist. She was excited to become of member of the clinic's team, as Kate’s role combines two of her great passions: nutrition and creativity. 


Her interest nutrition began in cross country during high school, when Kate realized healthy eating helped her endurance and speed. But a trip to FNCE, a food and nutrition expo in Washington DC, sparked Kate’s realization that she wanted to become a dietitian. At FNCE, Kate attended a weekend full of seminars on new, relevant nutrition research, as well as common dietary misconceptions. This gave Kate a deeper appreciation and curiosity towards the important connection between food and long-term health.


When Kate isn’t studying, you will likely catch her running alongside the Mississippi River, trying out brunch spots in the cities, experimenting with new healthy recipes, or finding every opportunity to hike, paddle board, cliff jump, and soak up Minnesota’s few months of sun.
