Founder & Registered Dietitian Nutritionist:

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

Circle Headshot.png

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.
