About Dr. Sauer and Our Functional Medicine Team
Our Purpose Is:
Make Chronic Disease Optional
Dr. Sauer is a functional doctor based in Fargo, ND. Over his career in medicine, he’s seen many people rediscover their vitality and joy through holistic care. With every person, his goal is to listen closely and develop a personalized wellness plan for each person. It’s why he’s one of the region’s most trusted functional doctor.

I’m guessing you’re here wondering how to improve your health. It can be frustrating can’t it? The amount of information out there is, to put it simply… overwhelming. After struggling for years with depression, brain fog, moodiness, IBS, being overweight, fatigued and just overall not feeling motivated, I started transforming my health through lifestyle changes. That’s what led me to become a functional doctor in North Dakota.
It so radically transformed my life, that we coach and educate every one of our clients on those same methods (that took me YEARS to figure out). We condense it in a mere matter of months and give our members a very clear path on what to do and why.
After having success with hundreds of clients, and handling just about any kind of health condition and situation I would say we are pretty good at it. Today, we see clients across the country. People from Minnesota, North Dakota, Wyoming, Arizona, California, Wisconsin, Iowa, and Nebraska meet with our team online because they’ve seen the power of functional medicine. Our entire team is committed to helping you reach optimal health and vitality by treating your whole body.
The real question is… are YOU up for it?
Online appointments available.
Our team is dedicated to helping people just like you, succeed in finding their way back to health.
