Treating Autoimmune diseases



Autoimmune diseases are complex, chronic illnesses that can have a number of triggers. They can explain a series of seemingly unlinked symptoms, such as fatigue, joint pain, swelling, skin problems, abdominal pain, digestive issues, inflammation, and more. Let’s find answers.

Autoimmune diseases occur when the immune system starts mistakenly attacking healthy cells. This can cause a range of chronic symptoms that can significantly diminish your quality of life.

If you’ve already tried a traditional treatment approach, you’ll very likely have been prescribed medication to suppress your immune system and mask the symptoms. However, as you probably already know, this can lead to a range of other issues. When you choose a functional medicine approach, we will work with you to identify the triggers, help your body understand the difference between healthy and unhealthy cells, and start reversing the process of autoimmunity.

We’re not here to put a band-aid on the problem, we’re here to help you live a healthy and happy life for many years to come. It’s time to take control and start living the life you want.

Where are you located?

Can you work with me?

Our main office is in Great Falls, Montana, but we are able to work with individuals nationally and internationally thanks to HIPAA compliant telehealth.

Telehealth — sometimes called telemedicine — lets you visit your doctor and receive care without an in-person office visit. Telehealth is done primarily online with internet access on your computer, tablet, or smartphone through video conferences and internet phone calls. This remote option is ideal for people who live in remote areas, or need consultation with a specialist whose office is an unreasonable or burdensome distance away. If you have internet access, we can help.
