Treating Thyroid & Adrenal Disorders



Thyroid and adrenal disorders often fly under the radar, but they can cause a range of symptoms people commonly describe as just “feeling a little unwell.” That means could be a medical explanation for your tiredness, forgetfulness, and depression. Let’s start reclaiming your health.

The thyroid gland is located inside your neck, while your adrenal glands sit at the top of your kidneys, so it would be easy to think they’re unrelated. The truth is they both create hormones, which act as chemical messengers designed to help your body function as it should.

If they start producing too much or too little, they can cause serious issues that significantly affect your vitality and quality of life. This can affect everything from your energy levels to your skin, mood, digestion, and more. In many cases, lifestyle changes and supplements can make a big difference. That’s why functional medicine is important. We’ll work with you to assess whether your glands are functioning properly and what we can do to get them back on track to restore your health.

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.
