There is Hope for Healing

Have you or a loved one been struggling with chronic migraines? Maybe you have tried medications, invasive treatments, and even ended up at the ER in order to manage your pain. Do you feel like you’ve hit a dead end and don’t know what to do next?

Unfortunately, this experience is all too common and something we have personally struggled with as we sought to restore our own health. That’s why we feel a responsibility to share our hope for healing and help you in the process.

Our dedication to helping you is best summarized by a quote from Nobel Laureate Albert Schweitzer: “Those who bear the mark of pain are never totally free, for they owe a debt to those who suffer”. 

This hope comes from our personal experience healing chronic migraines, experience working with clients who have made lifestyle changes to allow their bodies to balance and get rid of chronic migraines, and clinical training in the functional medicine approach to nutrition, which provides the scientific understanding as to why dis-ease occurs and the steps to take in order to restore healthy functioning of the body.

When you partner with us, we dig beneath the surface to understand what imbalances in your body may have triggered your health challenges, how to best support your body in the healing process, and create a personalized functional nutrition and lifestyle plan to help you achieve your health goals. You are an active participant in the process as we support you along the way.

Frequently Asked Questions

Learn How it Works

How is Our approach unique?

Our approach combines the holistic healing therapies of both Functional Nutrition & The Gerson Therapy. We view the body as a whole system and explore options to balance these interconnected pathways in order to restore health. This approach moves beyond addressing symptoms with pharmaceuticals and instead focuses on investigating why and how illness occurred, followed by therapeutic interventions to restore balance within your body.

What Happens During the Initial Functional Nutrition Session?

Prior to your initial session, you will be asked to complete and return a detailed health history, including an overview of your current symptoms and recent dietary intake. These forms are completed via an online portal called Practice Better and then reviewed during the initial session. During the initial 60-minute appointment, we dive into your health history, investigate the root causes of your illness, and determine your next steps. After the initial session, a personalized nutrition and lifestyle plan will be created for you and will be discussed during your 30-minute follow up session, which is included in the initial session fee. 

What should I expect during a follow up session?

Follow-up sessions are 30 minutes in duration and occur after your initial session. During this time, we review your personalized dietary and lifestyle plan and create next steps to ensure your success in your healing journey. These sessions are also a time to review your progress, address any new challenges, provide you support and education, and review any updates from your primary healthcare provider. 

Cancellation Policy

If you need to reschedule our appointment, please give us 2 days/48 hours notice.
