Nutrition Therapy
The ‘gut’ is often considered the second brain. The more you nourish your body, the more efficiently your brain will function.
The latest neurofeedback technology
We provide our clients state of the art sessions via NeurOptimal®, a 5th generation Neurofeedback solution. It is effective, holistic and non-invasive. Using neural signals based upon your own brain’s activity, NeurOptimal® stimulates your brain to self-adjust, bringing it back to optimal function and to its natural, healthy and balanced state.
Scientific, Safe and Non-invasive
One approach to health and wellness is to incorporate valuable nutrients into our daily diet. Therapeutic Ketones can be a particularly useful key. This short animated video explains!

My Headaches are Gone

When I first came to BrainJoy I had headaches that made me feel almost suicidal. I had huge stress and tight muscles all the time. I slept terribly and often woke up feeling like I had been run over by a bulldozer. Now I sleep well, wake up before my alarm clock feeling well rested and energized. I have a positive attitude and feel clearer and more focused. I realized that I had my shoulders up around my ears because, as a full-time mom, I was always doing everything for everyone else and was way too busy. Now, my headaches are gone and I don’t take on what doesn’t belong to me. Thank you Kathleen for BrainJoy and for being online for me to find you. You’ve changed my life. I don’t know what I would have done without you.

Pain Relief

The 13 sessions I had at BrainJoy helped me so much. The constant pain and muscle tightness I suffered with for the past two years is totally manageable without all the medications. I feel so good we are repainting our house. I have enough stamina to drive long distances and feel good enough to visit old friends. I can’t thank you enough.

BrainJoy Helps Depression

I believe that due to family dynamics I was mildly depressed most of my life. Waking/sleeping transitions were always the hardest times of day for me. Iʼve read a lot of self-help books, had various forms of counseling, meditated, and done thousands of affirmations. Who knows what I would be like if I had not done those things, but I was still feeling like I was missing something – some degree of success or happiness that I ought to have been able to achieve. In September 2011, I did brain training with BrainJoy in Medford, OR. I didnʼt notice much of a change at first, though my friends claimed to.
