Functional Medicine Health Coaching

Health as Infrastructure

When the brain is clear and the system is regulated, performance follows.

I help high-performing individuals restore energy, improve cognitive clarity, and support long-term brain health through a deeply personalized approach that blends neurocognitive work with functional medicine.

We address the foundational drivers of brain performance—sleep, nutrition, movement, and nervous system regulation—not as checkboxes, but as powerful levers that directly shape how you think, feel, and function.

This is where how you feel, how you think, and how you function all begin to align.

ABOUT KAREN

Where Lasting Change Begins

How do you create healthy habits that truly last?

Sustainable change doesn’t begin with willpower — it begins with regulation.

We start with the foundations: nutrition, sleep, movement, stress resilience, and meaningful connection. But instead of layering on more “shoulds,” we address the nervous system patterns that drive your behaviors in the first place.

Through a personalized, root-cause approach, you’ll learn how to reset your nervous system, build awareness through somatic practices, and shift the underlying stress responses that sabotage consistency. From this regulated, grounded state, healthier habits become natural — not forced.

Small, intentional shifts in mindset, physiology, and daily rhythms compound into meaningful transformation — guiding you toward lasting vitality, clarity, and optimal wellbeing.

“An excellent asset to the team we had at Cleveland Clinic Center for Functional Medicine. On a personal note Karen is a true, compassionate, empathetic, go-getter with a personality that is contagiously motivating.

She comes highly recommended from myself and other practitioners -I even heard Dr. Hyman describe her as inspiring.”

“I have made some significant changes moving toward a healthier lifestyle. I’ve lost 25 lbs and have an exercise routine that I actually look forward to. I’ve realized that the accountability and support I received as well as critical thinking about my behaviors were the keys to long term change. Karen has helped me and continues to help me achieve these goals in a very supportive non-judgmental way. I am so glad I made the commitment to continue my work with her.”

– Michelle C.

"I just wanted to say Thank You! I just returned from an 8 day vacation to Hawaii with my oldest son. He wanted to surf and hike the volcano. I was able to do it all and actually outlast him energy wise. The flight back was a bit draining and I seem to have caught a cold, but I am so proud of my body to expend as much energy as I asked of it and not get too fatigued. I would not have been able to do this prior to working with you. Thank you for helping me tweak things with my health. It has made such a difference already."

– Tamar C.
