“You made an extra effort to get to the root cause of my problem. It’s the best experience I’ve ever had with any care provider.”

Steve, patient of MaxWell Clinic

“They actually wanted to help find the problem & take care of it instead of brushing me off or throwing pills at me.”

Sherry, patient of MaxWell Clinic

“I am able to get out of bed every day. I am feeling better than I have in a long time. My energy level is coming back. I have a positive outlook on life again.”

Kim, patient of MaxWell Clinic

We believe you’re more than your diagnosis.

At MaxWell Clinic we have pioneered a revolutionary approach to healthcare, which we call person-centered medicine. Rather than simply suppressing your symptoms, we seek to understand why those symptoms are there. Our unique model of care combines proven functional medicine with aspects of both conventional care and cutting edge research.

Here’s how we do it:


We listen.

Your story is critically important to us – not only because we want to get to know you personally, but because it may hold clues to your health struggles or disease risks. We spend significant time in meaningful communication with our patients, asking questions, and deeply listening.


We test.

Individualized, diagnostic testing can help us identify the root cause of your health problems. We partner with over 30 leading labs from around the world. We use extensive in-office diagnostic testing to evaluate the many potential underlying causes of disease.


We treat.

We do “what is wise and works,” employing the safest tools available to fully harness your body’s innate healing capacity. Your course of treatment may include prescriptions for diet, lifestyle, supplements, medications, IV therapies or procedures such as Neurofeedback and Regenerative Plasma Exchange.


We support.

You’re not alone on this journey because we aren’t an ordinary clinic. At MaxWell Clinic, your personalized wellness plan, specific to your challenges and goals, will be designed by an entire team of caring professionals. Your MaxWell Advocate, Nutritionist, and Clinician will work closely with you to fine-tune your care and move you closer to your goal of maximum wellness.
