You deserve better healthcare.

Traditional physicians are heavily influenced by the insurance companies that pay them. These physicians often see 30+ patients a day and manage between 2,000 and 5,000 patients.

We are different. We work for you. Your Essential Health monthly subscription ensures that you are part of a very small group of patients each one of our doctors manages – typically less than 200. This means you get plenty of time throughout the year to meet with your doctor to focus on prevention.

If you get sick, you can connect directly with your doctor anytime 24/7, and skip the wait times you get with traditional practices. Have a question? Send your doctor an email or text message and get a direct response. Fast.

We approach health care in a new way by evaluating the root causes of illness from a functional and integrative perspective. We get to know your personal health profile and help get you to where you want to be with an actionable plan leading to optimal health.

We are with you every step of the way, every day.

What do our clients say?

A. Bramble

"I came to Essential Health after years of hormonal, celiac, thyroid, candida, etc issues. I had seen countless doctors and naturopaths to which some symptoms were fixed, but my overall health was declining. I was at my lowest point and Essential Health has been able to get my body on the right track and even give me a root cause after years of no one understanding. I highly recommend Essential Health practice to absolutely anyone struggling with hormonal issues, food allergies, candida, and so much more. They are so kind and always go the extra mile!"
