Integrative Functional Medicine

At Stewarding Life Wellness, we take an alternative approach to medicine and nutrition. Whether you are an athlete looking for improved recovery & performance or you are fighting autoimmune disease, energy deficits, hormone imbalances and brain fog, please let us help. The body is designed to function well but can be hindered by multiple factors that lead to dysfunction and finally to disease processes. We want to help you find the areas that are keeping your body systems from optimal performance. This has to be accomplished by looking at the body holistically from a functional viewpoint.  Most medications are not necessarily the enemy but they are rarely the answer.  Consider adding us to your healthcare team to help you find the root cause(s) of your symptoms.

Free Consultations

Hello! I am Jake Duncan, PA-C, Owner and Functional Medicine Practitioner here at Stewarding Life Wellness. 
Here is more information about my story and training. 

The most common questions I hear are, "What is Functional Medicine?" and "How Can Functional Medicine Help Me?"

I want to answer those questions for you in person. If you are in the Dallas-Fort Worth area, I would love to treat you to a fresh Juice or Smoothie from Juice Junkies in Uptown Keller while we talk a little deeper about what Functional Medicine is and how it can help you. This free consultation is a great way to ask me any questions you have while I learn more about you!  

Juice with Jake is every Friday morning. I have four 15 minute slots available each week. Please sign up below for your Free In Person Consultation. Once you sign up, I will call you with the available times for that morning. 

I can't wait to meet you! 

**If you don't live in the Dallas, Fort Worth, or Keller, TX area or just can't make it to a meeting, I do offer free phone consultations. Just fill out the form below or email me at
