Ever heard of a Functional Diagnostic Nutrition Practitioner (FDNP)? I hadn’t either until I became very ill a few years back and became one.

What does FDN really mean?

  • It means helping you discover what works best for your individual body by using a holistic approach in identifying internal and external root cause stressors. Attacking these stressors from all angles, I introduce food as medicine based on functional lab tests preformed AND your symptoms, recommend targeted pharmaceutical grade supplements, suggest specific exercises in your current state of health, and help with other lifestyle management skills. Working closely with you in decided amounts of visits, creates long term success and independence in managing your OWN healing for the future.



I have ALWAYS been an active person. Athlete. Outdoors enthusiast. Adventure seeker. Ironically, I didn’t care to watch what I was eating or drinking, how I was sleeping, or my mental health. I was always taught pain=gain. Just don’t stop. OR pay attention to anything that hurts. Until one day two
years after I had to have a total hysterectomy at 36, I needed emergency gall bladder surgery and found myself unable to function. I went from running 10 miles per day and working full time, to not being able to walk around the block. I was in and out of bed for FIVE years, visiting a long list of specialists to no avail. It was a VERY scary time of panic attacks and anxiety, high blood pressure, low blood pressure, blurry vision, total exhaustion, digestive issues, fainting, blood sugar problems, and not being able to sleep. All of these came in episodes I could not predict. After years of unsuccessful Doctor’s visits and testing, I began my own health journey. Changing everything I could (diet, stress, supplements, relationships, my spiritual walk, NO exercise and LOTS of rest,) I began to get better through research and holistic practitioners. The very best outcome happened. I began to talk and help people who were going through similar problems: dead end help! In 2012, I decided to go back to school to officially become a detective of deeper root causes and keys to unlock frustrated health issues. The bonus is that I have learned and continue to learn so much about how our complicated systems work together and I am now sharing with the world! That is how Living Tree was created. I have found my calling! I now work with high energy people who have crashed and need individualized help back to their amazing selves!

Since I have started this company, I have had some circumstances beyond my control that has pushed the envelope of my health. To you that may not have experienced physical crashes like I mentioned above, but you have faced trials of great magnitudes (Moving, losing loved ones or a job, experiencing divorce, unplanned financial loss, betrayal, taking care of an elderly or sick parent, or even the effects of addiction,) my programs are especially for you! Because I too have experienced many of those stressors all in the last three years, I have realized the importance of taking care of myself and know the ramifications of stress. Please reach out and let’s have a chat!

When I was searching for a functional practitioner to help me treat my ulcerative colitis and acid reflux naturally, it was critical that I find someone who had gone through their own gut health journey who could really support me based not only on expertise, but experience. The lab tests we ran came back showing I had multiple gut infections that were behind my UC flares, and as soon as we addressed them through a protocol, my UC went into remission and has been there ever since! I’m so blessed to have found Treva, she truly set me on a path to healing and because I was so inspired by her work, I made the leap to become an FDN practitioner myself! Thank you Treva, for everything

Kristin Thomas

I came to Treva suffering from GI problems ranging from gluten and lactose intolerance, to IBS,
and I was a stressed-out pre-med student who abused caffeine and rarely slept. Years of this
lifestyle cascaded into unstable anxiety accompanied by many panic attacks each week. Treva
took the time to listen to my symptoms and validated my concerns in a way that no other
practitioner has before, explaining that mental health and gut health go hand in hand. I was
thrilled to have functional lab testing and natural supplementation that offered help opposed
to long term antidepressants or SSRIs. This last year as I continued with her support—I have
been blown away by the results. I am a completely different person. These natural
interventions have reduced my anxiety to almost none and given me a new confidence I have
never experienced before. Treva has helped me accomplish seemingly impossible things – like
cutting out caffeine as a first-year medical student. I am truly happier and healthier than I have
ever been. Treva works to give her clients restorative solutions that fit with their individual
goals and priorities – this is a unique component of her approach and making these incredible
life changes are not possible without the detailed support she gives.


I’ve tried for years to maximize energy, manage my weight and control my blood sugar and was overwhelmed.  Nothing worked. And then I met Treva. Through a series of simple tests, tracking data and deep dive conversations, Treva set a path right for me. We tested, tried and readjusted as she gathered more information and watched my results.  She created a plan to manage diet, exercise and reasonable expectations based specifically on my needs and my goals. A lifestyle shift that I actually enjoyed. I lost weight with Treva’s help and now understand how to sustain health. I just generally feel better, perform better and look better.  And to top it all off, Treva brings joy and care to the process too.
