What My Clients Are Saying...
"I feel so grateful to be working with Billie Shellist from Functional Diagnostic Healing! I am a difficult client for a number of reasons including the fact that I have mast cell activation syndrome which means I'm highly sensitive and reactive to foods, supplements and my environment. But Billie has been amazingly gracious and helpful with me these last 8 months.
Billie is smart, intuitive, professional and caring...she understands very complicated health issues that other practitioners do not understand at all and is forthcoming in sharing her own personal experiences (“the good, the bad and the ugly”) which I find uniquely authentic and very comforting.
As far as I’m concerned there is nothing an MD can do that Billie can’t do [much] better with the exception of writing prescriptions...Her ability to decipher lab results is exceptional and she seems easily and accurately able to correlate lab work with my symptoms.
Billie creates action plans and custom protocols for me that are intelligent and comprehensive without being overwhelming.
The best part about working with Billie is that she is totally on my side and as excited for my recovery as I am…after our appointments (via Skype) I always feel positive and hopeful. The email support she provides between appointments keeps me going during some of the more difficult times.
As a person and as a practitioner Billie has greatly impressed me…she rocks! " - Karen Rich, Carlsbad, CA
"Billie has been invaluable in my journey towards healing from Mast Cell Activation Syndrome (MCAS). I’ve been through so many doctors and alternative health practitioners. I tried every diet and every supplement to only find temporary relief. And then my hyper-reactive symptoms would reappear with a vengeance.
When I reached out to Billie I was heavily over-supplemented and undernourished. I was down to eating less than a handful of vegetables and had put on 20 pounds! I was reacting to everything from foods to supplements to my environment, and everything in between,
Her investigative approach has helped me end the cycle of a decade of trial and error and get to the root causes of my symptoms. When you have such debilitating conditions it can feel quite lonely and depressing. But Billie has been there every step of the way offering me guidance and support without any pressure.
Her program proved to me that I can heal from extreme food sensitivities, infections and MCAS making the necessary lifestyle changes and trusting the process. After 4 months of working with her, thankfully I’m now able to eat a larger variety of foods and I feel a lot more comfortable in my skin - I already lost 17 pounds. I’m super grateful for the progress I’ve made so far and looking forward to more successes in the future!

"Working with Billie is one of the best things I have ever done for myself. I originally contacted her because my naturopath suspected SIBO. I never could have managed the SIBO diet on my own since it is quite restrictive. I am single and was rarely cooking any more, so it was going to be quite a challenge for me. I ordered 4 weeks of personalized meal plans in which Billie introduced me to foods that have now become staples for me. She makes it so easy since she provides a grocery shopping list for the week’s menus and the recipes are easy to follow and delicious.
She was also the first person that looked at my complete health history and suggested testing for h. pylori , food sensitivities, and Lyme disease based on some unusual health issues I’ve had over the years. Sure enough the test results all came back positive for food intolerance, h. pylori, and Lyme and co-infections. Once I removed the foods I tested sensitive to and started to rebalance my gut, my digestion almost immediately improved.
Thanks to Billie’s knowledge and support I am well on my way to conquering my health issues. My only regret is that I didn’t start working with Billie years ago. She has tackled so many of her own health issues; she understands what it’s like and what the challenges are. If you decide to work with her, you will not regret it! " - Diane K, Colorado
" I cannot say enough good things about working with Billie. I call her the "Lyme Whisperer" because she has been priceless in helping me navigate the very confusing, overwhelming, and complicated ins and outs of treating chronic lyme and mold illness. She was able to help me identify a few things that were really holding me back from being able to make noticeable progress- namely the state of my gut microbiome and my inability to detox. I had been stalled and feeling frustrated when I first reached out to her and now I'm making progress again and watching symptoms lessen or fade away." - Lauren Davis, California
" In my 17-year search of health and wellness and after seeing several Naturopaths, Billie is by far the most thorough practitioner I have ever worked with. She was able to find the root causes of my Hashimoto's, joint pain, general inflammation & digestive issues and thanks to her I'm living a much fuller life with many less symptoms and my Hashimoto's is in remission! Her attention to detail, in-depth explanation of test results and how that correlates to my symptoms, & meal planning make her protocols very easy to follow and effective. I would highly recommend her to anyone who is serious about getting better! " - Tracy Quattropani, Connecticut
"As I have suffered from Lyme & Mold illness, Billie has helped me navigate and prioritze my treatment plan and was the only provider to figure out I was dealing with a severe immune dysfunction called Mast Cell Activation that was keeping me from being able to tolerate treatment and make progress. Once I followed her suggestions on how to calm my hyper-sensitive immune system, my extreme , reactive-like symptoms decreased and I was able to start treating the root causes again. She shared so much of her knowledge and insight not only on MCAS but also on nutrition, supplements, & hormones that has helped me enourmously. She's so caring and has such a passion for wanting to help others achieve a healthier life! " - Valerie, Colorado
"Billie came highly recommended to me from a good friend. When I reached out to Billie I was feeling physically and mentally terrible. I was overweight, anxious, experiencing extreme brain fog, had ZERO energy, wasn’t sleeping, and was falling into depression.
Billie has been just the person I needed and with her help and support I have been able to make much needed changes to my diet and lifestyle that have resulted in drastic improvements in my health. Through lab work and testing Billie was able to determine the root causes of my symptoms, clearly explain and interpret the results of my testing, and gave me a dietary and lifestyle plan to resolve my symptoms. This concrete, fact based approach gave me insight into how my body was functioning and even more motivation to get back in balance.
I didn’t have to wait long to reap the rewards; within one week my sleep began to improve, within three weeks my mood was much improved and the brain fog was clearing, within a few more weeks my energy began to return, and all along I was losing weight. After working with Billie over the last four months the improvement in how I feel is night and day - my anxiety and depression are thing of the past. Her support and knowledge has made a challenging lifestyle reset as easy as it could ever be. I highly recommend Billie to anyone seeking to improve their health through nutrition; I couldn’t be happier with my results and I will always be grateful for her support.” -Rachel, California
"As someone who has struggled with health issues and has researched and tried many different ways to find a way to a better life, I can say I am now looking forward to a great 2017! In addition to extreme fatigue, muscle aches and major IBS issues, life was a struggle many days. Eventually, my homocysteine was over 16 and I had Barrett's esophagus and heartburn. My diet was already fairly healthy, with no gluten or dairy in the past 10 years but I was still struggling daily. After working with Billie, I have now been feeling well for almost all of the last 6 months! My homocystine is down into normal range and my Barrett's is gone!! It's hard enough to find someone who can actually help you live a better life, but the thing that is rare, is someone who will listen and not judge as well. I could not have a higher regard and recommendation for Billie for those struggling with chronic health issues." - Connie Simonds, Colorado
" After 5 years dealing with continual bloating, burping, and gas that affected my life both professionally and personally. The GI doctors I had consulted with told me I had IBS and gave me a PPI to help with symptoms. I told them I wanted to know WHY I had IBS and WHAT I could do to get rid of it but they could not help, just told me that I was stuck with it for life. After meeting with Billie, she suggested we test for SIBO and parasites in order to get to the root cause of my symptoms and lo and behold, I tested positive for parasites, h.pylori, and SIBO. Now after just 90 days of following the personalized gut health protocol Billie provided, I have eliminated almost all of my sympotms and I'm eating foods that I was not able to tolerate before. The other very surprising thing that has happened is that my brain function has also seemed to improve. I find that I can now focus easier, I'm more productive overall, and that I'm in a better mood consistently. I can't thank Billie enough for her support and expertise! " - Ethan R., Colorado
" I'm absolutely thrilled with the nutritional counseling I am receiving. I've never in my 67 years had someone working with me who is as caring and knowledgeable as Billie. I've had Lyme disease my whole life and it feels so good to work with someone who understands my needs and my disease the way Billie does." - Marcia, Colorado
"Working one one with Billie has really been an eye-opening experience for me! I have Hashimotto's thyroid disease and know how important it is to be gluten & dairy free but it was often difficult to stick to. Billie's customized an eating plan for me and gave me a weekly plan with make-ahead instructions to simplify my life. The recipes actually taste good and my family enjoyed most of the meals as well! The food kept me satisfied so that I was able to stick to it and I feel great! Billie also helped me identify my specific food sensitivities and some hidden gut infections like candida and SIBO and after implementing her protocol, I'm happy to report I'm migraine free, my digestion has improved, my energy has increased, and my husband says I'm smiling again! Plus my endocrinologist was very impressed when he saw my thyroid antibody numbers go down by over 50%. " -Melissa Jacobson, Illinois
" The smartest thing I could have possibly ever done for myself was working one on one with Billie. I had been feeling constantly tired, overweight, and generally less than happy and I knew that feeling better was going to have to start with what I was putting in my mouth. Billie took amazing care of all my questions, challenges with feeding my family of 5, and explained in great detail the importance of clean eating. In six weeks of our coaching sessions, I have completely turned around my diet from too much sugar and processed foods to clean, green & healthy! My cravings are under control and I feel so much better overall following an anti-inflammatory diet. Her recipes are delicious and I've lost 20 pounds so far total and have the energy of a 25 year old! " - Minica McCrackin, Colorado
" Working one on one with Billie for the last 6 months has been a life changer for me! I feel so lucky to have met her – truly! As someone who deals with Chronic Lyme Disease, Billie really understood my needs and frustrations. She has taught me so much about nutrition, clean cooking, and taking care of myself that will last me a lifetime. Billie’s step by step protocols, compassionate and fun approach, and delicious recipes have helped me effortlessly lose weight and keep it off without trying and my C-reactive protein went down into normal range after being elevated for the last few years. Billie helped me heal my gut and get my lifetime, chronic candida infection under control. I'm making more progress with my lyme treatments now that we've really worked on healing my gut and balancing and my hormones. I'm so grateful for her support, expertise, and caring ways." - Rachel White, Colorado
" Billie's detox diet was everything I had hoped for and more. My original goals were to get rid of the bloated feeling and "the extra layer" I had been carrying around my mid-section, get rid of my late night snacking habits, learn portion control and get reacquainted with my kitchen. This program helped me meet all those goals and more - I lost 8 pounds and have kept them off, my late night eating habits and cravings have vanished and I feel amazing! I loved the variety and taste of the recipes and surprisingly, so did my family - in fact we are still making the recipes on a regular basis. And the best part about the program is the set menu and shopping list - it made the diet easy to stick to and I never felt hungry or deprived." - Sally Brown, Oregon
" When I first contacted Billie, I had just received the results of my food sensitivity test and was feeling really overwhelmed. I struggled to cook and eat with all my new restrictions. I chose the 4 week personalized meal planning program. This program exceeded my expectations - in fact almost a year later, I still use the recipes regularly. Plus, Billie really helped me create some new and healthy habits and I'm not usually one to stick with things too long! ;) I went from “I hate to cook, I’m a terrible cook” and "How the hell do I eat with so many food allergies?!" to “I can easily cook healthy meals and I feel great!”. Billie and her meal plans get all the credit for that! " - Vanessa, Colorado
" I love the Anti-Inflammatory eBooks from Functional Diagnostic Healing! They have made providing delicious, healthy, gluten free meals for my family every day a breeze. I am not a natural-born planner, nor am I very organized, but with these eBooks, I can spend an hour a week looking at the menus, deciding what to cook each night based on our schedule, and organizing my shopping list. It's genius. My kids are even enjoying the meals and trying new foods which is a huge win! " -Adriana, Colorado
