Treating Root Causes with Functional Medicine
Functional medicine is a distinctive approach to treating health problems beyond the usual methods. We don’t just treat symptoms with medicine; we look deeper to see how your body’s systems, habits, and environment all affect each other. Whether you have ongoing fatigue, digestive problems, hormonal imbalances, or an autoimmune condition, our goal is to get to the bottom of your health problems.
Functional medicine specialists have extensive training in identifying the underlying causes of long-term health problems. Their approach is comprehensive, considering your mental and emotional well-being and spiritual health. By providing “patient-centered” care, they try to understand you and your unique health situation by collecting information about your habits, past medical conditions, family medical history, and current needs.
Why Our Patients Love Us
EXCELLENT Based on 99 reviews Posted on Google Kris PintoTrustindex verifies that the original source of the review is Google. I’ve been working with Martin and Tree of Light Health for over a year, and the difference in how I feel has been remarkable. We’ve worked on hormone balance, peptides, energy, sleep, and my overall health and wellness. I can genuinely see and feel the results in my energy, sleep, skin, hair, and nails. Martin takes the time to look at the whole picture and has been incredibly supportive throughout the process. I’m very grateful for everything he and the Tree of Light team have done for me and my family. Highly recommend.Posted on Google Beth WestbrookTrustindex verifies that the original source of the review is Google. I am grateful to have found Martin three years ago and that we have someone in Atlanta so knowledgeable in all of the latest approaches to holistic health and wellness, and who applies ART (autonomic response testing). One family member has resolved all GI issues and is off all prescription meds, and seeing improvements across the board; a second has also seen significant improvements in overall health and wellness. Martin and his team are curious, dig into each individual’s root causes, provide understandable explanations and have a kind, caring and professional bedside manner.Posted on Google MichelleTrustindex verifies that the original source of the review is Google. Be very careful before engaging with this business. Tree of Light Health feels more like a financial screening operation than a true place of healing. They actively look at your personal financials before making a decision to approve you as a patient, which is highly predatory. They are preying on people who are looking for real wellness solutions. Avoid them and look for an ethical provider who actually puts patient care ahead of financial vetting. UPDATE: The owner’s response is a corporate deflection. While they claim they don't pull "official credit reports," they absolutely use their own intake documentation to vet a prospective patient's financial capabilities before granting care approval. Real medical ethics mean assessing a sick patient's health needs first—not gatekeeping access to a doctor based on a financial screening mask as 'transparency.' My warning stands: look for an ethical provider who prioritizes human care over financial clearance.Posted on Google Shadia VincentTrustindex verifies that the original source of the review is Google. I started seeing Martin a year ago with IBS issues that the doctor told me that nothing was wrong with me, he listened to the what symptoms I had run different tests he listened to my concerns came up with a plan to resolve the root cause I never felt rushed his knowledge was amazing and he explained everything to me now a year later and I feel so much better. I’m so glad that I came to him. I highly recommend him.Posted on Google Sophie EkstromTrustindex verifies that the original source of the review is Google. When I first found Tree of Light Health, I was really struggling — brain fog, anxiety, so many gut health issues, fatigue, significant back pain. I had had prolonged mold exposure, and my health was a mess. Martin took one look at me and saw that my nervous system was dysregulated. Before I even had had my first appointment, he recommended a nervous system program to me that was life-changing and jump started my healing journey. After my first appointment where Martin discovered all my gut issues (SIBO, candida, etc) and my heavy metal toxicity, in addition to the severity of my mold issues, he gave me all the supplements and protocols I needed to start healing. I followed Martin’s protocols as closely as humanly possible, and within four months, I felt like a new person, truly. It feels miraculous. My gut symptoms have mostly disappeared; my ever-present brain fog is gone; my mold symptoms are all gone; my chronic issues and back pain are healed. Martin and Charis are truly such a gift to me and to the greater Atlanta area. So many excellent doctors and nurses have looked at my bloodwork and my labs when I was at my sickest, and they told me I was perfectly fine and healthy. Martin is the only nurse practitioner who found the underlying issues and put me on the road to recovery. Thank you, Martin and Charis, for all you have done for me and for my family. It really does feel like I have my life back!Posted on Google JillTrustindex verifies that the original source of the review is Google. Very, very thankful for Tree of Light Health. While I’m a newer patient, they give you so much time and care. I’ve never had this level of detail and communication from a functional doctor before. As I put protocols in motion, I’m excited to see progress. Protocols are given with caution and explanations leaving no uncertainty. They genuinely seem happy to hear from me versus burdened by questions. I’ve always been hesitant to reach out to doctors/nurses for this reason, but I’m having to retrain myself to be communicative with both positives and negatives. They want to know! If you’ve struggled to feel heard and are dealing with complex medical issues, I’d definitely reach out Tree of Light Health!Posted on Google Courtney GoodwinTrustindex verifies that the original source of the review is Google. I cannot recommend Tree of Light Health highly enough. After struggling with ongoing digestive issues, bloating, fatigue, brain fog, mast cell symptoms, and mold-related health concerns, I finally felt like someone was looking at the whole picture instead of just treating symptoms. Martin takes an incredibly thorough and personalized approach. He spends the time to listen, explain things clearly, and develop a plan that addresses the root causes of health issues. Since beginning treatment, I have seen significant improvements in my digestion, energy levels, sleep quality, weight loss, overall resilience, and quality of life. My recent testing has also shown meaningful progress, including resolution of my SIBO and improvements in other key health markers. What I appreciate most is that I never feel rushed, dismissed, or treated like a number. Martin genuinely cares about his patients and celebrates every step forward, no matter how small. His knowledge of mold illness, gut health, mast cell activation, functional medicine, and complex chronic conditions is truly impressive. While I still have healing to do, I am incredibly grateful for the progress I've already made and feel hopeful about my future health for the first time in a long time. If you are looking for a practitioner who is compassionate, knowledgeable, thorough, and committed to finding the root cause of your health concerns, I highly recommend Tree of Light Health.Posted on Google Nylah RTrustindex verifies that the original source of the review is Google. A truly healing environment. The light therapy sessions are relaxing, professional, and effective. Highly recommend this practice for anyone looking to support their wellness naturally. Mr. Van Lear does a great job breaking down what’s happening in your body in a way that’s easy to understand.Posted on Google Tracey RomainTrustindex verifies that the original source of the review is Google. Martin is an Amazing provider! I have worked with other holistic providers and he is by far the best! Everything he recommends for his patients he does himself! I feel better already and there is so much more to come! ❤️Posted on Google Joanie ThomasTrustindex verifies that the original source of the review is Google. Tree of Light Health has been instrumental in supporting my health journey. Martin and his team have helped me with hormonal balance, mold/biotoxin support, and a thoughtful, root-cause approach to issues I had struggled with for years. Since starting care, I've seen meaningful changes — hormonal balance, improved energy, and less brain fog. I really appreciate the time, thoroughness, and holistic perspective they bring to every visit." I came in to the practice with a completely different idea of what we should do to treat issues I was experiencing than what we ended up doing. I'm glad Martin decided to treat me exactly as he did because 3 weeks later the issue resolved. I had no knowledge of or trust in the method he treated me with, so the placebo effect was non-existent. His knowledge and experience is vast. Don't hesitate to try the modalities of treatment considered to be more "woo."
