What is the Unique Aspect of Functional Medicine?
Rethinking the nature and treatment of health problems is at the heart of functional medicine, which is more than simply a new way of looking at healthcare. Regarding health issues, functional medicine aims to get to the bottom rather than just treating symptoms like traditional medicine does. This method can achieve a more comprehensive picture of your health, which takes into account the intricate relationship between your genes, your environment, and your way of life.
Why Our Patients Love Us
Andy Adams2025-02-19Trustindex verifies that the original source of the review is Google. I’ve been working with Dr Martin since this past August. I made phone call after phone after moving to Atlanta trying to find a functional med doctor to work with. I finally found Dr Martin who said he’d sit down with me for the time necessary to listen to my needs. Hard to find a doctor whose practice allows for that format of care. Dr. Martin’s evaluations are thorough. Helps you head to toe. Dr. Martin is clearly knowledgeable in many different fields of medicine. Dr Martin lays out a plan for you in a structured format at each visit. I am grateful to Dr Martin. I don’t know where I’d be without Dr Martin. Dr Martin truly cares about you. Dr Martin is a great person. I strongly recommend Dr. Martin for your health needs. William Sawyer2025-02-17Trustindex verifies that the original source of the review is Google. I have been working with Martin for almost a year, and he has been instrumental in helping me treat a number of complex health challenges, including brain fog, fatigue, insomnia, and gut-related issues. His comprehensive and naturopathic approach has not only helped me reduce my reliance on medications but also led me to the root causes of my health issues. One of the most significant discoveries was the presence of low-grade cavitation stress in my jawbone, which was contributing to many of my symptoms. Martin guided me to the right oral surgeon to address this issue, and I recently completed the necessary procedure. Prior to that, he also identified mold toxicity in my system and helped me find the right contractors and remediators to ensure my home was properly treated. While I still have a way to go, I am already noticing improvements in my sleep, energy levels, and overall well-being. Another standout aspect of working with Martin is his responsiveness—he provides incredible support between office visits, even after hours, which is something I have never experienced with conventional or naturopathic practitioners. I am truly grateful for Martin’s dedication and expertise, and I look forward to continuing this journey with his guidance. If you’re looking for a practitioner who genuinely cares and takes the time to get to the root of your health concerns, I highly recommend him. Emily Harrell2025-01-03Trustindex verifies that the original source of the review is Google. Martin is a natural healer that truly cares about helping his patients feel better. I have been on a health journey for the past 8 years and have seen multiple practitioners all over the world. Martin has been integral in helping me manage and treat the effects of chronic Lyme, coinfections, mold, CIRS, EBV, parasites, long covid, etc. Instead of focusing on each of symptom and diagnosis, he thinks about the root causes and treats the terrain all while keeping bio individuality in mind. If you are looking for an intelligent, passionate, kind, and understanding provider to help you treat complex chronic conditions, I highly recommend scheduling an appointment with Martin at Tree of Light Health. Hugh Miskel2024-12-30Trustindex verifies that the original source of the review is Google. "I’ve been working with Martin since August 2021 to address several complex chronic health conditions, including heavy metal toxicity, dental cavitations, elevated blood pressure, and homocysteine levels. The care I’ve received has gone beyond managing symptoms—it’s been about uncovering and treating the root causes of my health issues using advanced tools like biofeedback, heart rate variability testing, genetic analysis, and naturopathic principles. Martin has been thorough, compassionate, and incredibly knowledgeable, helping me make significant progress in my health journey. I feel truly supported and confident in the direction of my care." Jay Makhija2024-09-22Trustindex verifies that the original source of the review is Google. Dr van Lear is awesome! Anthony2024-08-25Trustindex verifies that the original source of the review is Google. I never go out of my way to write reviews because over the years nobody has helped me see the light until now. Prior to finding Martin I was running in circles, the classic doctor to doctor story, different money hungry functional medicine clinics, running to mexico for different treatments including lyme and stem cell protocols. I finally got lucky and found Martin. Within months my symptoms started to improve with his guidance and treatments, I was honestly baffled because I had been fighting so hard for so many years suffering and wasting money and energy away getting no where. So to finally see results felt like a miracle. I no longer had to spend hours on end trying to educate and self doctor myself either as I felt I finally found someone with a truly deep knowledge in the field of health. Whatever I thought I knew he was 1000 times more educated. I was able to trust and let go and that in itself was a weight off my back! If you’re lucky enough to have run across this man don’t hesitate to put your trust in him for your healing. He’s got your back, cares and is a genuine human being. If fighting lyme, mold, parasites, toxins, healing the gut or whatever nasty stuff you’re dealing with Martin is ready to go to war. I travel across the world just to come to his clinic in Atlanta, Georgia for my tru dose prp, energy work, and in between consult with him remotely. I’ve gone from 20% to nearly 70-80% healed in his care and i know I’m not far from 100. If you’re here reading this and in search of someone who can heal your chronic health issues… consider yourself VERY lucky! PRISCILLA O2024-08-10Trustindex verifies that the original source of the review is Google. Van Lear is an exceptional holistic practitioner who is very knowledgeable in his treatments. He's broad in understanding the weakness of the body and uses a diverse set of treatments to heal the body on a wholesome scale as he drives to do holistic care from an advanced treatment perspective. He and his staff (Charisse) have been very kind and helpful with any concerns I've had throughout this process. He has given me more understanding that the healing of the body is not something that is done overnight nor can be done in a month but that it needs to heal on its time and with learning and understanding and making foundational healthy habits along with the other options he has provided, my health is progressively improving as I'm continuing with him. He's been a significant benefit to my improvement. Sarah O.2024-08-01Trustindex verifies that the original source of the review is Google. Martin van Leer is a terrific doctor! I highly recommend. A holistic approach is a cheaper and more effective at healing certain ailments than going to a regular doctor. The medical field hasn't quite found the balance between when pharmaceuticals are necessary and when a more natural approach is necessary. In this rat race world, pharmaceuticals are being used as a quick fix to get you back to work, rather than giving your body time to rest and recover. I came to van Leer with: - Extremely bad menstrual cramps (used to take 12-16 ibuprofen for all five days that I bled), - Low energy (struggled to go hiking, skateboarding, driving long distances; even struggled with doing basic chores), - Joint pain after eating certain foods (a combination of hyperthyroidism and leaky gut). What I learned: it takes years to break your body down and there is no instant fix. It takes time building it back up. You have to give your body what it needs to heal (including doing something in a slower, lighter, easier way so that your body can heal) The more you strengthen your body the quicker it heals. The biggest things that your body needs to heal have to do with diet and rest. Diet meaning good food, good water and supplements. And just because your body is deficient in a specific supplement doesn't mean that just taking that supplement is going to help. Sometimes your body needs that supplement in combination with a few others to properly utilize it. And I can't say enough about rest. It's not enough to sleep 8 hours a night. If your circadian rhythm is off, you'll sleep but you won't wake up rested. If you work at a stressful job, the stress will break your body down. Think of it like exercising vs a fight or flight response. The first causes your heart to beat faster and makes the muscle stronger. The second causes your heart to beat faster but makes the muscle weaker, which contributes to arrhythmia and stroke. (And I haven't even gone into the negative side affects of stress on the digestive system, nervous system, cardiovascular system ECT.) After only 7 months of following his guidelines: - Changing the way I eat, - Changing the way I sleep and wake up - Taking the recommended supplements, - Following through with the suggested detox methods My menstrual cramps are a lot more bearable. They have gone down from painful to discomfort. (I'm still working my way to pain free.) My hyperthyroidism is under control. The last 5 months, my flare ups have been almost non-existent. (Still working my way to a healthy thyroid) My leaky gut is under control. I'm losing weight and gaining muscle. (Still working my way to a strong, healthy gut.) My low energy has decreased by a good 40%. I can do longer drives with more ease, do chores without becoming exhausted, and enjoy pleasurable activities like swimming, hiking and skateboarding. (Still working my way to a good energy level.) And a special shout out to Charise, who's always so helpful in answering my questions and assisting me with my supplement refills. 5 out of 5 stars ⭐⭐⭐⭐⭐
