In short, I highly recommend Dr. Ettinger. He is an amazing functional medicine practitioner. I had been suffering with migraines and extreme fatigue for about 10 years, getting progressively worse. By 2017 I was experiencing up to 14 migraine days per month. I tried Kaiser's Migraine program but it didn't work for me. I requested food sensitivity tests and they didn't offer any comprehensive testing. Their recommendation was multiple prescriptions. I tried my own troubleshooting with food but couldn't figure it out. I tried a holistic Ayurvedic practitioner and a different nutritionist, who wanted me to buy expensive supplements through him. As a last-ditch effort to try to avoid taking prescription medication, I went to see Dr. Ettinger. He reviewed my previous blood tests as well as new ones and got me on the right track with foods to eliminate and supplements to take. Following his recommendations, I started seeing results pretty quickly. My extreme fatigue is gone. I experience migraines only 1-3x per month, and often it's when I've eaten something I knew I shouldn't have. I am so grateful for the knowledge that Dr. Ettinger equipped me with. He's a ray of light within our broken health care system. Before seeing Dr. Ettinger I kept thinking, there has to be a natural solution. He's the only one that found that for me. I have recommended him to many friends and would recommend him to anyone who feels let down by traditional healthcare, or if you feel like you've tried it all and nothing works...go see Dr. Ettinger. read more

This review is about four years overdue, but I cannot express enough gratitude for Dr Ettinger. I originally had been seen in 2020 for SIBO, and the treatment was life changing. Whether you are coming to him with unanswered health concerns or a chiropractic adjustment, you will be more than happy that you did! He is a wonderful human who takes his time with every single person to ensure quality care, and to spread knowledge to give patients the tools to help themselves live happier & healthier lives. You will always leave his office feeling better in more ways than one. He is a true healer. Thank you Dr. Ettinger for everything over all the years ! I can never thank you enough read more

Incredible doctor literally for anything SIBO or longevity related. He is the REAL deal. No frills, insanely intelligent and inquisitive. He has changed my life. read more

Dr Ettinger is probably the 6th chiropractor I have seen in the OC and hopefully the last. He is extremely knowledgeable and caring. He takes the time to understand your individual needs and concerns. His adjustments are not aggressive but also not to slight either. He offers exercises and supplements that the body needs instead of just saying chiropractic care is a cure all and you need to return all the time. I appreciate his suggestions and find him very trustworthy. read more

Best of the best Chiropractors period most knowledgeable person I know!!! 32 years of experience he is amazing!!!

This is a LONG overdue review for Dr. Marcus Ettinger. In summary, Dr. Ettinger is an incredible functional medicine practitioner and overall human being. He was my first ray of hope during an extremely difficult time with my health and I will ALWAYS be grateful for his expertise and kindness. About a year ago, my health started to deteriorate. It was a horrible and complicated downward spiral of gut health issues that started with stomach acid refluxing up to my throat, followed by the inability to eat without throwing up or having severe upper abdominal pain (pain so bad that it often felt like I couldn't breathe). I had dropped from 102 lbs to 87 lbs over the course of 2-3 weeks The issues were so severe that I had developed a deep fear of eating, and I was constantly extremely exhausted from both the anxiety I'd developed on top of the lack of proper nutrition. Desperate for help, I started researching how other people had solved their gut issues and somehow I'd found Dr. Ettinger online. I called for a consultation and Dr. Ettinger was the FIRST person who actually LISTENED to me and gave me HOPE that I could go back to eating and living normally. I'm pretty sure I was crying over the phone, and he was still very patient with ensuring I felt heard. During my first visit to Dr. Ettinger, he provided me with the supplements needed to help my body heal. At that point I'd never turned to supplements for my health and he had given me quite a lot. I admitted to him that I was afraid (keep in mind the anxiety) but he was very kind to talk me through things. The changes in my ability to eat were pretty much immediate. In the next few days I was able to eat without throwing up or developing abdominal pain, which was incredible. While I was required to slowly re-introduce food and limit what I ate at first, finishing the supplement protocol itself took 3-4 weeks. My situation was extremely complicated, and while I did end up seeing other health practitioners (a therapist, nutrition coach, PT, and acupuncturist), Dr. Ettinger gave me the crucial steps for my body to begin to heal. If you are experiencing gut health issues like I was, PLEASE reach out to Dr. Ettinger (don't worsen your health by trying to Google / self-diagnose like I had done). He's a wonderful person and I've recommended multiple colleagues to him already. Thank you Dr. Ettinger!!! read more

This review is way overdue - my apologies, Dr. Ettinger!! Writing this review while eating my lunch, I often think about the discipline that Dr. Marcus Ettinger instilled in me in the two meetings that we had a few months back and I'm ever grateful that I was ever introduced to him! I eat lunch daily whereas before I would eat maybe twice a day, or one whole meal that would go on for hours because I was just too damn hungry! I cannot tell you all how undisciplined I was with my eating, so much so that my body rebelled with headaches -borderline migraines- every single day. I would wake up with them and go to sleep with the same. This became my primary reason for my visit with Dr. Ettinger. I also had gallbladder surgery a while back which was another reason for my visit with him, and honestly guys, he kinda saved my life! Of course I was hesitant to go in because I already knew my habits were quite bad, embarrassing even, but he didn't make me feel ashamed of how I treated my body and explained very clearly why my body acted the way it did. I was asked to do some lab work before going in to see him for the first time, and he calmly explained how bad my bloodwork was - not to scare me BUT to inform me that ALL this can be changed with just a drastic change of lifestyle and diet, which I gladly and humbly obliged. He first ensured I was ready to take the next step as he doesn't believe in traditional medicine and asked if I was willing to undergo a drastic lifestyle change; you MUST be prepared to WANT a change. He provided me with some vitamins, some Super Enzymes to rebuild my gut, and guided me to a better and cleaner diet; this change made me feel 133% better, best I've felt in all my life. If you're tired of doctors stuffing you down with experimental medicine, check out Dr. Ettinger - you won't be disappointed by this investment in your Self. read more

I have been in tears for how much Dr. Ettinger has helped me. Today, for the first time in my entire life I don't have menstrual pain. Not lessened menstrual cramping, none. Zero. 13 years of vomiting, fainting, dizziness, hospital visits, endless exams/tests, codeine, sick days, failing exams, sobbing in agony... my whole "adult" life I have isolated myself in preparation for a quarter of the year of living. Canceling plans, work, school, socializing, family, fun... And today is my first day ever without pain. Ever. THANK YOU!!!! read more

I went to Marcus Ettinger to be treated for H-Pylori. Prior to that, i was being treated by 2 GI's (Gastroenterologists) who had told me that there is nothing more that they can do for me. I had taken 5 courses of antibiotics and that darn bacteria did not go away. I found Marcus through a chat forum for H-Pylori and when i contacted him, he gave me an appointment right away, the following day. What a relief!! I was at a loss after what the GI's had told me. Marcus gave me the treatment and within 3 weeks, the bacteria was gone. My GI asked for the information on Marcus so that he can refer patients to him. Marcus is the picture of health, great service; a few times, he went to the clinic just to see me. He is truly concerned for his patients and treats them as his number one priority. As i am writing this, i have tears in my eyes, when i went to him, i had no hope whatsoever about getting rid of H-Pylori... after what the GI's had told me. His clinic/office is very clean and he is a generous and kind practitioner. He gives you only what you need and he has a vast knowledge about health and keeps up to date. What a joy it is to be treated by Marcus Ettinger DC I was just at his office, you come back feeling happy and elated... Of course, he knows his subject matter and he is up to date with his information. read more

I saw Dr. Ettinger about 5 times over a period of 6 months and he helped me to get rid of a nasty bacteria called H-Pylori. I was fighting my stomach problems for about 4 years, before I found Dr. Ettinger, doing online research. The first contact with Dr. E. was over the phone. He called me right back, after I left him a message. That's how everything started. I live in LA, his office is in Orange. To stay out of heavy traffic, I would leave Saturday morning early to go to my appointments. Dr. Ettinger has always been kind and patient, even when I was late. After all those years I can finally eat and drink whatever I like. I am so happy, I have my life back. I highly recommend Dr. Ettinger, his knowledge is amazing and he really loves what he is doing. He has given me my life back. I will always be thankful for it. Thank you Dr. Ettinger. (I have consulted different health professionals, did research for hours and spend tons of money to cure myself. H-pylori is a nasty bacteria and many people are still not cured after many rounds of antibiotics.) read more

Went to Dr Ettinger for a consult and left the office feeling such relief finally someone understands and can help. He is so smart and explained the bloodwork so thoroughly. The consult took over an hour. He suggested some supplements that will help me feel better. Looking forward to my next appt read more

After two years and 8 different health care providers, Dr. Ettinger healed me in a matter of weeks with his approach. For two long years, I experienced terrible abdominal pain, blood and mucus in my stool, and general exhaustion. I was beginning to give up on being well again and thought feeling this way was my new "normal." I tried everything. My digestive symptoms were what most people on the internet call "rope worms," which Dr. Ettinger believes is a form of colitis. I saw GI specialists, Naturopathic Doctors, Integrative Medicine Doctors, Chiropractors, Acupuncturists and general physicians. I spent thousands of dollars and found no relief. I did the Specific Carbohydrate Diet for 2 years (no sugar or starchy carbs). My last ditch effort was to call Dr. Ettinger. Dr. Ettinger's approach is simple compared to what my previous naturopath had me doing. And most importantly, IT WORKED!!! I noticed results within a week. I have tons of energy, normal stools, no abdominal pain and no mucus or blood. Dr. Ettinger is the real deal. He is compassionate, a great communicator, and has a genuine interest in helping heal his patients. read more

This review is way long overdue for Dr. Ettinger. To make the long story short, Dr. Ettinger is an amazing, brilliant functional medicine practitioner and a nice person. I Like others tried to perform research online and try to play Doctor on themselves. After losing hope on trying to cure psoriasis on my own, I finally setup an appointment to see him. He listened, provided me courage, and explained what not to eat, what to eat and what supplements (don't like taken harnful drugs that my dermatologist recommended that didn't work) to take and three months later, my psoriasis cleared up 100%. Don't waste time, go see Dr. Ettinger and be on your way to recovery. He is my go to Doc for any issues. He finds the root issue and does not bandage it with horrible, harmful drugs like your standard doctor. read more

I first went to see Dr Ettinger April of this year. I was having a terrible Ulcerative Colitis flare which ended up putting me in the hospital for a week. With Dr. Ettinger's wisdom and experience he was able to help guide me so that I could get off of my medications and heal in a more holistic way. I was truly at one of my lowest points. He was gentle, patient, compassionate and very understanding. He gave me hope so that I could believe that I would heal. With some trial and error we found what works and I am almost in complete remission and have gained back the 20 pounds I had lost during my flare. Dr. Ettinger is the real deal ! A true holistic healer with the science to back up his approach. He is very well read and researched. I trust his wisdom and I am so thankful to have him as part of my healing team! read more

Dr Ettinger is extremely patient and knowledgeable. My husband and I have both gone to him. We have been under his care for the last year and have followed his advice and regimen allowing us to both live a healthy lifestyle and help with our health issues. My husband had a chronic cough that he inherited in the military when he cought pneumonia for the last 15 years and was getting progressively worse. We had gone through so much trying to find a remedy he was hospitalized many times and seen by many specialist, he was diagnosed multiple times and with diffrent things becuase know one was certain what he had. WE WERE EXHAUSTED and felt hopless we had hit a block wall. We came to Dr. Ettinger with a spark of hope and prayed he could do something. He not only helped my husbands cough he became our family Dr. Thank you Dr. Ettinger for your kindness, advice and patience. You have tought us so much. We will be forever greatful. read more

Updated review as of 11/17/15: Since my first review both my husband and I come to Dr. Ettinger for Chiropractic care on a regular now. We like his holistic approach and how he gives every client his attention and how he educates you with lots of useful info. My review 9 mos ago: It must be my intuition that lead me to pick Advanced Healing Center among all the other ones here on Yelp. What stood out to me was the word "healing". I had another sciatica attack today and was in desperate search for a Chiropractor and of course I had to go through the long list on Yelp. What I liked about Dr. Ettinger is his holistic approach to his treatment, he also takes time to explain what he's doing and why, not only did he do Chiropratic adjustment but he also tested me for deficiency in minerals. I learned so much more about the root cause of the sciatica attack. I was very satisfied with my visit and I definitely feel a huge difference with just one visit, I noticed I have more energy and my back feels 90% better. read more

I began seeing Dr. Ettinger 2 years ago. A good friend of mine referred him to me as she has been attending his practice over 18 years now. Originally I came to see him because of hip issues and my husband had serious back pain. Dr. Ettinger has helped us recover and is so wonderful at sharing extra tips and showing us how to stretch and prevent further issues. He's highly knowledgeable in diet and health. He's gives great advice on eating right and it's definitely helped to maintain weight. He seems to always have a solution for any new body changes. My husband and I see him monthly and are extremely pleased with him. We recommend him to anyone who needs an adjustment, help with weight loss, or wants to truly get healthy. read more

I first met Dr Ettinger a year ago when the practitioner I usually see was not avail. This was meant to be because I have since become the recipient of an excellent standard of holistic care. The sharp stomach pains I had been experiencing for a week were 90% better by that evening and I was able to go to a concert. Also, on later visits, he helped me to identity and treat the bacteria that was causing my sinus infections. I appreciate how present and sincere he is and how I did not feel rushed, as I often do with other holistic chiropractors. Also he is happy to explain the mechanisms behind what he is doing and is never condescending, always willing to teach and share as he goes. Dr E's background in biochemistry and his decades of experience with being a medical detective combine with his patience and empathy to make him a first rate true holistic care provider. read more

Dr. Ettinger is the best! My wife and I have been coming to him for a couple years now. He's very knowledgable and cares about your wellbeing. I get all my supplements from him and he keeps me in alignment! Keep up the good work!!! read more

I had struggled with compounded digestive & psychological issues (IBD) for the better part of 8 years. I'd seen a wide array of doctors, spent way too much money on countless supplements, and tirelessly researched my condition to no avail. I genuinely thought I was going to spend the rest of my life (I'm only 24) chasing my health, never getting better, constantly wishing for a solution. When I came across Dr. Ettinger's articles, I was impressed by the level of clarity, depth of research, and comprehensiveness of solutions. On a whim, I gave him a call. It was the best decision I've ever made. After getting my test results back and following Dr. Ettinger's (much simpler and much cheaper than what I had previously been doing) protocol, I was a different person. For the first time in my life, I consistently wake up every day feeling well. I'm so thankful I made the change, and so thankful people like Dr. Ettinger exist. If you have a chronic health issue, please don't ever give up. Your health is within reach, and people like Dr. Ettinger can help you find it. read more

Sooooooooo let's add another 5 star review for Dr. Ettinger. My family has been seeing Dr.E for about the last 20 years or so, including my mother, my brother, my wife...........and the list goes on. His skills are insane, his attention to your body is spot on, and his knowledge level just keeps going. Keep it up Doc, see you next time. Todd read more

Dr. E is amazing!! He's professional, personable, and very knowledgeable! He reviewed my lab blood results with me and pointed out that things weren't all "fine and dandy" like my primary physician said. He explained why i was feeling the way i was and started me on supplements that changed my life! He explained to me what i needed and why and i followed his instructions and I'm feeling great. His adjustments are heavenly too and I'm so glad my friend recommended him. His office is nice, clean, and in a good area. Parking is available and free and he seems to have all supplements he recommends on hand so you can start taking them right away. His website is full of useful information and you can also find him on Facebook! If you want to feel better and be healthier, you must go see Dr. E!! read more

I have been a patient of Dr. Ettinger's for over a year now and he has been instrumental in helping me regain my health. When Kaiser dropped the ball, he picked it up and ran with it. He analyzed all of my past labs and discovered issues that were contributing to my chronic pain and inflammation. He created a supplement plan that has really helped me feel well again. He cured my SIBO after prior treatments had failed. He also is an amazing chiropractor. My pain level was an 8 and it's down to a 1-2. My 85 year old mother sees Dr. Ettinger as well and just loves him! His protocols have improved her daily health tremendously. read more

Dr. Marcus Ettinger is the best chiropractor around Orange, and offers exceptional care in a holistic approach. He has helped me with my intestinal issues and given me a treatment plan that no other doctor has offered me. I highly recommend Dr. Ettinger to anyone looking for an alternative way to treat their conditions. He is extremely knowledgable on diet and exercise, and Dr. Ettinger is always doing research and expanding his knowledge on anything you could think of. read more

I can't thank Dr Ettinger enough for making me feel better. His expertise and knowledge are far superior than the many Dr's I've been too. His adjustments are amazing and his tuning into my body chemistry helps me understand what is going on internally. His prices are more than fair for the quality care he provides. I actually look forward to my appointment and the education he provides me about my body. Thank you Dr Ettinger! read more

I was introduced to Dr. Ettinger in 2010 by my girlfriend, and I have been a committed patient ever since. I originally started seeing Dr Ettinger for skin tags. I struggled with skin tags for almost a year before seeing him. I kept getting them removed and they would just grow right back. Dr. Ettinger put me on an anti-virus supplement and they immediately stopped coming back. I have not had one since they left me three years ago. Dr. Ettinger is a one of a kind doc; he treats all of his patients like family and does not recommend anything that you don't test for. I have been seeing him for chiropractic and holistic care for the past three years. I am truly in the best shape of my life and I have more energy than ever before! I have altered my diet tremendously since seeing him; I've lost fat and gained strength since I started following his nutritional advice and my skin has never been more clear. I would recommend Dr. E to anyone thats experiencing physical pain or in need of a better and healthier lifestyle. He knows more about nutrition and the way the human body functions than any doctor I have ever met. He is also one of the most positive and honest individuals I know; you will always leave his office feeling positive and full of energy. He truly is a medical detective! Thanks for everything Dr. E! read more

I started seeing Dr. E in 2010 for high blood sugar. Within 3 months, my glucose level was down, along with my weight. My energy level was up. Since then, he has helped me with high cortisol, which contributes to pain, hot flashes, high glucose levels and many other problems. He recommended a supplement as a blood thinner, and another for ligament health, which helped with hair loss as well. Dr. E is a great listener. He has a vast knowledge of body chemistry. He has done extensive research in the field of natural remedies in place of drugs. I always felt great after a visit with him. read more

Thank you Dr Marcus for helping my family heal and guiding us down a healthy path. I've been to many types of Drs and I'm really impressed with your knowledge and the way you educate us!! read more

Dr. Ettinger has been treating my daughter for over 3 months now for inflammatory bowel disease. Since May, 2011 she has been through many hospitalizations, multiple surgeries and pharmacological treatment - none of which have helped her. Dr. Ettinger has a brilliant mind and is very knowledgeable in the areas of chiropractic, chronic diseases, nutrition, diet and holistic remedies. As soon as we met him, we knew we were in good hands. He has a BIG HEART! He is genuine, sincere and caring towards my daughter and me. We just wish we had found him sooner. I am very grateful to him for his help. On a side note, he is helping me with my chronic insomnia that has plagued me for 18 years. We look forward to our appointments with him and leave feeling positive and happy every time. I cannot thank him enough for everything he has done and continues to do in our journey for wellness. read more

Dr. Ettinger has given me my health back! After so much trial and error with many naturopaths and self diagnosing, I found relief with Dr.Ettinger. He has an amazing ability to understand what is happening to the body and how to correct it. I highly recommend him to anyone who is serious about having absolute health, vitality, and a true personal regimen. read more

My experience was in sharp contrast to these other reviews. Dr. Ettinger (actually he is Mr. Ettinger on the paperwork you have to sign) must have been having a bad day. The client before us stayed to chat and so my appointment started 15 minutes late. Then he was interrupted FOUR times for phone consultations and each time he was distracted when he returned. He rushed so he could be on time for the next customer. Will not go back. read more

I had a heliobacter pylori infection. It produced wind in the stomach and bowel and great pressure, which produced severe pain referred to the chest and so was initially thought to be heart problems. Eventually, it was treated successfully with a couple of antibiotics. They killed all the bacteria in the gut, of course and, although the H. pylori stopped giving trouble, I began to get every infection of every sort that appeared in my grandson's school. He did not have to get the infection - he just passed it on. Everything, until I began to take probiotic supplements. Then after a few years, the symptoms of H. pylori reappeared. Not wishing to use antibiotics again, I consulted Marcus Ettinger, took what he prescribed and the infection was dealt with and, this time, has not reoccured. read more

I have been seeing Dr. Ettinger for a while ( I actually can't recall how many years but maybe since 2012) He is awesome at adjusting me and my NECK and BACK but has also helped me with other issues that I would had normally called my WESTERN Medicine doctor. I feel you need both sometimes but I have gone to him the last two times and he diagnosed me and got me on my way with some simple products (no antibiotics) but more holistic approach. The other thing I love about him is he doesn't put you on all these products....I have been to others that have put me on so many products and have spend tons of money. He has you take what you need...I love his approach and he is one smart cookie and explains in terms you can understand.. Thank you Dr. E, you are well loved. Thank you for your knowledge and caring nature. read more

I have been seeing Dr. E for a long time. His adjustments are spot on, he can tell exactly where you need to be adjusted without cracking your whole back. One time my jaw swelled up like a chipmunk, so I went to the dentist but the Xrays turned out fine. Dr. E did a short exam and told me that I had an infection in my lymph nodes and gave me a supplement to take and within 3 days I was back to normal. What is significant about this is that the dizziness I had been experiencing also went away, I thought I was just getting old as I would drive very carefully. Regular Dr's would probably have cost me a lot and multiple expensive test with no results but within minutues he literally just figured it out. I also use to get these skin tags that after taking some supplements they started falling off on their own. My parents and I use to call him the Witch Doctor, LOL. read more

I've known and been a patient of Dr Ettinger since 2004. He's a very knowledgable chiropractor and an amazing person. Truly cares about wellbeing of his patients and go far and beyond anyone to make sure you're getting well and staying well, a true healer and a friend. His knowledge of the human body and thirst in learning new information is amazing. I'm glad to call him my healthcare provider and friend. read more

Dr. Ettinger is someone who is committed to helping you stay healthy, not lecturing you about all the stuff you're not doing or should be doing. He takes the time to listen and to explain. It's clear he wants to help you, and has helped my me for years I would recommend him to everyone! read more

I have been a patient of Dr. Marcus Ettinger for a couple of decades. when I had growing boys I took them to see him--always with good results. I have referred many friends and associates and family to him with total confidence. Good health and healthy living practices are Dr. Ettinger's passion and he is the perfect guy to get anyone on a healthy track and to repair situations that are a physical problem. He knows people and he knows bodies. It is a great combination and one that leads to success. I wholeheartedly endorse him and his practice. read more

Dr.Ettinger is more than just a structural chiropractor. He is a functional medicine doctor. Trained is several different techniques outside normal chiropractic. He interprets labs and has an extensive knowledge of western and eastern medicine as well as nutrition. read more

Dr. Ettinger is, hands-down, the best chiropractor on this side of the Mississippi. No matter what my symptoms show when I go to see him, he always addresses the whole body. It's very refreshing to have a doctor who treats the cause, not just puts a band aid on the symptoms. As a certified massage therapist, I am so happy to have found Dr. Ettinger. When it comes to my health, I will search far and wide for the person that pays attention to detail (which he does) and has in-depth knowledge of all things body related (he always impresses me with his ability to explain how the body works and makes me really understand what is going on). So happy that the search is over and that Dr. Ettinger is an integral part of my overall health and wellness. read more

I have been to many chiropractors throughout the years, (from Fullerton to Newport Beach) and Marcus Ettinger is by far my favorite. I have scheduled visits with him for nutrition coaching and chiropractic care--he really knows his stuff! He is very knowledgeable in all areas of his work, and patiently answers any questions too. Most recently, I fell and bruised my tail-bone and Dr. Ettinger quickly fit me into his schedule for an adjustment. I could barely walk into his office, but he was absolutely mindful of the bruised area and still managed a great adjustment. Dr. Ettinger has definitely earned my trust! read more
