If you are suffering from pain that may be related to some kind of musculoskeletal issue, do yourself a favor and go see Dr. Yun. I don't know what happened with the people who gave him a negative review, but he will tell you honestly whether he can help you or not. He's extremely knowledgeable, professional and experienced, and he'll take the time and care to listen to your concerns as well as communicate with you thoroughly, so that you can understand firsthand what is happening in your own body. My problem with many medical care professionals is that they sort of try to fit you into some kind of template category and apply whatever medical knowledge they have according to that definition they've put on you. But Dr. Yun really does his utmost to get to know you and work together with you to solve whatever problems are possible to solve. And I've gone to a couple other chiropractors in my life -- one of them was completely careless and didn't even pay attention to me at all, and the other one was also attentive and helped me. But he did not give the same detailed precision and expert attention to me as Dr. Yun does. Also, Dr. Yun does EVERYTHING himself - putting the electric stim node things on you, putting heat packs or ice packs on you, and of course the adjustments and all that...Never seen that elsewhere. I'm SO IMPRESSED with the way he practices...ha, can you tell? :P If you want the details, here's my story.... My mother has been suffering from rheumatoid arthritis for almost 20 years, and in the last year, it got so bad that she started walking with a cane and couldn't cook for herself because she couldn't remain standing for more than a couple minutes. But because she couldn't walk, she stopped leaving the house except when it was absolutely necessary, and often she would roll around on a wheeled desk chair around the house because it'd be too hard for her to walk. Long story short, she wasn't feeding herself, and because she was unable to move, her muscles were atrophying, which made it even harder for her to move....just a horrible cycle, oy. She's tried all kinds of things -- western medicine, yoga, meditation, nutrition, all kinds of natural healing remedies all over the spectrum of crazy fads to ancient traditions from Korea (we're Korean), acupuncture...you name it, she's tried it. Everything short of surgery. And chiropractics. But I started seeing a chiropractor when I was living in Phoenix, so my mom asked around for a good chiropractor referral in Orange County. That's how she found this place and Dr. Yun - our miracle worker! What's amazing is, he first told her that he cannot help her at her first consultation, and told her to go see a rheumatologist. When she told him that she'd been but all they do is give her steriods that don't even really help her manage her pain, he decided to think twice and re-examine her. Then he told her flat out that they can try 15 sessions, and they can continue if her body responds, but he cannot guarantee it. My mother, of course being as desperate as she was (and she also has a little bit of childlike naivete and she tends to err on the side of trusting strangers anyway ha....but I'm glad it worked out for her in this case!), she said okay. But only a few sessions later, her body started responding, and what's even funnier, she said it seemed like he was even more excited about it than she was! I moved back to California about 2 months after she started with Dr. Yun, and I've been going with her when she gets her treatments. Honestly, I actually wanted to check him out for myself because my mother tends to trust too easily, get overly optimistic, and then get disappointed later. (It's that childlike naivete backfiring.) But I was so impressed - even touched - at how attentive he was to her. I also began asking questions and telling him some of her complaints that she would forget to mention, and he would take all our comments into consideration, genuinely answer all our questions, and keep making adjustments to her treatment accordingly. I love that he stays acutely aware of how her body is changing and makes ongoing adjustments as she progresses. So now the conclusion: how she's improved so far. He's given her treatments to bring down the swelling in her right knee to about half its original size, if not more. He's also been giving her strengthening exercises to rebuild the muscles in her legs. She stopped walking with her cane about 2 weeks ago (so about 2.5 months into her treatments with Dr. Yun). She would be in the most pain first thing in the morning, so she used to roll around in her desk chair to go to the bathroom and move about for about half an hour to an hour before she can even attempt to walk, but now she can start walking almost immediately after getting up in the morning. She's still got quite a ways to go, but these are HUGE improvements in her quality of life!!! Oh, btw, I also started getting sessions with him too :) read more

I have had a lot of success with Dr. Yun's help. I first started going to see him September, 2007 for a problem with pain in my hand and right arm. I couldn't lift anything, even my coffee cup! After he spent time consulting with me and having tests for nerve damage, xrays, etc. my medical doctor and Dr. Yun determined I had carpel tunnel. Dr. Yun started with the adjustments that made the difference. Almost immediately i felt relief and went through further treatment to relieve the pain. I have been seeing him for an adjustment monthly and have avoided surgery that was recommended by my medical doctor. I then started having difficulty with my right leg with pain that would not go away. It went all the way down the right side to my ankle. This made it very difficult to walk and especially to get up from a chair. Once I got walking, it seemed to do much better. Dr. Yun had me get an MRI which showed some degeneration in my lower back. He suggested we try Spinal Decompression for several sessions in a short period of time and then continue with aftercare to increased time between each session. Immediately, I felt relief right away and have not had the pain and continue to do just fine. Or course, I continue with my floor exercises and additional follow-up treatment to avoid any surgery possibility. This has made a big difference for me in how I function and feel on a regular basis. The most recent success is a numbness in my right hand. With extra care on my neck, we now meet once a month to do minor adjustments and I am walking without pain, no longer have trouble associated with carpel tunnel, and no numbness. I would highly recommend Dr. Yun for many problems. He is very careful to check everything before recommending treatment. If it's not possible for him to help, he will always refer back to the medical doctors. You can't go wrong! read more

dr yun was less than truthful when i saw him as a patient for a severe back and neck injury! he blatantly lied to me about my injuries, he also referred me to his attourney friends, who were very unprofessional! so unprofessional, that i had to have the attourney withdraw my case as my lawyer..again..these fraud lawyers were referred by dr yun! he then told me, since i was having so many problems with the less than honest attourneys for my neck and back injuries and problems, that he would not be billing me for the few sessions i had had with him! this was untrue! years later, i pull my credit report and see there is an outstanding bill balance for prima chiropractic group! dr yun put an amount that he never told me about on my credit report! now i have to write to all the credit reporting agencies to get this removed from 2009 its been on my credit report! i never got a letter, a notice or anything beforehand to warn me of this or never given a chance to resolve it! i think thats pretty shady dr yun! you lied to me! you told me if i dropped the case with your lawyer friends, that you wouldnt bill me for the few times i saw you since i was droppiung withdrawing the personal injury case! shame on you dr yun! now i have to go through all this trouble to get this off my credit report! watch out all, he is less than truthful!!! I will be reporting him and giving reviews to the BBB and Consumer Affairs and everyone else I can tell about this horrible experience! Thanks for Nothing Yun! I ONLY HAD 3-4 VISITS WITH YUN AND HES BILLING ME OVER $2500!! REALLY! BEWARE OF HIM! read more

I first came to Dr. Yun years ago to alleviate pain from a debilitating pinched nerve that was causing excruciating sciatica. Several doctors were not able to address the painful condition. Dr. Yun helped me then, and has since rehabilitated me through a couple of auto accidents. Dr. Yun's care is thorough and he explains the reasons for his treatments and recommendations. If it weren't for Dr. Yun, I'm certain I would not be functioning as I am today. I've tried a couple other Chiropracters over the years just because they were located closer to where I work or live, but I keep coming back. It's worth the drive to attain the best care. Now I won't even think of going anywhere else! I know I have found an excellent doctor that truly cares about my health and well being. read more

I came to Prima Chiropractic 5 years ago, right after my ortho doctor advised back surgery. Because of the wonderful care I have received from Dr. Yun, I have not had to do the recommended back surgery. Dr. Yun always takes as much time with me as is needed, explaining what is causing my pain, what his treatment is doing, and helping me to modify my daily life to help me help myself. Dr. Yun always tailors my required number of visits to my condition and progress, decreasing them when I am ready to come less often. He takes the time to know exactly what is going on with me. The staff at Prima truly feels like family! They are fun, helpful and always put me at ease. I would recommend Prima Chiropractic to anyone. The experience is uplifting emotionally and physically. read more

I first heard of Dr. Yun by a good friend of mine. My friend was in a bad car accident a few years ago that left him with uncomfortable back pain and Dr. Yun has helped heal him. He is now in good shape thanks to Dr. Yun. I too was in a car accident a couple of years ago & my friend recommended Dr. Yun to me. I was very satisfied with my treatment. Dr. Yun is very professional & genuinely cares about his patients. About 5 months ago I was in another car accident and immediately made an appointment with Dr. Yun. I knew he was the doctor that could help me recover from the pain the car accident had caused me. Dr. Yun, as well as his staff are great people and I always recommend him to my friends. read more

I found Dr. Yun after not getting any help from two other chiropractrs for my severe back pain. I am sure glad that I did. I was having severe back pain that was shooting inot my right leg. I couldn't even get in and out of my car and couldn't sleep. He is totally different from other chiropractors - he actually does a complete check up to find out what you have. Tells you exactly what you have and fixes the cause. He takes the time to explain my condition and what it would take to get rid of it. He also gives you things, what to do's and not to do's and exercises at home so that you can take care of the condition. Don't look anymore - I highly recommend Dr. Yun. read more

I have scoliosis and had chiropractic treatment from a different place, but no improvement occurred. I finally decided to try out a different place 2 years later when I found prima chiropractic group. Dr. Yun has been so helpful in several ways. Not only has he aligned my pelvis and stabilized my back in a matter of a few months, he also has been extremely helpfulafter my mom and I got into a car accident soon after. Prima is helpful, kind, and Dr. Yun definately knows what he is doing. Right when he saw my condition, he told me exactly what I have and how he planned to heal me. I am so so thankful to have met him! Otherwise, who knows how my body would be now. read more

High recommend!!!! If you want to get better, see Dr. Yun. A friend insisted I try this chiropractor. The doctor was very knowledgeable about my complaints. Other doctors could not fix my problem so i decided to try Dr. Yun. He was thorough in his examination and was able to relieve my pain immediately (whereas the last doctors did not even determine my condition and could not help me). Dr. Yun explained in detail why and what is causing my problem and proceeded to give me treatment. I wish i had not wasted my time and money at the other 2 places. I am no longer in pain. For his care it is well worth the money. Not all doctors are created equal. read more

I first came to Dr yun from an auto accident. He helped a lot. After I was done my treatment I never heard from the doctor or the office again for any payment , it was all handled very smoothly. I guess unless you want to get free medical care and knowing you're just out to cheat an insurance company then you would make bad comments about a doctor or the office when they should get paid. No one wants to work for free and a SCAMMER never wants to pay. In the last 10 years I have seen Dr Yun on and off whenever I'm feeling pain. he is a miracle worker when I am hurting. read more

I found Dr. Yun through my insurance and boy am I glad about it!. I love the quick manner in which the patients are treated , you do not have to wait much time in the lobby before you are assigned to a treatment room and get going with the treatment to the road of healing. Very knowledgeable , tells you what you need to know and what will be expected from you to speed up the healing process. Very honest person , great human being and much better doctor. I am glad I found him and will come back to him if I ever ( God forbids)get injured again Thank you Dr Yun!!! read more

I had a fabulous session with Susanne yesterday. The best massage for a great price. Susanne and the staff are wonderful and nice. I saw doctor after my massage for an adjustment and felt amazing. I find Dr. Yun to be very personable and easy to talk with. Despite the fact that he has a very busy practice, I feel that he takes a personal interest in my treatment. He is always aware of where we are in the treatment plan. Dr. Yun is definitely the best chiro. Wouldn't go anywhere else for my treatments. read more

For at least six months I was suffering neck pain and I wasn't even able to move my head side to side without pain, I tried many things before going to see a chiropractor and nothing worked , I found prima chiropractic group and I highly recommend that place because this is my 4th session with doctor Yun and I can feel a great difference now. I can finally move my neck more without feeling the pain I had in the beginning , Also his staff is very friendly . read more

I feel so much better. Highly recommend this office. The staff is very helpful and the doctor understood my problem and initiated treatment and after seeing him I am doing great. I went to another office on a whim, for this same problem, thinking all chiropractors are the same and I can get help from anywhere. However, I quickly realized I was wrong. and that is why I came back here. I am reminded of the superb care I received before. read more

Probably one of the best Chiropractic clinics out there. The staff is very kind and helpful. Dr. Yun is very informative and will explain anything you ask him. Ive had lower back pain on and off for years now and I was going to a different chiropractor for help but nothing would get fixed. After I started getting to prima chiropractic group I've been getting fixed up with the symptoms disappearing. I would recommend this place to everyone. read more
