I had a horrible, white hot burning pain in my leg from sciatic nerve problems, and after one visit to Dr. Yu, it went away, never to return again. Granted, I needed a lot of work done to get me back in line completely, but seriously, I never had the horrible pain I had been experiencing after that first visit. Dr. Yu explained everything to me quite thoroughly, as I didn't really know anything about chiropractic treatments, and made me comfortable about the whole process. I was HAPPY to drive to Millbrae from Sunnyvale twice a week to get adjustments done, because I felt great getting them done. I only did the twice a week thing for a little while, however, as my back started getting better and better, and so we were able to stretch the time in between appointments until I was going once a month. Sadly, I changed jobs and now have longer hours, and am no longer able to make it to his office for adjustments. I have not yet found ANYONE who compares to Dr. Yu. He is fantastic! read more

This practice is really convenient for me. Whenever I feel tight or in pain, I just pop right in for an adjustment and 5 mins later I'm brand new. read more

The best. Came in barely being able to move my neck for three days straight. Woke up the next morning after an adjustment with Simon...and as the day has gone on, I feel increasingly better. He is so knowledgeable and is very passionate about what he does. He knows what he's doing and I wouldn't trust my chiropractic needs with anyone else. read more

I have been going to Dr. Simon with my back problems for 5 weeks and I must say that he has done a wonderful job curing my back. He is very knowledgeable about the spine and rest of the body ligaments, take special interest in pinpointing your issues and the treatment. If you are looking for a Chiropractor, I highly recommend Dr. Yu. read more

Simon was a great help in relieving some pain I had in my chest area where my spine/rib was out of alignment. His calm and friendly personality made treatment interesting and enjoyable. I live down in the South Bay so the drive to San Bruno can be long but it's worth it to go to a chiropractor that you can trust. I would most definitely recommend Simon to anyone. read more

Before seeing Dr. Yu, I had never been to a chiropractor so I wasn't quite sure what to expect. What I discovered was a wonderfully caring and knowledgeable doctor that helped me recover from a neck discomfort. He identified the problem and thoroughly explained the causes and effects. He then put me on a regular schedule of visits for adjustments and after each one, I felt more loose and relaxed than ever before. Dr. Yu was always careful to explain what he was doing and then very precise in his work. I highly recommend Dr. Yu - you won't be disappointed. read more

Dr. Simon Yu is awesome!!! I had a pinched nerve radiating down my right arm from back to R shoulder. I literally couldn't do much and was very limited in motion, it didn't help having a four month old baby either who loves to be held. Couldn't jog, do my daily chores, state of mind was a little bit off (because I didn't even want to go shopping!), etc. After a 2-3 appointments with Dr. Yu, I was well adjusted and back to normal...imagine eight weeks of suffering. Tried physical therapy, acupuncture, massage therapy, etc - none worked, though the massage may have helped a bit. I highly recommend Worldwide Chiropractor (even those skeptical - he will truly help you feel better). read more

I love him. He's sooooo cool and down to earth. Like everything about dude. The service is superb. The two youngins at the front desk has the greatest attitudes and are so friendly. They remember your name. I never had no long as wait. Sometimes I would walk in and before I can sit down Doc like you ready Crystal. Love this place. If I ever needed a chiro again this will be my go to and hope your too. If my review leads you to him please mention this review. read more

I've been getting adjusted by Dr Simon for about 4 years. I suffer from chronic, debilitating back pain that often results in extreme headaches. Dr Simon always helps my pain. I see him regularly for maintenance, and it has helped keep my aligned and keeps my headaches away! Plus, Dr Simon is just an awesome, amazing person with a healing, zen vibe about him. read more

Simon and his entire staff are first class. He goes above and beyond for his patients. I trust him 100% and feel like he dedicates his life to helping others. He always looks at innovative techniques and has a great sense of how to help the whole person- Body, Mind and Soul. It does not hurt that he his a great person either. I highly reccomend Worldwide Chiropratic and Simon Yu for all your Chiropratic needs. read more

The nicest chiropractor and the best. My husband was in pain and called Dr.Simon in the morning 7am to make an appointment. He answered the call and told us that he was about to leave out of town but if my husband could arrive in an hour, he would wait. Oh..... at 7 am picking up a patient's call and took him in is soooo much appreciated for someone who was in much pain. Thank you Dr.Simon for saving my husband otherwise he wouldn't be able to work that day and he would be so much in trouble. read more

I've known Dr Simon since we were in high school- just about 20 years. He's not only my friend but my doctor as well. I started seeing him after a major car crash where I rolled down the hill of 280. I was in tremendous pain and while it took months- Simon really helped put me back together. I also highly recommend him if you are pregnant. Through my 2 pregnancies, Dr Simon has helped me relieve the pain from my lower back and hips. And suggested many exercises/ stretches to keep my body ready for delivery. He's really concerned about his patients and is always looking out for their best interest and care. I would and have recommended him to all my family and friends. read more

Dr. Simon Yu is the best chiropractor I've had. I've had other chiropractors try to adjust me and I just tense up. He's the first to take the time to figure out the best way to adjust me. His treatments are great and the nutritional advice is an added plus. His staff is professional and courteous and very accommodating. Thanks Dr. Yu! read more

Dr. Simon has been helping our family feel better for years now! We are all so happy with his keen understanding of the human body, how good spine health affects all other areas of your body and even how to just really listen to his patients. He really treats us all like family. read more

Superduper... Been getting help since 2004. As a disabled army veteran i really appteciate you and the help i recieve.

Dr Simon, has been a life saver for me. Totally trust him with his skills. I drove for 50 miles just to take treatment from him, even though the place I live has many chiropractors. Do yourself a favor and make sure you see Dr Simon for your problems. read more

I have been a patient of Worldwide Chiropractic for 8 years - since the office was in Millbrae. Dr. Simon is the ONLY person I will let adjust me (and I had been to other chiropractors in the past). He is a fabulous chiropractor and a wonderful individual. I have referred numerous people to visit Worldwide Chiropractic and we have all been treated with respect and dignity - from the frontdesk staff to our one-and-only chiro! Dr. Simon does more than a quick crack of your neck and/or back. He asks what is going on with you; tells you where you are out and how to help avoid going out in the future; and he has an extensive knowledge of nutrition and holistic health. You can also book a massage! I would and will continue to refer anyone who needs an adjustment or even an assessment to Dr. Simon at Worldwide Chiropractic! 100 out of 100! Thank you Dr. Simon for always "keeping me in line!" Thank you read more

I refer all my family and friends to Dr.Simon Yu, I have found him to be a expert practioner and a kind and understanding man who values his family and community. He and his lovely wife Rosalyn are very involved in the community and give freely of their time and energy and services and did a lot to help the victims of the fire in San Bruno read more

I have to admit that i've been very skeptical of Chiropractors mostly because I just never knew what to expect and what they could or could not do. After looking through Yelp (thank you!) I decided to see Dr Simon to address a long standing neck pain since my surgery two years ago. Dr. Simon addressed the pain with simple adjustments over a series of months and slowly but surely, my body started to heal itself as he said it would. After nine months, any indication of that pain which many doctors could not address has all but disappeared and eventhough he recommends coming every so many weeks, I still find every opportunity to see him every week, religously. I've a believer!!! read more

A year ago I was in a car crash. Since then I have been to a bunch of different people for my chronic neck pain and headaches. There have been few people who I felt made a significant difference. Jeanelle Diaz was one of them. Her hands were soft as pillows and always found the right spots. She really made me feel like one day I could be pain free again. Even though she is young, her hands feel like they have been doing this for generations. I would definitely go back. read more

I actually used to laugh at the idea of chiropractic. A few months back I slipped down some stairs while carrying a gun safe on my shoulder. It took many months but Dr Simon all but reversed the damage I did to myself during a clumsy fall. As a contractor once in a while I tweak my back. I make an appointment as soon as I possibly can and Dr Simon straightens me out before my back can get so tight I can not work. Thanks for taking care of me Dr Simon! read more

Dr Simon is a fine doctor, but I stopped going to him because he did all of the talking and none of the listening. After seeing him 2x a week for over a month, he couldn't remember how I had gotten hurt or that I had just had a baby. However, I knew EVERYTHING about his father's club, his business, his parents, his parents' food business, his exotic meat club BBQ, and his kids. While interesting, I prefer a practitioner who listens, and remembers why I'm there. read more

I started going to see Dr. Yu early on in the 3rd trimester after my OB recommended going to see a chiropractor specialized in Webster's Technique, to help get baby into a good position and help with preparation for labor. I found Dr. Yu in the Bay Area Birth Information Directory. My main reasons for choosing him was because they would take my insurance. Dr. Yu promised to help me get prepared for labor by practicing Webster techniques and ensuring that broad ligaments were not too tight and such. I soon discovered that Dr. Yu is a chiropractor "who also" does prenatal. a) He doesn't take enough time for his patients, appointments last about 5 to 10 minutes. I spent more time driving to appointments than attending them. b) For prenatal, he is not gentle. Each appointment consisted of cracking my bones into place. This is too harsh of an approach to prenatal care, because pregnant women have a hormone called relaxin in their joints which makes them overly pliable. c) He doesn't take time to ask you how you're doing, so he basically doesn't have time to assess you for any problems at each appointment. d) Even though he promised to proactively help with baby's positioning, he did not practice Webster's at each appointment. He was also quite rough on the muscles, so it usually hurt when he applied pressure. e) This is subjective but I think the cracking bones made my baby feel unsafe and she never got head down and now I'm due for C-section. I can't speak to other kinds of care, but if you are looking for prenatal care, you want a doctor that will take the time to see you, for at least 30 to 45 minutes. Most treatment should be done on soft tissue (muscles and ligaments). My baby was never acknowledged during any treatment. He didn't seem to know anything about "palpation" (checking baby's position) which suggests prenatal isn't a true specialty of his. Last, I was never offered help up from the table--pregnant women are carrying a large load and do need a bit of help up, you know. After seeing a specialized prenatal chiropractic practitioner only twice just recently, I got quicker relief because work was done directly on the muscles and joints that needed work, and the Webster's technique was applied every time. I do not recommend Worldwide Chiropractic for prenatal, Dr. Yu needs to get to know midwives, doulas, and others in the birth community more seriously and understand the needs of pregnant women beyond general chiropractic are before he can truly say he is Webster's certified. read more

great practice very knowledge and professional manner. it may not feel a dramatic change but for ones who suffer the long term condition can definitely appreciate the graduate improvement. read more

Simon Yu is brilliant! He's helped my husband a lot with his sciatic nerve pain and he's also helped me with my ongoing neck/shoulder pain. I appreciate his input and advice about how to maintain good posture and health. The appointments are very effective..just a tad bit short in my opinion. Sometimes I feel a tiny bit rushed. Unfortunately, our rates went up with Kaiser, so I've had to cut back but I'd recommend him to anyone I meet that needs a chiropractor. read more

Dr. Yu is a miracle worker! I have double scoliosis and neuropathy which can cause incredible pain. I was in intense pain, the worst ever, and was using a cane, which I have never done before. After four treatments by Dr. Yu, I felt about 30% relief. Dr. Yu suggested I try lidocaine and motrin injections given by the office nurse practitioner. Now my pain is about 70% gone. Dr. Yu noticed I was walking around the office and had forgotten to use my cane! I am so grateful for the treatment I received. read more

The office and staff is fantastic. Dr. Simon makes you feel appreciated and completely at ease with any medical issue.

Dr. Simon Yu is an incredible chiropractor. His knowledge and demeanor inspire both trust and confidence. He takes the time to explain fully and listens attentively. A rare combination. I've always been afraid of chiropractic care, but Dr. Simon changed my belief. I am only sorry that I didn't start seeing him sooner. read more

Needed some neck/back care after someone rear ended me. Was very helpful in every possible way. I would recommend Dr. Yu to anyone. Thank you! read more

I went to Worldwide Chiropractic for a girls night out for a school fundraiser where I was able to try a mini foot massage and ear acupuncture. It was a great way to socialize and get my relaxation on all at the same time! I enjoyed my foot massage and acupuncture and I want to go back for an adjustment with Dr.Simon. :) read more

When Dr. Simon adjusts me, I involuntarily smile. I walk out not realizing how good it's possible to feel. Dr. Simon is friendly, patient, a good listener, creative and intelligent. He will do what it takes to make you feel better, inside and out. The office staff is helpful and friendly as well. Can't recommend them highly enough!! read more

In the spirit of full disclosure, I must say that Dr. Simon is married to my cousin. However, I also have to say that he's the best chiropractor I've ever been to. I have problems with my hips and lower back to the point that I can barely walk at times. Since I've been going to Worldwide, I've been nearly pain-free in that area. He's also helped me with some other health problems. I cannot recommend him highly enough. read more

My family and I have been using Simon Yu as our chiropractor for over 3 years. Our relationship began when he and his wife were my patients and delivered their baby at my birth center. Then my son in law needed treatment for a severe neck issue and Simon proved to be the first and only person that could help him. After that, my daughter consulted and worked with him due to a shoulder injury she sustained as a dancer and acrobat 12 years earlier (as a teen). She had tried other chiropractic care without sucess but Simon was able to help her. I began seeing him after injuring my neck. I took my grandchildren on a ride at the Arizona State Fair and really regretted it! I had never myself had chiropractic care (even though I prescribed it to patients and family very often). I just had never needed it up til then. Thank God for Simon's skilled and strong hands! He hepled my neck injury and up til now it hasn't recurred. I have used him for other things periodically. He has also adjusted my grandchildren. He currently serves my clients at the Birth Center (free of charge) once a month and many go to his office for care as well. Simon and his wife had a second baby with us 19 months ago. Our practices compliment each other prefectly! Judi Tinkelenberg CNM read more

I have been a patient of Dr. Simon for the last 6 years. He has helped me in many ways. The one problem that stood out the most that he has helped me with, is my herniated disc's. Once I had a huge huge sharp pain in my back, in which I couldn't walk or stand. I could not move or anything. Tears were popping out of my eyes. I had a charlie horse lasting for 24 hours and it just didn't stop...my sister had to massage it all night long. I could not lay down to sleep, I had to sleep in a sitting position. My sister drove me to see Dr. Simon for two days straight after that and it eased the pain tremendously. The relief that I got was so great...I felt SO much better. It is really indescribable. Now, that I have been working on my back in different ways, through Yoga and I still see Dr. Simon for adjustments. I can feel when I am out of alignment and once I go in for my adjustment, everything is just better after wards. THANK YOU VERY MUCH DR. Simon. read more
