Very professional! Great person! My 16-year-old son related to him very well. He has an awesome personality and great sense of humor.
So happy that Dr. Chang chose to settle in Sioux Falls so that I can be his patient! Thankful for his care and expertise.
Dr. Chang was very knowledgeable and understanding. A friendly face.
One of the friendliest doctors I’ve ever had. His knowledge about acupuncture is tremendous.
Dr Chang and all the staff are excellent.
I first saw Dr. Chang 14 years ago, I had nerve conduction studies, followed by eight acupuncture treatments, and was pain-free after years of chronic sciatica back pain. I then joined a local fitness center to continue the healing, as I was actually able to exercise again! I have never even had to go back for any more treatments for that health problem! His gifts of healing, experience, and expertise have changed my life forever for the better! He is compassionate, caring, kind, thorough, and so intelligent. I returned to him years later for a very painful neck and shoulder, with the same successful results. I am now seeing him for the third time. Once again for acupuncture for pain relief of a new problem area. All of my three treatment periods over the past 14 years have been consistently of the highest quality. We are blessed to have Dr. Chang here in Sioux Falls. I tell others about him all the time, and try to help promote acupuncture as a viable option for pain relief. I had a “needle phobia” most of my life, so it took A LOT for me to decide to try this. If you are worried about the needles, don’t be! You will be fine!
I had a very informative visit. He was very concerned and wanted to find the problem. I would recommend him very highly.
Super experience every time! Very punctual! Is always polite and willing to answer all questions and concerns! Great doctor!
I travel six hours to see Dr Chang because he is caring, knowledgeable, takes time to explain and makes sure I understand. Answers all questions I might have and I never feel rushed with him!
Dr. Chang listens before deciding what needs to be done. He explains his decision and gives me options. I have seen him several times and he is consistent with the treatment plans. I am very happy with Dr. Chang.
Dr. Chang is fantastic! I went to him for steroid injections and I was very nervous because the previous three times I had them done were with a different doctor at another facility and it was a terrible time and very painful. It was the complete opposite with Dr. Chang though. The whole experience was so much better and it was a lot less painful. Dr. Chang is very knowledgeable and you can tell he generally cares about his patients. I would recommend Dr. Chang to anyone!
Very nice and friendly. Was on vacation from three states away when my back just gave out. They were able to get me in quickly and get me back on the road. Thank you Dr. Chang and staff.
Dr. Chang is an expert at relieving pain! Very impressed with him and his staff.
I’ve known Dr. Chang for some time now due to tests he has run for nerve conduction studies for other doctors at OI. Even when the test was uncomfortable, he made me laugh with his brilliant sense of humor and quick wit. I truly love this man, all medical genius aside. He’d be a welcome guest at my home and table any time. I can never thank him enough for all he’s done for me in my improvement of health over the years since my three head injuries, seizure disorders, 56 major operations and side effects which have come along with them. God bless him and his practice! He’s now working with me in pain relief. Ah… sweet sleep again!
Always happy to be treated by Dr. Chang!
They are the best. Couldn’t ask for anything better.
