Calvin Chien is the most intuitive, talented and hard-working healer I have ever met. He knows what needs to be done and he just does it — and with great efficiency and joy. Resolution of some of my physical pains / issues was immediate; other more chronic issues I will continue to work on with him and I’m confident he will help get me there. This man isn’t selling anything - he is working right away to heal you. Incredible experience.

⭐⭐⭐⭐⭐ (Google Review) 
Dr. Chien is a true healer! I had doubts, but after seeing my husband's condition improve after 1 month, there was no denying Dr Chien's skills. I have sciatic pain that radiates from my right butt cheek down to my toes. This pain would come and go and at times was so painful to the point of tears. My PCM insured me there was nothing that could be done and advised me to take extra strength tylenol. I decided to try acupuncture here back in May 2019 and after 1 treatment my sciatic pain was gone, and til this day has not returned. Thank you Dr. Chien!.

⭐⭐⭐⭐⭐ (Yelp Review) 
I have used Dr. Chien off an on for over a decade. His knowledge and expertise is unmatched in the USA practically, let alone in Colorado. He has always been a great source for herbs and treatments when you want to get away from the nonsense of modern doctors and be healthy. I highly recommend him.

30 Years of Master Tung Clinical Studies

As a third generation acupuncturist Calvin Chien had an extraordinary opportunity to study under Master Tung’s disciple Dr. Lin Chi-Sun for 10 years and learned the guarded secrets of Master Tung acupuncture points.  Master Tung’s acupuncture points are known worldwide and commonly referred to as magic points due to the instant and lasting results.

After 30 years of clinical study in Colorado Springs Calvin Chien is extremely proud to present over 40 years of his knowledge for the first time in english for practitioners and followers of acupuncture to better serve their patients in a profound and lasting way.

“Exactly what I was looking for. This book is absolutely beautiful. It’s easy for the beginner to read, understand, and follow…..the PERFECT pictorial atlas of acupuncture points. Not only has a description of each acu-point, but also has 3 different illustrations: graphic, overview of channels, and a photograph showing the acupuncture needle in position. I cannot say enough about this book.”
