Keystone Reviews

Real stories from patients who found hope through Dr. Shin's Functional Restoration Program

"

This is Denise and I am a former State of CA employee who experienced injury on the job. I have a very caring doctor who sees me approximately every six weeks. He reviews my case and we discuss my progress and/or when progress is not made. He knows my history and keeps track of my appointments to other therapies, follow-ups and makes sure I am always receiving the best care. Thank you, Dr. Shin for your conscientious work and having a vision to treat your patients. And thank you, Dr. Yoon for your consistent and thorough care and comprehensive treatment plans to date; even through surgery and all follow-up care. I am always supported by the great care I get. The staff is efficient and always kind and helpful. Thank you, CIS- Sacramento, CA. In my most recent visits, June 2026, I am still completely and thoroughly pleased with Dr. Timothy Yoon, my pain management doctor who is housed within Dr. Carl Shin's CIS facility, and I am well cared for regarding previous work injuries.

I was afraid I would no longer be able to do any of the things I had planned for my future; the Keystone program and the wonderful people there gave me hope.

I was on crutches for 13 years after a bad accident damaged my spine and neck in 8 places. By the end of the Keystone program I no longer used crutches, was off my medications, and resumed an active life on my ranch.
