What Patients Are Saying About Dr. Chou

We could tell you about our patients’ excellent care, but we know that they can do a much better job. We’ve provided a selection of statements from our patients speaking about their positive experiences with us.

"Your surgery was nothing short of a miracle."
G. V.
"Dr. Chou performed two operations in 2011. He removed osteophytes located on my cervical vertebrae in June 2011 and performed a laminectomy covering L2 to L5 to clean out A severe spinal stenosis condition. It is now late 2020. I am 75, ride my road bike and hike most every day as well as stretch. His work completely turned my life around as I was barely able to walk a block due to stiffness and pain. I cannot recommend Dr. Chou more highly."
Michael B.
"Dr. Chou has magic hands! Took wonderful care of my grandfather. We were so scared my grandfather wouldn't pull through his infection and Dr. Chou did an amazing job taking care of him and performing the surgery with expertise."
