I want to thank Dr. Michael Chang and his P.A Mara Immediato. Dr. Chang did a Lumbar spine fusion and laminectomy revision on me August 7th. I was suffering debilitating chronic pain for 8 years. I had been in pain management for over 5 years. I had been to 5 surgeons and they all said not to do the fusion surgery as it wouldn't help me. The pain management I was with did every procedure they could do to try relieve my pain, all failed.

I'm so grateful to Dr. Chang for believing that the fusion would help me, he even told me he was 80% sure he could get me to 50% pain relief, and he was right! I feel so much better! I'm 6 weeks post op and I feel better than I have in 8 years. Thank you Dr. Chang and Mara for changing my life for the better! I highly recommend Sonoran Spine!
