From our patients


Melissa Gebardt Tsai, PA-C takes extremely good care of me. She is on point and always friendly. I have always been impressed with Dr. Crandall and his whole team. I am progressing nicely from my 3rd back surgery that was just completed in December (first one done by Dr. Crandall) and look forward to finally being pain free. I would recommend Sonoran Spine to anyone!


Dr. Datta,

Thank you sooooo much for the successful surgery that you performed on my back. The pain is gone and I am on the road to recovery. You and your staff are top notch professionals and I have already referred three people to your practice.

I Love Sonoran Spine!!!

Dr. Chang is incredibly knowledgeable in his field of expertise. My orthopedic surgeon referred me to Dr. Chang due to the complexity of my condition. Dr. Chang came in the room and explained everything to my husband and I with confidence, compassion and in a way we can understand. I cannot give him enough stars. His office staff deserve five stars as well. From the front desk to radiology to the nurse. I love Sonoran Spine!!!

Absolutely wonderful care. Dr. Crandall addressed all of my questions and treated me with the utmost compassion. After having the recommended surgery I felt much better than before the operation. Thank you Dr. Crandall and Sonoran Spine for giving me my mobility back!
