Dr. Oishi was my surgeon on my back and did a fusion. He was so wonderful. Great bedside manner. Lots of humor to make you feel at ease. His assistant Shannon was also so great keeping me informed. I loved them both. Also the office staff is very courteous and accommodating. I give the whole group 5 stars and would recommend them to any of my family or friends .

10 weeks out from 3 level fusion . Dr Oishi and his staff from the front office to those I could not name have done an excellent job. The communication levels as well as expectations identified have been outstanding. Maria and Patsy have done an amazing job at keeping me informed and that means so much . Thanks to you all. You have changed my life.

COMPLETE PAIN RELIEF! Thank you for your great care and expertise. While other doctors did not offer me hope or attention to detail, you spent the needed time to examine me and my MRI images. You gave me options. Having surgery performed by you changed my life. I now live without pain, and I thank you. I have referred friends and family to see you.

I had multiple issues--spinal stenosis, bulging discs, sciatica, compressed nerves, mainly on L4 and L5, etc. At first, I had gone to an orthopedic surgeon to schedule the surgery, but because of the nerve involvement, several people suggested that I get a second opinion from a neurosurgeon. I went to Dr. Oishi and was extremely pleased with the results of the operation. He was skilled and I recovered quickly, needed no physical therapy, and am free of pain. I highly recommend him.

Dr. Oishi is an excellent Doctor. I wouldn't want to go to another neurosurgeon. Unfortunately his office staff, primarily Patsy, are all extremely rude and unhelpful. It was only through perseverance and determination that we were able to have Dr. Oishi provide our needed services. Patsy and all staff are awful - rude, unreliable with getting our info and proper codes to BCBS, and simply put are the worst staff I've ever been around, to include United Airlines.
