I saw 3 other surgeons before seeing Dr Koo. Dr Koo was the only one willing to operate on my terrible spine condition. He was very careful and meticulous and ordered all the tests and that's how I knew he was going to be great. The whole surgery process was long but well worth it at the end. Dr Koo gave me a new life I haven't had in the last 20 years. I had my last checkup with him today and he told me I have graduated. Thank you Dr Koo.

Dr. Koo is the best ortho surgeon. He took my dad in right away for a discectomy. Answered all our questions, great bed side manners and my dad felt at ease knowing he was in great hands. Very empathetic and caring. Would recommend Dr. Koo to everyone!

Dr. Koo lacks empathy and has a big ego. I brought my daughter in with excruciating pain on her scaphoid bone. He didn't examine her or show any care. I'm now going through my family dr to get further assessment. Do not trust his opinion!

Do not trust dr. Koo. He lacks empathy to his patients. I brought I daughter for a broken scaffold bone and said showed a shadow and a Crack. He said it was a sprain. Don't trust his opinion!
