Great hip replacement experience with Dr. Bob Yin and his PA, Jon Onosaki.

I wasn't completely comfortable with the PA. His exam was good but I didn't like his attitude toward my shoulder issue. I did like the fact that he ordered an MRI. He was too abrupt for me, I didn't care for his bedside manner.

Jon Onosaki is an excellent PA. I saw him for my 7 week follow up on my hip replacement surgery. He reviewed the Xrays with me, examined me, watched my walk and make certain movements with my leg. He answered all of my questions completely in an easy to understand manner and was truly concerned for my health, my understanding of my current condition, and my concerns going forward. He is to be commended for the professional way that he does his job. After I left I thought of another question that I needed to ask him. I messaged him through My Chart late that evening with the question. When I opened my email in the morning my answer was there in My Chart and told me exactly what I wanted to know. He is an asset to St. Jude.
