Jon Onosaki PAC is the best. He assisted in my hip replacement surgery and conducted all of my follow up exams. Jon called and texted me throughout my recovery and was always available to answer any questions I had. He is a remarkable healthcare provider and I always looked forward to seeing him. He reminds me of healthcare providers in the 1950s and 60s, who took a personal interest in their patients. Thank you Jon.

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.
