in all my year, Dr Hoshazaki is the most thorough, thoughtful, and attentive physician I've ever worked with. and I trust him and his judgement.

July 28, 2020 7:55 PM

I am grateful that he calls back very promptly and I'm very grateful that he call post-appointment to check and see how I'm doing. thank you!

July 28, 2020 8:20 AM

New patient appointment and was able to get an appointment within reasonable time. The staff and doctor are all very friendly and I felt very comfortable going over my entire history.

July 28, 2020 8:20 AM

I like that my medical records were mostly already available to his office before I came for the appointment. The integration of records was a very nice move. I also appreciate the portal where I can ask questions that are not urgent. The doctor does not hesitate to call me to explain something. Overall VERY happy I chose this doctor for my care! He listened to me and my niece, and not once did I feel like a burden to him or his staff when I questioned something. Most importantly, as an older gentleman, everyone in this office spoke to me directly about my health and not to my family member that brought me to the office. That respect is important to me. if I needed my family member to be involved, they asked me first. It is difficult getting old, and for people to assume I am not of sound mind is an insult. This office never made me feel incapable of understanding my healthcare.
