Dr Nishioka took the time to ask about my background and answered my questions. He is a very knowledgeable and caring doctor.

Excellent and have had a 30 year relationship.


December 2024

I was treated with kindness and respect by Dr. Nishioka, he was a great listener, suggested some follow up tests, and when the appointment was over, he walked me to the receptionist (holding my coat) and told her what follow up appointments to make! Dr. Nishioka is also a true old fashioned gentleman! He is very polite and well mannered.


December 2024

Dr. Nishioka is wonderful. Although he canceled the appointment I had at first, and then it was rescheduled the day before the visit to become a virtual appointment, which I found awkward given some of the information I had to communicate, he is always, always worth waiting for!
