I really appreciate Dr Ishii taking the time to educate me on my conditions and listen to my reports on my body and hearing and believing and trusting my reports of progress and lack of progress with various treatments along with explaining risk associated with treatments versus lack of treatment. I have confidence that my best interests are carefully calculated by this team and it is reassuring to have a doctor who is most interested in my progress with treatments and who cares about my wellbeing and outcome

I have been a patient of Dr. M. Ishii since 2018 when he first met me regarding a rare chondrosarcoma In my right nasal passage. I thank God I was able to get an appointment with him, that he reviewed a CT scan I brought, ordered an MRI and because surgery would be jointly done with a neurosurgeon, he referred me to Dr.[ ]. I have the highest respect for both of them and always get excellent care and guidance.,

I appreciate everything he has done for me.

Dr Ishii is a gem . Very caring and professional. We are so blessed to have him in the medical profession .
- 3 out of 5 starsReviewed on 9/9/2024
He was very intelligent, and seem to know what he was talking about. But he spoke very quickly, almost as if I was practicing in the same field as he he also seemed narrowly focused on just the area where the pain was. I would prefer a more holistic approach.
