        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.,

        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.
