I am sorry to hear that Iseri Sensei has died. I studied with him when I was in high school, years ago. Although I moved away from the area after that and I have not seen him since, I remember feeling that he was gentle, patient, and skilled. At the time, it was the only dojo available under the circumstances. Every dojo I had experienced had been a joy to study in, and his was no exception. I only learned later, after some lesser experiences, how fortunate I was.
