Cahill Judo in San Bruno Ca for beginners?

watched a class the other night ,,seems like a rough school they were going pretty hard so my question is,, is that school a bad choice for someone my age(40) that is just starting out............ sorry wrong forum can someone please move to judo forum

went when I was a child. my sister cried every day we brought her to that place. I remember liking it more than her but not being really interested in judo at the time (~7-9 y.o.)
