Mr Grehan ran the computer club in Belvedere during the 1980s, giving his time in the evenings to allow those of us of a "technical" (i.e. nerd!) nature to pursue our hobby. Along with many in my year, this led to a great career in IT. I learnt a lot in Belvedere, but Mr Grehan's dedication had more influence on my life and work career than anyone else. A truly good man, who quietly but with great care helped those students who needed his gentle guidance. Thank you, Michael.
Michael is a great teacher, both students and other faculty members have great respect for him. Thank you for educating me Mr. G.
A very helpful and kind man, who got me from inter-cert science on to getting an Honours degree in Science. He liked to say "wow" and "That's amazing!". My favourite teacher in my 10 years in Belvo.
Enjoyable class but is too carefree. Needs to be tougher with students and administer tough checks. That said, extremely dedicated and caring, and is definitely a teacher you wouldspeak to as a friend
thought he was a really good teacher. enthusiastic about his subject matter. did computers for us c. 1985/6, pioneering I think.
A true Gent. Committed to his students both during and after leaving Belvo, A very good man++
A very pleasant man, committed to his students 100%. Has a natural love of science. Loves to say WOW, and Thats Amazing!. Great man.
Very decent and committed teacher, though I did not like science. That said I really got into the 4th year science project he set.
Helped our class after two disastrous years of Science...good teacher
one of the most caring teachers in the school.loves his subject and it shows.gotta get some trendy slacks and sandals though!
My fave and best teacher, next to JT. 2S loves ya, baby.
Really cares about his students, and he's seriously mad about science - just look at his Periodic Table tie!
A very diligant teacher, cares for his pupils greatly. You gotta respect his love for astronomy!
Sometimes difficult and treats some older years like junior cycle students but a good guy and a good teacher.
