DOB was brilliant he was my tutor for two years great lad threw me out once but still you have to love him
sound and always up for a laugh. loses control thouh too much to the detriment of the learning environment
David has a outstanding knowledge of his subject and makes his classes interesting and enjoyable. Downside - but tends to lose control class, effect the whole learning environment.
I am a past student and Mr. O'Brien was one of the best teachers there, always looked forward to his class, he made maths interesting!
best I.T. teacher of all time.his brilliant 'close the programme and log off' phrase will always echo through the walls of S7
a decade on, and i still think he's a an all-rounder, great fun, should be in a comedy club..class act., thanks 4 the great memories....
Funniest man alive. Straight shooter and always in good form. Loved maths with him
lads they arent just asking if hes cool do ye honestly think he is a good maths teacher.maybe if u looked at the results his leaving certs get u wud see
What a man! great teacher who'll have a laugh with you aswell. Thanks for all the memories.
he is such a legend if you didnt think he was funny you were probably a troublmaker
Ah he's sound out but he always had a lot of trouble controlin the class
whoever wrote the last comment is a muppet. Mr. O'Brien is COOOOOll!
No consideration for students,talks to himself about students in front of students..is generally a bad teacher
