Len Breen, a former pupil wrote:
A great teacher, a mentor, something of a guru, and for me, in my adolescent years, a person who was the worldly big brother or wise father figure that I had missed in growing up. Frank McCarthy was a very clever person, no less for an alienated kid such as me for whom he always had generous time. He brought art and music to my world, one where otherwise such things were fanciful. He, with such grace, engendered self-confidence and self-assurance in me and stimulated and affirmed my inquiring mind. He was a special person for me, but also for a vast number of others.
My most impressive memory of him - a treasured memory - was of the first Student Art Exhibition where I had entered two images. I was summoned out of class to be congratulated, praised and applauded by him for my 'fine works'. I was so apprehensive and timid about entering my paintings and so elated by his actions and words.
