It has reached his time to retire, nice man though.
I LOVE Mr. Gillen! He's amazing and a wonderful teacher!
I hope they never fire Mr. Gillen! He should never leave JFK everyone should get the chance to have him for class
Great Guy...Great Class. Hopehe nver retires because JFK wouldn't be the same without him.
Has to be the best by far the best teacher at JFK. He has been there for 40 years. When you thinkof JFK you think Mr. Gillen
Average government teacher. He has some really odd views, probably since he's also the athletic director. Remember potential and George Allen.
