What's Up! My name is Mr. Demitropoulos and I have been a part of the Mather's Social Studies department for 20 years. I am fortunate enough to be able to teach what I love, and that is Psychology! I also teach Civics and have taught various other subjects during my tenure here at Mather. I love to travel, go to sporting events, see live music and most of all spend time with my wife and three kids. Go Blue! Go White! Go Rangers!
