Degrees and Certifications:

Mr. Addabbo

KI graduated from West High School in 1977 (long time ago). The first president I voted for was Ronald Reagan in 1980. The day after I got married, Mount St. Helens erupted. The year I earned my undergraduate degree, "Raiders of the Lost Ark" was the summer blockbuster and Rick Springfield released "Jessie's Girl."  The year I got hired (1984) at Deer Valley High School, Carl Lewis was winning gold medals in the summer Olympics in Los Angeles and Ghostbusters was showing on the big screen.
I am a math teacher, I love math and teaching.  I hope that your time in my class is more than enjoyable. 
I did my student teaching at Deer Valley in 1983.  My seniors from that class are turning 53 years old this year.
My three children are all Deer Valley graduates.  Beth in 2007, Tim in 2010 and Joel in 2012.
This year I am fortunate enough  to  be the starter at  all home swim meets, announce home varsity softball games and referee track meets.  I am especially excited that I get to announce all home varsity football games.  No lie, I bleed blue.  Go DV!
