Mr. Diffin

Hello Patriots,

My name is Dean Diffin and I am the department head for social studies here at Centennial. This is my 17th year here at Centennial High School and my 18th year in the West Ada School District.  My wonderful wife Leslie works in Special Services here in the West Ada School District.  I have three beautiful daughters Sophia 13, Gracie, 11, and Maggie 5.  I earned my Masters Degree in Educational Leadership from the University of Idaho in 2009.  I went to Ed school and received my bachelor's degree in social science from Lewis Clark State College.  I am the Head Softball Coach here at Centennial. CHS is a great school and I wouldn't want to teach any place else.  I grew up in north central Idaho and graduated from Kamiah High School in 1987.
