Bret Duff

I am a 1997 graduate of Duncanville High School where I played football, baseball and was a member of NHS.  Bob Alpert was my Coach in '97 on the first 10-0 Varsity Football team at DHS (We lost to Lewisville also 10-0 in the 1st round), very sad.   Bob Rombach was my baseball Coach and we were Regional Finalists also in '97. I graduated college at Southwest Texas State University with a bachelor's degree in Exercise Sports Science and a minor in Psychology.   This is my 13th year teaching and all of them have been in Duncanville ISD.  I am very passionate about kids, teaching, and coaching.  I Love seeing students be successful and Really Love when former students come back to share their success stories.


I have been married to Genny Duff for 9 years.  We have three daughters as of this Summer!  They are Ashton-17, Dani-5 and Jett who was born on 6-13-18.  We also have a dog named Lola.   They are the Best Things that Ever Happened to me!!!

I Love being a Dad, Husband, Teacher and Coach!
