Mr. Joshua Heisdorf

Hello my name is Josh Heisdorf and I have been teaching at Jefferson Elementary since 2015. I have previously taught 4 years prior to joining the wonderful faculty and staff here at Jefferson. I am a graduate of Concordia University.  I enjoy going to math workshops and furthering my knowledge and passion for education.  When I am not teaching I love spending time with my family.  We go on many adventures including visiting the Shalom Wildlife Center, Milwaukee County Zoo, Lego Land, and the Crayola Factory just to name a few.  I am a big sports fan and closely follow the Milwaukee Brewers, Bucks and the Green Bay Packers.  I love to recharge by taking trips with my family up north and taking in the beautiful scenery. One of my passions is baseball as I have played it ever since I could walk and I do spend my summers coaching high school baseball.  I have been coaching since 2007 and currently am the assistant coach for the Mequon Thiensville Varsity Team.
