My name is Gerald Hiesterman and I new here at Scavo. I am excited for my first year at Scavo. Before coming to Scavo, I was the Behavior Interventionist at Amos Hiatt Middle School. I am in my 12th year for the Des Moines Public School District where I also was a Business teacher before becoming the Behavior Interventionist.


When I am not working, I like to spend time with my family and friends. I am married and have one son. I also enjoy cheering on the Iowa Hawkeyes, camping, gardening, exercising, watching sports, and movies.

I am the Executive Secretary here at Scavo, I graduated from East High School and started working in the workforce right after high school when you could still get a job without a college education. I worked in the public sector for about 10 years then I started at Casady Alternative School in 1995, went to Stowe Elementary in 2000 and in 2002 I returned to Scavo High School a couple of years after they merged with Casady Alternative School and were located downtown. What I enjoy most about my job at Scavo is working with the students and staff. Graduation is the best day of the year here.

I have worked in Des Moines since 2005. I started off teaching 7 and 8th grade Literacy at Harding Middle School. I then traveled to Weeks Middle School where I was the Behavior Interventionist. Now I call Scavo High School home. As School Improvement Leader I enjoy working with the students, staff and families of Scavo High School. I believe in our mission to Educate, Advocate, and Graduate all students.


Outside of school I love to spend time with my wife and two sons. We enjoy all things Iowa State and going boating in the summer. I also run a non-profit called the Cameron Carico +10 Foundation in my spare time.


I graduated from Buena Vista University with BA in Elementary Education and received my Masters in Educational Leadership from Viterbo University.
