Hello, I’m Martin Castro and I have been Swanson Elementary’s Principal since 2022 and served as the Associate Principal beginning in 2019. I love leading educators that are passionate about changing kids’ lives!

I earned my Bachelor's (2008) in Psychology and Master's (2012) in Educational Psychology from UW-Milwaukee as well as my MBA (2012) in Educational Leadership from MSOE. Currently, I am pursuing my Ph. D. and Superintendent Licensure through Cardinal Stritch University. Prior to Elmbrook, I worked as a school counselor at Oak Creek-Franklin School District for 7 years and 6 years as a Lead Counselor within a residential treatment center for WellPoint Care Network (previously known as St. A’s).

Swanson is well-known for having dedicated staff that absolutely love kids and makes sure everyone feels welcome. We are a vibrant learning community with professional staff committed to making our school an exceptional place to learn and work together.

Outside of school, my wife and I have three children and in our spare time, we enjoy engaging with our church to give back to our community. I grow up playing soccer which afforded me the opportunity to play in college highlighted by winning a National Championship in 2009 with the Bavarians Soccer Club.  

I would be happy to share more information or answer questions about Swanson. Thank you for visiting our website!
