Jairo Casco, Principal

My name is Jairo Casco. I am honored to introduce myself as the new principal of Southgate STEM Elementary for the 2023-2024 school year. I look forward to using my educational leadership skills to partner with staff, parents, and community members, in order to provide the best educational experience for our students.

There is a great responsibility to provide the students of our community with an experience that develops the necessary skills to prepare them for success in an ever-changing world. I believe that in order to cultivate deeper learning, children should have consistent opportunities to develop both their critical thinking and creativity skills, as well as strengthening their social-emotional awareness. As a STEM campus, we will focus on engaging students and families with high-quality education in order to raise awareness of how the fields of Science, Technology, Engineering, and Math affect our everyday lives.

I am committed to partnering with you to provide our students with a caring, respectful, and safe learning environment at Southgate STEM.

I grew up in Del City, Oklahoma and graduated from Del City High School.  I attended Oklahoma State University where I graduated with a bachelor's degree in Elementary Education and then attended Lamar University where I received my master's degree in Technology Leadership and Administration.

When I'm not working, I love spending time with my family. I have a very supportive husband, Tim, and a high school-aged daughter, Olivia. We love to travel, play board games, and try new restaurants! 

I highly value parental engagement and believe your participation is vital. I look forward to working with you and your child as we learn and grow together.
