Ms. Raegan Costabile

I was born and raised in West Texas. I began my educational career by teaching and coaching at Cuero Junior High in Cuero, TX. I then went on to Granbury, TX, where I taught 4th Grade at Acton Elementary. I came back to San Marcos in 2020 to teach 5th Grade at Rodriguez Elementary. I arrived at Goodnight to serve as Assistant Principal in 2023. I love being able to call San Marcos “home” and appreciate all that this wonderful community entails. My hobbies include exercising at Camp Gladiator, running, trying new places to eat, and hanging out with family and friends. Above all, I love collaboration and working with our families to ensure our students are succeeding in every which way. Teamwork makes the dream work! Please reach out if I can ever be of assistance!
