Marilu Vargas, Counselor

I began my school counseling journey in my native town of Los Angeles and made the leap to move to the great state of Texas in 2021! I am happy to be the school counselor at Hornsby Dunlap for a second year. I am fluent in both English and Spanish, my main goal is to close the achievement gap for Hornsby Elementary students by addressing their social and emotional needs. I am committed to creating a nurturing environment where every student can thrive and succeed. Beyond work, my hobbies include sewing, gardening, and traveling.
