Jhino Medrano, Extracurricular Coordinator
Jhino hails from Houston, TX.

He joined AIS in 2014 as an After-School Care Counselor, and the following school year, he was named the Extracurricular Activity Coordinator. He is excited to work in this new role as it brings him joy to see children learn and progress together, regardless of age. His goal is to enhance the after-school program by making it a fun learning experience for the children. Jhino was a competitive tennis player in high school and volunteered at the school’s library. When not at work, he loves to explore the outdoors and try different types of cuisine from food trucks and restaurants. Jhino holds a certificate for Medical Assisting from the Everest Institute in Austin.
