This year, he is excited to join the math instruction team serving our upper school scholars teaching Pre-Algebra and Geometry. After graduating from high school, David moved to Coahuila, Mexico where he served as a volunteer for two years. During this time, he discovered a love for teaching and serving others. He developed a passion for helping others become the best version of themselves.

Upon returning from his two-year service, Mr. Monterroso began studying at Brigham Young University – Idaho where he focused his studies within mathematics and the physical sciences.

She is currently in charge of the PSO newsletter, Spirit shirts and is a room parent. She has been very involved in GHLO since our inaugural year, and couldn’t be happier to be a part of such a dynamic team. This is her third year teaching at GHLO.

She and her husband John, who is a ESS assistant teacher in lower school, have two scholars at GHLO. They are in second and eighth grade. In her free time she loves to play volleyball, read, craft and go camping.
