Nelius Gathondu, B.S.
My experience as a first generation, non-native student in college, allowed me to understand the pressures and challenges that students have to perform well in school. Be it low self-confidence stemming from a bad test grade, to the inherent fear at the thought of tackling Calculus. I went through it all. I have found that the teachers who were able to tap into my potential were those that were encouraging and allowed me to voice my ‘stupid’ questions, but at the same time have great expectations of me. I employ this same style of teaching, identifying individual student needs, and building a line of communication of respect and trust.
I earned my Bachelors of Science degree in Biochemistry and Molecular Biology from Mills College in 2013. Including teaching and tutoring experiences at Mills in subjects like Physiology and Chemistry, I participated in a multi-campus research study trying to answer why female students feel discouraged to go into the sciences. At Tilden, I hope to inspire and share with students the same enjoyment of science and math I have grown to have.

I’ve always have had an immense passion for life as well as a unquenchable curiosity for learning. Art, science, languages, culture, movies, astronomy, philosophy and even gardening are among the many interests that have inspired me growing up.

I picked up the language rapidly and that experience landed me in college in the American Sign Language Interpreting program at the National Technical Institute for the Deaf in Rochester, New York. Upon graduation, I worked as an interpreter at a local Wisconsin college. I’ve always had the idea of moving to the West coast and when my brother and sister made the move to California, that was the push I needed. In July of 2014, I packed my bags and moved to beautiful California in hopes of wonderful and enriching experiences. I enjoy sight seeing, checking out local museums, trying out restaurants and spending time with friends. My philosophy is you must always live your life to the fullest and that anything you want, believe in yourself and you can make it happen!.

Born and raised in San Bruno on the peninsula, Eleodoro ("Lolo") attended UC San Diego, earning a B.A. in Ethnic Studies and Sociology. His love for the Bay Area called him back, and he worked for a non-profit in San Francisco within the resident services department for a housing provider for a number of years before earning his M.A. in Education with an emphasis on Equity and Social Justice from San Francisco State. Lolo strongly believes in tailoring each of his classes to his student’s interests and background, and incorporating these elements into his curriculum. Although Lolo loves teaching a number of subjects within the humanities, he has a particular love and affinity for history and its interdisciplinary aspects and complexities. He also believes in drawing upon and celebrating his students’ own funds of knowledge and incorporating these elements every day. Lolo enjoys running, hiking, the 49ers, pop culture, NPR and bird watching.
