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.

Michael Mendoza, B.A.
I was born and raised in Milwaukee, Wisconsin. Growing up in the Midwest, I had a peaceful and laid back upbringing. 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. My last year in high school, I met a fellow student who was deaf and I took it upon myself to learn sign language so we could have a friendship. 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!.
