Lariel Mateo, M.S.

Founder + Educator

About Lariel

Lariel started Mateo Tutoring in July of 2020 and has served as founder, educator, and educational consultant since then.

Lariel holds a Master of Science in Applied Exercise Science and a Bachelor’s in Health and Exercise Science. Exercise physiology was the basis for her academy curiosity, but soon became her avenue for research, curriculum development, and teaching. Before starting Mateo Tutoring, she represented other well-established educational organizations that serve the Stockton community, such as former private tutoring business Muskal Assessment & Learning Clinic, Inc; the Career Resource Center and General Academic Tutoring Center at the University of the Pacific; the AVID program within the Stockton Unified School District; and charter school Venture Academy Family of Schools.

Lariel’s teaching philosophy is embodied by the idea that effective educators teach students how to learn. She takes much interest in cognitive science and how it applies to learning and one-on-one instruction. She believes that strategies that are both based in research and specific to each student are able to transcend subject areas and time. The opportunity to influence students’ trajectory has been a hallmark of Lariel’s life.

When Lariel is not teaching, she loves going on trail and beach runs with her Australian Shepherd Top. She taps into her create side through her anatomy art brand Made For Everybody. As a player for United States korfball and the Portuguese club Quinta dos Lombos, a coach, and representative of the United States Korfball Federation and International Korfball Federation, she is a proponent of the mixed gender team sport korfball.

She and the Mateo Tutoring team hope to inspire students’ confidence in themselves and their capacity to make a unique impression on this world.

Leo Libres

College Admissions Counselor

About Leo

Leo joined the Mateo Tutoring team in March of 2025. From searching for, applying to, and selecting colleges to pursuing a trade to exploring alternative routes, such as taking a gap year or entering the workforce, Leo uses his 15+ years of experience to guide high school students and their families through the post-secondary school process.

In addition to serving as our college admissions counselor, Leo is a college counselor in a professional, academic setting and is en route to completing the College Counseling Program at University of California, Los Angeles. Prior to his current roles, he has worked in higher education for over 14 years, holding various positions within student services. His professional experience has provided insight into diverse areas of academia, forged connections with professors, deans, and other key stakeholders in education, and allowed him to reach students of all levels: high school, undergraduate, and graduate students. He earned a Bachelor of Science in Criminal Justice & Organizational Leadership and an Associate of Applied Science in Business Software Applications. As a first-generation college student growing up in a single parent household in Stockton, California and not having any post-secondary guidance, it is Leo’s goal to share the institutional knowledge he has gained over the years.

When he is away from the professional setting, he spends a large amount of time golfing. He is super obsessed with it. It is a sport that is brutal and unforgiving and that challenges players mentally due to its small margin for error (sort of like life). The sport humbles even the most high and mighty and because he will never conquer it, he finds it thrilling to try. He does carve out a good amount of time to binge watch movies or television series with his wife. They visit local hiking trails and out of town golf courses and attend professional sporting events thanks to his daughter who gives them free tickets to see the A’s, Giants, Rivercarts, Ports, and Kings. Most importantly, he spends quality time with their fur baby.
