Meet Othelia Sierra, founder of The Math Mentors!

Graced with great teachers, Othelia loved learning math from an early age.

During high school, she challenged herself with enriched math courses and took 5 semesters of Spanish. Extracurricular activities like cheer, soccer, band, and choir made the years fun and memorable. After graduating high school, she considered a career in Astronomy and began studying in college.

In 2014, she completed an Associates degree in Physics from Harrisburg Area Community College, changed her major and went on to study at Millersville University.

Then, in 2016, Othelia earned a Bachelor of Science degree in Mathematics, with a Concentration in Actuarial Science. Soon after, she founded The Math Mentors LLC in June of 2017. 

Othelia's favorite subjects to tutor are Algebra, Geometry and SAT Prep.​​ Students appreciate her clear explanations, patience and passion for Mathematics.

When she isn't tutoring, Othelia enjoys helping facilitate youth programs at the local YMCA. Her son and she enjoy riding bike together and playing with legos. When she can, she continues to develop her stunting skills in acroyoga.

Gabriel Anthony-Kemp is a senior at Franklin & Marshall College pursuing a BA in American Studies and Business. He’s had a variety of experiences as an English tutor ranging from working as a literacy coach in Baltimore city public schools to being the Head Tutor at the F&M Writing Center. 

Gabe comes from a family of professors and educators, so it’s no surprise that whether he’s helping someone score highly on the SAT, craft their college essay, or write at the college level, he’s happy to assist! 

When he isn’t tutoring, Gabriel is a mentor for middle and high school students through two nonprofits in Lancaster. He loves to exercise, dining at local restaurants, and connect with new people.
