Meet the Mentors!

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.

Todd Wisotzkey has been a math fan ever since he was old enough to count. A native of York County, Todd completed his BA in Mathematics at Western Maryland College (now named McDaniel College). During his undergraduate years, Todd developed an interest in applied Mathematics, especially in the areas of Economics and Operations Research.

Since college, Todd has built a career in the business world with a focus on the areas of demand analytics, forecasting and the global supply chain. He has worked in finance, manufacturing, and distribution businesses, and is currently a Product Manager in the Telecommunications industry.

Todd is the father of 5 children, all of whom have successfully completed their high school educations. He looks forward to meeting and tutoring math students of all levels and is well prepared to answer the difficult “why do I have to learn THIS?” question!

If he’s not behind his computer or working through Math Olympiad problems he found on YouTube, you might find Todd jogging for exercise, reading fiction mystery novels, or daydreaming about the beach.

Mahadeva Swamy graduated in Mathematics in 2009, from the University of Mysore, then received his Bachelor of Education degree a year later at the same school.

Soon after he started teaching math. He was very curious about math from an early age and now was turning it into a passion.

In 2016, Mahadeva completed his Masters of Science in Mathematics at Kuvempu University.

His favorite subjects to tutor are pre-calculus, calculus, pre-algebra, algebra, geometry, SAT and GRE prep. He joined The Math Mentors last year and started to tutor lessons online. He enjoys working with his students and being part of The Math Mentors team.
