Welcome to Algebrility!

Coach Dexter founded Algebrility out of an abundance of enjoyment for teaching mathematics to students of all ages and learning differences. A career that began with volunteering as a tutor in the District of Columbia has soared into disseminating knowledge to students full-time throughout the entire Washington Metropolitan Area and globally. He has over 10,000 hours of experience delivering individualized learning that students can't always get in a classroom setting.

Since 2013, scores of students have improved their understanding of mathematics, leading to much higher achievement and confidence in school. In addition to all high school courses—from Pre-Algebra to Advanced Placement (AP) & International Baccalaureate (IB)—Dexter provides remote 1-on-1 private tutoring for all parts of the SAT, ACT and the high school entrance exam, the SSAT.

A native Washingtonian, Dexter completed the IB programme at Benjamin Banneker Academic High School and graduated from Dartmouth College with a degree in mathematics and economics. In his free time, Dexter loves to play tennis, watch live sports, and read presidential history novels.

Note: All students receive unique, password-secured Zoom meeting access.

Dexter has helped my son achieve better grades in his IB standard level maths and this has lead to an all round improvement in his grades for his other IB subjects as his confidence has improved. He is patient and methodical and shows my son exactly what he needs to do to gain the most points when answering questions."
