Armstrong Tutoring has experienced certified teachers as their tutors. These professionals were chosen due to their extensive knowledge of the curriculum, outstanding ability to reach students in a variety of ways, and their engaging personalities. Their services include subject area tutoring for all courses including AP, test prep for PSAT, SAT & ACT, and study skills lessons. History Established in 2009. Armstrong Tutoring was started in 2009 by Ellen Armstrong, who as a former teacher and then fully booked private tutor, decided to find another great tutor who could help the students on her waiting list. As the excellent reputation continued to spread, Armstrong hired more and more tutors, leading to an extremely successful education center who has helped thousands of students over the years.
