George Feeny was Cory's sixth grade teacher (later retconned to being Cory's teacher from first grade and then retconned again into being his teacher from sixth grade) as well as the neighbor of the Matthews family.

As the series progresses, he starts working in the John Adams High School, just when the main characters begin to attend there. Eventually, he becomes the principal, and later on a college professor at Pennbrook. From the start of the series, Feeny attempts to be strictly a teacher to his students, but later develops close relationships with Cory, Shawn, Topanga and especially Eric. Feeny acts like more the authority figure than a mentor.
