Meet Pat

With a deep passion for math and over a decade of experience in programming, Pat brings a unique blend of industry expertise and academic insight to his tutoring. After stepping away from his role as a Computer Scientist, he set out to give back to his community, helping the next generation thrive in a world where technology is evolving every day.

Pat believes that effective tutoring goes beyond improving grades or test scores. It’s about building confidence, nurturing curiosity, and empowering students to succeed — not just in school, but in life.

He has a BS in Math, a BS in Computer Science, and an MS in Computer Science from the University of Maryland Baltimore County (UMBC). Go Retrievers!

Why Abacus?

An abacus is one of the earliest tools created for solving mathematical problems. It is a simple, hand-operated calculator that only works with human touch and understanding. Unlike modern machines, it doesn’t do the math for you, it supports the person doing the thinking.

That’s the philosophy behind Abacus Tutoring.

We believe learning math and computer science shouldn't be about memorizing steps or programming kids to get the “right” answer. At Abacus, we help students think critically, solve problems creatively, and grow into independent learners — whether they’re tackling math basics or diving into computer science.
