John Marks is excited to bring nearly 20 years of Middle School Math experience to GPA. Throughout his career, he loved helping students find their potential by creating a classroom where students feel supported, encouraged, and confident as they take on challenges. Every student can grow and succeed with the right mindset: “I can do tough things!”

When he’s not teaching, he enjoys coaching baseball, spending time with his wife and nine-year-old twins, and being a part of the amazing community around him.
