Having first encountered Ultimate Impact programming in the 4th grade, Coach Paolo loves to be on the other side now as a coach, seeing how youth grow over time in our programs. His favorite part? “Seeing the ‘Aha!’ moments where they learn or understand something new about ultimate frisbee, whether it’s them catching a frisbee one handed for the first time or being able to get to 10 catches in a row.” Paolo graduated from Burton High School in 2025. Outside of school and work, Paolo is a huge baseball fan (go Giants!) and loves to stay active.
