Amy Quilter - Executive Director, Board Member

After relocating with her family to Athens, GA, Amy took up tennis for the first time. In hopes of meeting a few people she started an introductory class for adults and she hasn't put her racket down since. She never imagined the rich community of players she would meet and how much joy she would find in playing! When she moved to Seattle three years later she was so smitten with the sport that she secured a spot on a team before she even landed in the city. She loves the personal challenges and goals, teamwork, and friendships that tennis has made possible.

Amy joined STEF to share her love of tennis with kids in hopes that what might start as just “something to do” will inspire friendships, fitness, teamwork, and a mindset to learn and grow on and off the court.Amy grew up in Upstate New York and attended Pharmacy school there. She and her family settled in Seattle about four years ago. She worked in retail and hospital settings as a pharmacist before deciding to be a stay at home mom 8 years ago. She loves Seattle and plans to live here with her husband and three boys for many years to come.


Roger Rogoff

Roger Rogoff - Member, STEF Advisory Board

Roger's passions in life have been kids, family and tennis. He is married with two daughters, ages seven and 15. As a kid, he played junior tennis in Tucson, eventually playing in college at Emory University in Atlanta. He taught tennis to adults and children in his late teens and early 20s.


One of Roger’s greatest regrets is taking a break from tennis when he began his legal career in the early 1990s. He prosecuted child sex crimes as a King County Deputy Prosecutor, spending significant time with underserved and at-risk youth. As an Assistant United States Attorney from 2006-2013, he prosecuted federal offenses, including Sexual Exploitation of Children. He is currently a judge in King County Superior Court, Juvenile Division.


Roger is a 4.5 player who competes in USTA leagues and tournaments.
