Carol Gregory - Board Member, Treasurer

Carol Gregory didn’t grow up playing tennis.  Sure, she and her siblings hit a ball a time or two as kids, but it wasn’t an activity routinely in the mix.  


Carol’s coached sports; she’s captained USTA teams;  she’s lead PTA organizations; and, she’s done bake-sales.  She helps small and medium sized enterprises with outsourced finance functions when not helping raise two awesome daughters.   Carol brings to STEF a passion for not only inclusivity, but also an understanding that broadening a child’s view is akin to a pebble’s impact on still water.   


Carol graduated from Northern Illinois University with a B.S. in Accounting and earned her CPA (now, inactive).  While neither she nor her husband were born or raised in our region, they love the Pacific Northwest and strive through a variety of endeavors to make our community better.  She believes there’s no better place to begin than with our youth.

Geoff Harrison - Board Member, Secretary

Geoff started playing tennis when he was nine years old and grew to love the sport for its competition, all-around athleticism and most importantly, the fun of it. He has played competitively throughout his life and coached at the college level.


Geoff is a strong believer in early education success being a foundational skill for fulfillment in life. He has served on the board of New Discovery School, a play-based pre-school and coaches youth soccer and baseball teams.


Professionally, Geoff is a Partner and Chief Design Officer at Blink, a UX research and design firm.

Jim Vana - Board Member

Jim is a Partner at the Perkins Coie law firm, practicing in the intellectual property field. He received an undergraduate degree from the University of Michigan and a law degree from Indiana University.


Jim has been an enthusiastic supporter of tennis for many years with a focus on what the sport can do for youth. He previously volunteered with the Washington Tennis Foundation in Washington, DC.


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.

Wadiya Udell - Member, STEF Advisory Board

Wadiya is a developmental psychologist and faculty member at the University of Washington Bothell. She received an undergraduate degree from Wheaton College (MA) and a PhD from Columbia University. Wadiya has worked to promote developmentally appropriate and comprehensive approaches to health promotion and risk prevention among youth.


“Community-based programs offer great opportunities to enhance the factors that promote healthy development among youth and children," she says. "STEF offers youth in underserved Seattle communities opportunities to foster their physical, educational, and socio-emotional health in a fun and engaging setting.”
