Board of Directors

Trisha Roberson

Trisha currently serves as the President of the VUL on the Board of Directors. She joined the board in 2016 and has served as the chair of the Strategic Planning Committee, as well as on the Finance Committee, Hall of Fame Committee, and Code of Conduct Committee.

In 2017 she helped found the mixed touring teams Fable and Mastadon with the goal of creating a sustained, competitive mixed program in Vancouver. She captained Fable from 2017-2019. With female-matching and male-matching players on the field, mixed ultimate is an important arena for promoting gender equity and Spirit of the Game. In 2018, Trisha along with other Fable leadership helped form a second mixed team, Mola Mola. In 2019, Trisha helped foster the growth of beach ultimate community in Vancouver, hosting the twice-weekly Famous Vancouver Beach Ultimate Pickup Game.

Trisha works as an operations manager at the Nikkei National Museum and Cultural Centre and holds a BSc in Physics and Philosophy, a MSc in Geophysics, and a PMP designation. When not training for, researching, watching, or playing ultimate, Trisha can be found reading, hiking, cycling, or thinking about science, feminism, social justice, and how to save the planet.

Sarah Cawston-Stewart

Sarah got her first taste of ultimate in high school in 2003. She played the VUL for the first time that summer and has never looked back. She absolutely loves the camaraderie, and friendships she’s made from playing Frisbee. This sport, through its commitment to spirit of the game, really takes sportsmanship combined with talent to the next level. Also the heckling; she loves the heckling. She’s had the pleasure to play mixed summer, mixed winter, mixed winter hat, fall grass, winter Parity, and mentor women’s fall turf, along with more tournaments (recreational, touring, mixed and women’s) than she can count. She played 2 years in England on an English Mixed team that went to World’s 2010 in Prague. Meanwhile, back in Canada Sarah has played with Zephyr and Wendigo women’s club, and most recently with Fable mixed ultimate club. When Sarah isn’t playing Frisbee, she loudly tinkers away at making music in her home studio. She earns a living as a self-employed contractor teaching piano and trumpet to students of all ages. Sarah previously served as Secretary and is now the board's Vice President.

Ken Su

Ken is privileged and grateful to be able to serve on the board of the VULS. Since having the good fortune of being introduced to ultimate in high school via outreach efforts of the BCDSS, he has loved the game and truly appreciated the Vancouver disc sports community. He strives every day to live by the principles behind the name 'ultimate,' the Spirit of the Game, and the many unique aspects of our sport. He started playing ultimate in the VUL in 1992 and has been lucky enough to have the chance to play with a number of teams and meeting so many amazing ultimate people over the years. Ken was away from Vancouver between 2004 and 2016 in China where he was involved with introducing ultimate to new people across China and the ongoing early stage development of the ultimate community and ultimate organizations in China. Since returning to Vancouver, Ken has enjoyed getting back on the field with old friends and teammates and meeting new players and teams. He is honored to have been re-elected to the board and will work hard for the members and support the VULS any way he can.

Outside of Ultimate, Ken spends time working with clients on their mergers and acquisitions and cross-border investments, as well as being a dad to his energetic young son.

He's played in seven consecutive summer leagues and since discovering that turf leagues play year-round he hasn't missed a season. After making many great friends over the years, David is hoping to use this board position to give back to the community which has provided him with so much fun and happiness.

Christa has the pleasure of captaining the Technicolour Narwhal Explosion and is convinced they have the best uniforms in the league. She is delighted to join the board and is excited to support the league in continuing to be a world leader in ultimate.

Lisa Riddle

Lisa started playing ultimate with friends in 1998 in Toronto. She joined her first team in 1999 in Vancouver and played competitively for a couple years with Idle Hands and the Roughriders, among others, before having her daughter. Her passion for ultimate has never waned and, as a result, she recently started teaching ultimate to the kids at her daughter's school in North Vancouver.

Ultimate has so much to offer young people that is not being provided in other sports, in the spirit of the game and in the development of mediation skills when conflict arises. It also allows for those skills to be developed while playing with people of different genders. And, it's just so much more fun than other sports!

Lisa works as a lawyer at the Department of Justice and is a passionate advocate for equality. Outside of ultimate, Lisa and her daughter spend all their spare time riding horses.
