Current Board Members
Sonya started playing Ultimate in 1998. After moving to Madison, WI from her native Canada she met some ultimate players who needed women for their team and were willing to train a soccer player. The spirit of the game won her over. She moved to Boulder and started playing GRU league in 1999. From 2005 to 2011 she was responsible for ordering GRU league shirts, discs and prizes as well as managing the league feedback surveys. Sonya joined the board in 2009 and took on the role of President in 2010.

Carley had her first taste of Ultimate as a Media Intern for USA Ultimate in the spring of 2010, but it was not until that fall she touched a disk and was welcomed into the GRU community with open arms.
