RUF is proud to introduce our experienced coaches



After being a life long soccer player, Georgie found a new passion playing ultimate their first year at Philadelphia University. They played on the mix team of their first semester before being part of the inaugural women's program in the spring of 2012. In their second year as a team, PhilaU made D3 Nationals, and as one of the primary handlers, Georgie played a significant role in helping the team place fifth. Georgie finished out their college career at PhilaU, including two years of captaining, before a series of unfortunate injuries kept them from playing competitive ultimate for a few years. It was during this time that they found a love of teaching the game of ultimate. In 2019, Georgie finally return to playing competitive ultimate where they played on Broad City. In 2021, they captained the inaugural season of Philadelphia Flock (now Zephyr), before moving up in the Philadelphia women's club program (the Flock) to play on Philadelphia Fight in 2022. While playing for the Flock, Georgie wanted to give back to the ultimate community, and ensure they would never be away from the sport they loved, so they decided to start coaching. In spring of 2023, Georgie took over as head coach of Radnor Girls Ultimate.


This is Zane's second year as an Ultimate coach. Zane started as an assistant coach for ColorBomb - an adult Mixed Division Club team focused on equity and dedicated to empowering players with diverse identities and was also the assistant coach for the U20 YCC Mixed team (Philadelphia Forge) that traveled to Nationals. This is Zane's ninth year playing Ultimate, having started at Haverford High School and continuing through college and club. Zane looks forward to bringing the best out of everyone, sharing my experience with the team, and having fun with everyone.
