Originally from Boston, Massachusetts, Siobhan has called Melbourne home for the last ten years.

Siobhan grew up in a lacrosse family and continued to play while attending the University of Alabama, before hanging up her boots in 2014. During the COVID-19 pandemic, she joined the new Brunswick Lacrosse women's team on a whim. Through watching a team of new lacrosse players celebrate the small wins and develop year on year, she fell back in love with the sport. Passionate about community-level participation, particularly for girls and women, Siobhan is now one of the head coaches for Brunswick's senior women's team.

Off the lacrosse field, Siobhan is an international development practitioner currently working on a women's leadership program in the Pacific. With a professional background in women's health, leadership development, and strategic communications, Siobhan brings that knowledge and expertise to the board of Lacrosse Victoria.
