Rosie Sullivan - Bookkeeper

Boulder, CO

Rosie's first experience with cohousing was in 2012 when she moved from her home state of Minnesota to Nyland Cohousing in Lafayette, Colorado. Knowing very few people in her new state, Rosie was able to find immediate comfort and support in the community. She eventually moved to Boulder to be closer to her job, as office manager at Wonderland Hill Development Company. Attending every national conference since her introduction to cohousing in 2012, Rosie is excited to offer her bookkeeping skills to support Coho/US and its mission.
