Joanna Linkchorst is a lifelong Crescenta Valley resident and a self-proclaimed “history dork”. She is the founder and President of the Friends of Rockhaven. When her children were younger, she gleefully involved herself in their classrooms, historical re-enactment days, served on the PTA board and was president of the elementary school’s foundation. When her kids grew older, she became a volunteer docent at the Autry Museum of the American West. She has used this training to be an enthusiastic tour guide at the Rockhaven property, as well as speaker at various groups and historical societies.
