Our Staff
Hannah Fleetwood
MUSEUM MANAGER
Hannah Fleetwood often visited Yosemite during her childhood. She moved there for a seasonal position in 2018 and fell in love. She enjoyed working in Yosemite Valley for several years before moving just outside the park boundary. Hannah’s love for climbing was sparked at her first Facelift event in 2018. Since then, she has joined the YCA team full time at the museum. She is passionate about her community, cooking, and sharing her love for the outdoors. When she's not at the museum, you can find her splashing in alpine lakes or camping with her partner.
