Katherine Sprissler-Klein

Senior consultant

Katherine Sprissler-Klein brings more than 15 years of fundraising experience at both large national organizations and beloved regional institutions. Her areas of expertise include individual major gifts, annual giving, corporate partnerships, cause marketing, special events and volunteer engagement.

Variety is the spice of life, and fundraising has created pathways for Katherine to make use of her skills while diving into causes she is passionate about. As a creative person with no tangible creative skills, she developed expertise in the arts and culture sector, including fundraising efforts for the $525M campaign for the Philadelphia Museum of Art and the Museum of the American Revolution. Katherine’s north star lies in equity for all, which brought her to Philabundance, the regional Feeding America affiliate, as the Deputy Director of Community Engagement where she led high-profile cause marketing campaigns, corporate partnerships, planned events and led community fundraising. 

A passionate ally, Katherine also worked in major gifts at the Human Rights Campaign, the nation’s largest LGBTQ+ advocacy organization. Constant checking of weather radar drew her to the American Red Cross National headquarters where she spent a formative five years managing large and multifaceted corporate partnerships, donor communications in times of crisis, high-impact stewardship opportunities and supported call-to-action campaign collateral creation. Committed to the rights of women and girls, Katherine began her career at the National Women’s Law Center, supporting special events, donor communications and recruitment.

Katherine resides in Philadelphia, PA with her husband, pre-school age daughter, and their rescue pup, Pixie.
