DAN PRIZER’s fundraising career began while still an undergraduate at Columbia University in the early 1980s, where he helped pay his way through college with a job in the Office of University Development and Alumni Relations, learning the basics of corporate, foundation and individual research in the University’s vast library system while profiling alumni and other candidates for Columbia’s billion dollar capital campaign.

After graduation, Dan served as Director of Prospect Research at New York City’s St. Luke’s-Roosevelt Hospital Center (now Mount Sinai St. Luke’s and Mount Sinai Roosevelt Hospitals), where he was in charge of identifying donor prospects for a $40 million capital campaign; creating the framework and preparatory materials for a campaign feasibility study by Brakeley, John Price Jones Inc.; identifying candidates for the Hospital’s Board of Trustees; developing databases to track prospects; and overseeing the purchase and maintenance of all computer hardware and software programs for the Hospital’s annual mailings, events and receipting of gifts.

Dan was promoted to Director of Major Gifts at St. Luke’s-Roosevelt where his primary responsibility included soliciting many of the prospects he had identified as a researcher. In this capacity he worked with Trustees and volunteers to secure major gifts for the Campaign for St. Luke’s-Roosevelt. Dan has been with Keelyn Mulvey & Associates since 1985 and works in various capacities with many clients, including not just private grant proposals, but large government contracts, and reporting and stewardship post-funding.
