Lewis Flax

Lewis Flax helps nonprofits and corporations develop long-term, mutually beneficial partnerships.

Extensive Nonprofit and Corporate Experience

Lewis fully understands the challenges nonprofits face, both from an outside consultant’s point of view and from the internal perspective of a nonprofit executive. Lewis previously served as a Vice President for IEG, a sponsorship consulting firm, responsible for the Washington, D.C. metropolitan area nonprofit sector. He gained insight into both the nonprofit and 

corporate perspectives of numerous organizations. Lewis also led sponsorship efforts at Financial Executives International (FEI), a nonprofit professional membership association. He developed strategies for issues nonprofits routinely encounter—establishing partnership relationships as opposed to one-off transactions, packaging and valuing the offerings, and effectively addressing competing departmental interests. Through his efforts, FEI generated significant revenue gains. Lewis has walked in your shoes.

He founded Flax Associates in 2008.
