Representatives from Greater Cleveland nonprofits are invited to hear Perla Ni, founder and CEO of GreatNonprofits, speak about marketing organizations in tough economic times at the closing lunch of the Ohio Grantmakers Forum’s annual conference in Cleveland October 29.

GreatNonprofits is a website that collects and shares user reviews of nonprofits to help donors and volunteers learn more about small, less visible nonprofit organizations. Ni also is founder and former publisher of the Stanford Social Innovation Review.

Registration for the program at the Cleveland Marriott at Key Center is $40.
