Sometimes the best experience is gained by giving back to others. Catchafire.org gives people on both sides of the volunteer equation the ability to make it easier to give back and gain experience at the same time.
From their website:
Catchafire is a website that makes it easy for professionals to volunteer their on-the-job skills for nonprofits and social enterprises that need their help in areas such as marketing, PR, design, social media, strategy, and finance on a pro bono basis. You can think of us as an eHarmony for skilled volunteers and social mission organizations.
First and foremost, we match you with an organization that has made a strong commitment to work with you on a Catchafire Project. We also connect you with an organization whose cause(s) you care about and whose mission you support. We currently only serve organizations that have a presence in NYC, though many have other offices across the country and around the world. We connect our volunteers to both nonprofits and social enterprises who represent a wide range of diverse causes.
