Withum in the Philadelphia Community
Philly is home to a vibrant, passionate and gritty local community, and our team members who live and work here mirror that spirit. Withum’s Philadelphia team is proud to support the many charitable, community-based and not-for-profit organizations that uplift this city, its people and its communities. We host the annual Big 5 Game Watch networking event supporting the Philadelphia Ronald McDonald House and American Cancer Society. Our team also takes part in volunteer opportunities at nonprofits like MANNA, Philabundance, Bethesda Project and more. Community is a core pillar of the Withum way, and we sponsor yearly galas, golf outings and events with organizations like Community Options, Inc., Jewish Community Housing Corporation, Woods Services, SpArc Philadelphia and many others. Philly’s Women of Withum chapter also participates in “adopt-a-family” initiatives with local organizations to help brighten up families’ holidays.
