Driving Corporate Social Impact: A Conversation with New GPCVN Co-Chairs Christine Jereb and Haley Velletri

The Greater Philadelphia Corporate Volunteer Network (GPCVN), a Chamber-hosted network, brings together leaders in Corporate Social Responsibility (CSR) to share best practices and collectively strengthen the region through employee engagement. It is a hub for thought leadership, learning, and collaboration. The network helps corporate leaders stay ahead of emerging trends and align their CSR efforts with the needs of their community and our region.

We got to know its new co-chairs, Christine Jereb, Executive Director of Impact & Inclusion, Comcast, and Haley Velletri, Project Manager, Engagement & Inclusion, Vanguard, as they shared their vision for the GPCVN and why CSR is key to inclusive business growth.

Christine and Haley are both proud to call Greater Philadelphia home, and their career paths prove just how invested they are in the region.

Christine leads Team UP at Comcast, its year-round employee volunteerism and engagement program. In her role as Executive Director, Impact & Inclusion, her and her team connect Comcast employees with opportunities to get involved in the community both in Philadelphia and across the country.

“I’ve been fortunate to carve out a career path that leverages my skills, gives me an outlet to connect others to purpose, and drive positive impact in the community.”

Haley serves in strategic roles at Vanguard, focusing on Community Stewardship by facilitating employee engagement in community initiatives and promoting awareness of local support opportunities, including spearheading the development of Vanguard’s first enterprise-wide dashboards for community engagement and playing a key role in launching both the employee relief fund and volunteer rewards program. Currently, she works with Vanguard’s Diversity, Equity, and Inclusion team to enhance engagement and inclusion strategies through comprehensive employee listening, research, and ongoing analysis.

“My commitment to Philadelphia remains strong, and I continually seek meaningful ways to contribute positively to the city.”

As professionals dedicated to growing inclusive spaces in the workplace and beyond, being a part of GPCVN has had an enormous influence on both their growth and leadership.

Christine routinely leans on GPCVN to help her enhance and advance CSR within her own company. “The group helps me stay on top of emerging trends and best practices in addition to understanding the key community priorities in the city and region. I can then bring those insights back to my company as we develop and enhance our programs. The connections formed through GPCVN also make it easier to collaborate with other companies. I know I have trusted advisors that I can tap at any time through GPCVN.”

For Haley, the connections cultivated through GPCVN are unmatched.

“I deeply appreciate the collaborative ethos that defines this community—a network where practitioners unite around shared ambitions, navigate distinct challenges, and pioneer inventive approaches shaped by Philadelphia’s vibrant landscape. The GPCVN’s regional focus offers insights and alliances that simply can’t be found elsewhere; it is this sense of local connectedness and collective momentum that continually inspires me and broadens my understanding of what it means to be an engaged corporate citizen.”

Both leaders strongly believes CSR is not just a corporate obligation but a business imperative.

Haley firmly believes “the growth and prosperity of businesses are closely linked to the well-being of their surrounding communities. Effective corporate social responsibility (CSR) initiatives foster trust, strengthen relationships, and create new opportunities. CSR enables businesses to remain attentive to evolving customer and community needs, while communities benefit from additional resources and enhanced collaboration.”

Christine echoes this sentiment that, “businesses can’t thrive unless their communities are healthy When done right, CSR builds trust, strengthens connections, and opens doors. It helps businesses stay in front of customers and community needs, and for communities, it can bring in new resources and deepen relationships.”

As they dive into their new roles as co-chairs, Christine and Haley are not just hoping but actively preparing to bring growth to GPCVN as the group enters a new era.

“We hope that we can continue to engage our long-term members with deep conversations on evolving conversations in the space, as well as create space for new members to get involved – those that are building a social impact program for the first time or navigating any portion of this work as an aside to their main roles at their companies,” said Haley. She has also expressed the desire to create more opportunities to build mentorship into the network.

For Christine, it’s about shaping GPCVN programs to be a space that “brings in perspectives from our member companies as well as community leaders and allows for our members to have open dialogue to connect with each other and tackle whatever challenges they may be facing with their programs.”

Though under new guidance, our new co-chairs are confident that our region’s “business entities understand the importance of being locally involved and invested,” and that GPCVN “will continue to be a mechanism for businesses [both seasoned and new] to come together to share best practices to positively impact communities.”
