Heller Fundraising Group Team


Peter J Heller - principal

With over 27 years in the nonprofit world, Peter Heller has raised millions of dollars for many organizations while also strengthening their strategic and financial assets. His firm’s current consulting success is bolstered by the team of hands-on professionals he brings to the table, his extensive experience as a development staff member prior to launching his own firm, and his deep experience working on cultivating individual donors. He understands the client’s needs not only from the outside looking in, but vice versa.

Since 2004 Peter has been offering fundraising and strategic consulting services to a diverse group of nonprofit clients. He taught Major Gifts Fundraising in Columbia’s Fundraising Management Graduate Program, has trained fundraisers at The Foundation Center, is Co-Chair of Gotham Networking's "Make a Difference" group, and a member of the Nonprofit Resource Group.

For the 10 years before beginning his consulting business (1994-2004) Peter raised major support as a fundraiser and administrator for Columbia University, becoming the Director of Development for Columbia’s Engineering School. In securing support for University funding priorities, he worked closely with the Engineering School’s Dean and other University administrators raising significant dollars through his personal efforts and dramatically moving the School’s organizational strength forward. He also traveled extensively in the US and Asia to meet donors and raise funds.

Prior to his years at Columbia, Peter held development positions at several world-class universities during their campaigns including UC Berkeley, UC San Francisco (Associate Director of Corporate and Foundation Relations) and the American Friends of Tel Aviv University (Director of Corporations and Foundations). He started his career with a brief stint at his alma mater, College of the Atlantic (ME).

Peter attended Wesleyan University (CT) and College of the Atlantic, receiving a B.A. in Human Ecology from the latter in 1985. Before his nonprofit career, Peter ran his own vegetarian cooking and catering business in New York.

Peter is currently on the advisory board of the Inner Strength Foundation (PA) and has been providing pro-bono strategic advice to Earthdance (MA) for over 10 years.

betsy stewarD, Senior Consultant

Betsy is a seasoned fundraising professional who brings a variety of experience and enthusiasm to her role as senior consultant. As Director of Development for Westchester Children’s Association (WCA), Betsy led WCA’s five-year Centennial Campaign, raising $6.6M and exceeding the goal for this ambitious project, virtually doubling the organization’s operating budget. She oversaw all campaign major gift in-person solicitations, conducting face-to-face solicitations and securing gifts ranging from $1K to $1.5 million. Over the course of her decade at WCA, Betsy also oversaw the growth of WCA’s annual benefit, whose net earnings increased during her tenure by 730% (from $26K to $212K). She added more formal structure to WCA’s fundraising efforts, instituted more effective development procedures that contributed significantly to the growth of the organization, and established deep, long-term relationships with board members. Betsy believes that successful fundraising depends on a combination of relationship-building and story-telling, and she is especially proud of the “WCA Stories of Advocacy” that she developed for effectively explaining WCA’s child advocacy mission, methods and history to donors and prospective donors.

Betsy’s experience at WCA provided her with a strong knowledge of Westchester County and its philanthropic community. She was named the 2017 Fundraiser of the Year by the Hudson Valley Association of Development Officers. Before joining the team at WCA, Betsy served as president of the Foundation for Public Education in White Plains, where donations increased during her term by 89%.

A 2006 graduate of NYU’s Certificate in Fundraising program, Betsy’s first career was in music. Prior to her enrollment at NYU, she maintained a career in opera as soprano Elisabeth Van Ingen. She holds a master of music degree from Boston University and a bachelor of music degree from Lawrence University in Appleton, Wisconsin. She was awarded a Thomas J. Watson Fellowship, and has written for Chamber Music Magazine.

After retiring from opera, Betsy became proficient in software programs, eventually earning master certification in Microsoft Office. She founded and managed a successful software training service, training staff members at non-profit as well as for-profit organizations. Her expertise in computer programs has been an important asset to the critical organizational component of fundraising, and allows her to help our clients get the most out of the Heller Fundraising Group’s Free Tools.
