NEW YORK, NY (August 3, 2022) – Catholic Medical Mission Board (CMMB) named non-profit executive Heather Dennis as its new vice president of development.

Dennis joins the faith-based international health organization during its 110th anniversary year and brings more than two decades of strategic marketing and fundraising expertise to her new role. At CMMB, Dennis will lead the organization’s communications, fundraising and marketing initiatives.

“We are thrilled to have someone of Heather’s caliber join CMMB. She has a strong track record of cultivating new supporters, reducing fundraising costs and boosting donor revenue,” said Mary Beth Powers, president and CEO of CMMB. “Beyond her skill set, Heather brings a passion for serving the needs of women and children and making a positive difference in their lives.”

Most recently, Dennis served as the senior vice-president of Philanthropy and president at the Guideposts Foundation.

Prior to these roles, she worked in fundraising at American Red Cross in Greenwich, Conn., the New York State Historical Association, Iona College and Hartwick College.

“I am deeply impressed with CMMB’s global work and impact,” said Heather Dennis. “The organization provides critical medicines to underserved communities and strengthens life-saving health services for women and children. I look forward to working with the incredible team of staff, board members and partners to raise the funds needed to better the lives of these families.”

Dennis has a Bachelor of Arts degree in Business Management from Hartwick College in Oneonta, N.Y. She and her family, including two German shepherd rescue dogs, live in Greenwich, Conn.
