Historic Bethlehem Museums & Sites, the Bethlehem-based nonprofit focused on historic preservation, education and community enrichment, has named Colleen Gilbert chair of its board of trustees. Gilbert, a Bethlehem resident, assumed the role Jan. 1.

A retired marketing professional with 25 years of experience in financial services, destination marketing and higher education, Gilbert has worked with Wells Fargo; the cities of Branson, Missouri, and Pigeon Forge, Tennessee; and The Ohio State University. She also serves as co-chair of the Tocqueville Society for United Way and volunteers with the Early Childhood Education Collaborative.

A Lehigh Valley resident for the past nine years, Gilbert previously lived in Belgium and the United Arab Emirates. During that time, she was involved with the Federation of American Women’s Clubs Overseas, helping liberate victims of human trafficking, and served as a delegate to the United Nations Council on Women. She and her husband, Mark, frequently travel to visit their three adult children.

Other officers of the board for 2026 are Vice Chair David Thomson of Bethlehem, Secretary Sheela Donchez of Bethlehem and Treasurer Larry Eighmy, founder and managing principal of The Stone House Group.

“Historic Bethlehem Museums & Sites is excited to welcome Colleen Gilbert as chair of the board of trustees,” said LoriAnn Wukitsch, president and CEO. “Colleen brings more than a quarter-century of experience in destination and nonprofit marketing, and her expertise and leadership have already benefited the organization through her role as both a board member and chair of our marketing committee. We look forward to her continued leadership as we expand our historic preservation efforts, draw more visitors to Bethlehem, and complete the Taking the World Stage capital campaign and the Overlook on History in 2026.”

Wukitsch also thanked outgoing board chair Joel Rosenfeld for six years of leadership.

“His tenure spanned an unprecedented period, from the COVID-19 pandemic through the recovery and the inscription of the UNESCO World Heritage Site,” she said. “His steady guidance shaped each step of that journey, and his leadership will have a lasting impact.”

Historic Bethlehem also welcomed four new members to its board of trustees. Rocco Beltrami, Ray Glemser, Dayna Plocus and Kristina Warner will serve three-year terms on the 36-member board, which oversees the governance and strategic direction of the organization.

Beltrami is an associate at Norris McLaughlin, focusing on municipal law, real estate, land use and zoning matters. He earned a bachelor’s degree from Moravian University and a law degree from Villanova University’s Charles Widger School of Law. He chairs the Northampton County Bar Association’s Municipal Law Committee and has been named to the Best Lawyers: Ones to Watch in America list for corporate law and litigation the past two years.

Glemser is chair and chief executive officer of Glemser Technologies Corp., which provides technology-enabled solutions and services for life sciences companies. He graduated summa cum laude from Lehigh University with a bachelor’s degree in computing and information sciences in 1983, earned a master’s degree in industrial engineering in 1984 and a doctorate in philosophy in 1991, both from Lehigh. He has served on several regional boards, including Think Hope Foundation, Snyder Technologies LLC, Regina Academy at St. John the Baptist in Ottsville, and the Industrial and Systems Engineering Advisory Council.

Plocus has 20 years of experience in marketing, public relations and real estate. She began her career as director of marketing for Christofle of Paris before becoming a licensed Realtor and professional home stager. In addition to serving on the board, she chairs the organization’s Rooms to View House & Garden Tour planning committee and volunteers with several other Lehigh Valley nonprofits. She earned a bachelor’s degree in finance from Lehigh University and lives in Bethlehem with her husband, Bronson.

She has served on several local boards, including the Junior League of the Lehigh Valley, the Auxiliary of St. Luke’s University Health Network, the St. Luke’s University Health Network board of trustees, Penn State LaunchBox Ladies and the Monocacy Farm Project.
