Formally trained as a writer and artist, Lynne is now an activist for the arts and for pressing social issues. Her core values are derived from her family and her Jewish heritage—a legacy that values family, hard work and civic responsibility. In 1976, she established Regional Media Associates, an in-house advertising agency for the Honickman Bottling Group, where she served as president and creative director for fifteen years. As her children, her own life and her husband's career matured, Lynne expanded her love for the arts into a commitment to social causes that support and benefit many of the artists, friends and acquaintances who had touched and influenced her life. She had learned from a family tradition of 'Tikkun Haalam'—to repair the world—believing with Martin Luther King that “our lives begin and end the day we become silent about things that really matter.” In the mid-eighties, Lynne joined the fledgling God's Love We Deliver, a feeding and educational service in New York for the homebound living with AIDS, and served as trustee of GLWD for twelve years.

Currently, she is a trustee of the Philadelphia Museum of Art, serving as chairman of the Education Committee; a member of the Prints, Drawing and Photography Committee as well as the Architectural Review Committee, and a member of the Friends of the Alfred Stieglitz Center. She is also on the board of Project H.O.M.E., which provides housing, opportunities, medical care and education for the homeless and at risk individuals and families. Lynne serves on the Mayor's Council for the Homeless, the Mayor's Task Force to End Homelessness Action Leadership Team, and the advisory board of MANNA (Metropolitan Area Neighborhood Nutrition Alliance).
