Mary Olsen Obituary

Mary Anne Olsen, daughter of the late Maria Esteve and David W. Sheehan, was born on January 26, 1943, in New York City. She was one of six children-four boys and two girls-and grew up surrounded by a large and loving family.

A woman ahead of her time, Mary Anne was one of the original feminists-strong, independent, educated, and well-traveled. As a single mother during the transformative "Supermom" era, she balanced family and career with determination and grace.

Mary Anne devoted much of her professional life to service. She worked with the United States Agency for International Development (USAID), contributing to international development efforts that reflected her passion for helping others. Her work and adventurous spirit led her to live abroad in Barbados and the Dominican Republic, experiences she cherished deeply.

In addition to her international work, Mary Anne was a dedicated educator and served as an elementary school principal, shaping the lives of countless students with her leadership and compassion.

She was married for over 25 years to Jim Olsen. Together they raised two daughters, Kate whom preceded her in death.

Mary Anne is survived by her loving daughter Jackie and granddaughter "Charlie", three siblings, uncles several nieces and nephews, great-nieces and great-nephews, cousins and a host of extended family members and dear friends who will miss her strength, wisdom, and unwavering love.

Her life was a testament to independence, service, and devotion to family. She leaves behind a legacy of courage, compassion, and resilience that will live on in all who knew her.
