On April 7, 2026, the Nashua, New Hampshire community mourned the loss of Callie Klimas, a beloved daughter, sister, friend, and pillar of strength whose legacy of kindness, compassion, and unwavering support touched the lives of many. Callie passed away peacefully at the age of 48, surrounded by family and close friends after a brave battle with illness.
Born on May 12, 1977, in Nashua, Callie was the cherished daughter of the late James and Patricia Klimas. Her early years were marked by a natural curiosity and deep empathy for others. Growing up in southern New Hampshire, she attended Nashua public schools, where teachers and classmates remember her as a bright, thoughtful student who always lent a helping hand. Her commitment to community service began at a young age and continued throughout her life.
Callie graduated from Nashua High School in 1995 and went on to earn her Bachelor’s degree in Social Work from the University of New Hampshire. Her passion for helping others led her to a lifelong career in social services, where she advocated for vulnerable populations and worked tirelessly to improve access to care, education, and mental health resources. Colleagues and clients alike admired her dedication, warm spirit, and steadfast integrity.
Throughout her career, Callie served in various leadership roles with local nonprofit organizations in Nashua and the greater New England area. She was especially recognized for her work supporting families affected by addiction, trauma, and economic hardship. Her innovative programs helped countless individuals regain stability and hope. In 2019, she received the Community Advocate Award from the Nashua Human Services Coalition for her invaluable contributions.
Callie was more than her professional legacy — she was a beloved member of her community. She volunteered weekly at local shelters, organized neighborhood drives for food and clothing donations, and never hesitated to offer support to those in need. Her tireless efforts created meaningful change and fostered a sense of unity among neighbors, friends, and acquaintances.
Family was Callie’s greatest joy. She is survived by her sister, Alexandra Klimas of Manchester, NH, her nephew Lucas, her partner of 15 years, Michael Donovan of Nashua, and an extended family of aunts, uncles, and cousins who will deeply miss her presence, laughter, and unwavering love. Her warmth was a constant source of comfort, especially during life’s most challenging moments.
Friends remember Callie as a vibrant spirit who loved the arts, nature walks along Nashua River, and Sundays spent with people she cherished most. She found peace in quiet mornings with a cup of coffee, and joy in spontaneous road trips with loved ones. Her genuine curiosity about life and people made every interaction memorable and every connection meaningful.
A memorial service celebrating Callie’s life will be held on Saturday, April 17, 2026, at 11:00 AM at St. Christopher’s Episcopal Church in Nashua, NH. Family and friends are invited to share stories, memories, and honor her legacy of compassion, love, and community service. In lieu of flowers, the family requests donations to the Nashua Community Outreach Center, an organization close to Callie’s heart.
Callie Klimas’s impact on Nashua, New Hampshire, and beyond will be remembered for generations. Her life was a testament to the power of empathy, resilience, and love — a legacy that will continue to inspire all who knew her.
