Today, we gather not just in mourning, but in deep gratitude for the life of L. Thomas Mangrum, Jr., a man whose presence made a difference, whose work left a legacy, and whose spirit touched everyone privileged to know him.

We at Quality Trust are proud to have known and worked with Thomas. Thomas oriented our new Board members when they started their term, served on the collaboration committee of our #ProjectPeerToo project, and trained lawyers, disability professionals, and others with our staff attorneys. Thomas co-facilitated training sessions with our former Board Chair for law students at American University’s Washington College of Law.

He advised us on issues he observed in the community and how he thought we could make a difference, including accessible transportation and sidewalks, ensuring that staff respected and supported people how they wanted them to and other injustices he witnessed. Thomas would promptly respond when we called to testify at City Council or on Capitol Hill. He travelled locally and nationally, presenting and amplifying the voice of people with disabilities. You would often hear him say, “Nothing About Us, Without Us.”

Thomas’ advocacy work has been defined by unwavering integrity, deep compassion, and an unrelenting commitment to justice and inclusion. He brought not only his lived experience, but also his heart – ensuring that people with intellectual and developmental disabilities were not just protected but empowered. His efforts lay the foundation for more equitable systems, more responsive services, and a culture that listens, supports, and advocates.

But beyond his advocacy and professional accomplishments – which were too many to acknowledge – Thomas was simply a good man, accepting,

kind, with a great sense of humor and a greater understanding of justice. He listened with patience, spoke with purpose, and walked through the world with conviction and strength. He gave his time freely, mentored with generosity, and stood up for what was right – even when it wasn’t easy and when others often gave up.

We will miss his wisdom. We will miss his laugh. We will miss the passion and assurance he brought into every room. But more than anything, we will miss him – his presence, his laugh and smile, and how he made our community a better place.
