The Benign Essential Blepharospasm Research Foundation (BEBRF) announces the retirement of Charlene Hudgins as Executive Director and welcomes Angel Roberts as the Foundation’s new Executive Director.

After many years of dedicated service to BEBRF and the blepharospasm community, Charlene is retiring from her role as Executive Director. Throughout her time with the Foundation, she has helped guide BEBRF’s work and remained committed to supporting individuals and families affected by blepharospasm and related disorders.

BEBRF is grateful to Charlene for her years of service, dedication, and commitment to the Foundation and its community. We wish her all the best as she begins this new chapter.

As BEBRF looks to the future, we are pleased to announce that Angel Roberts will assume the role of Executive Director.

Angel brings new energy and perspective to the position, and BEBRF looks forward to working with her as the Foundation continues its mission of providing education and support, advancing research, and serving the blepharospasm community.

While this marks a change in leadership, BEBRF’s commitment to its mission and to the people it serves remains at the heart of everything we do.

Please join us in thanking Charlene for her years of service and welcoming Angel Roberts to her new role as Executive Director.


Forty-five years ago, one woman’s determination to find answers changed the lives of thousands of people living with blepharospasm. What began as a personal search for understanding became a global community built on hope, support, education, and advocacy.

On July 23, 1981, the Benign Essential Blepharospasm Research Foundation (BEBRF) was officially chartered as a Texas nonprofit corporation, marking the beginning of a mission that continues to impact patients, families, physicians, and researchers around the world.

That mission began with Mattie Lou Koster, a woman who understood firsthand the challenges of living with blepharospasm. In the spring of 1981, nearing the age of 70, Mattie Lou faced a condition that was still poorly understood, leaving many patients with more questions than answers. Rather than accept the uncertainty, she chose to take action.

Without an office, staff, website, database, or formal resources, Mattie Lou created a place where people could come together. From her home in Beaumont, Texas, she opened her doors to others living with the same struggles. She listened to their experiences, connected families, and created a space where patients could find understanding and support.

Those early gatherings in her living room became the foundation for what would become BEBRF. Shortly after the organization’s official formation, the first BEBRF Support Group Meeting was held in Tulsa, Oklahoma, beginning a network that would continue to grow across the country and around the world.

Over the past 45 years, BEBRF has become a source of hope and connection for the blepharospasm community. It has provided patients with resources, caregivers with support, researchers with collaboration, and individuals facing the challenges of this disorder with the reassurance that they are not alone.

This milestone is a celebration of everyone who has contributed to the BEBRF journey: the patients who shared their stories, the caregivers who provided support, the physicians and researchers who advanced understanding, the volunteers who strengthened the mission, and the supporters who helped carry the vision forward.

As BEBRF celebrates its 45th anniversary, we honor Mattie Lou Koster’s compassion, courage, and commitment to helping others. Her willingness to open her home and bring people together created a legacy that continues to inspire generations.

What started as one woman’s search for answers became a worldwide community united by hope.

With heavy hearts, the Benign Essential Blepharospasm Research Foundation mourns the passing of Mary Lou Thompson, a beloved member of the BEBRF family and a person whose life was deeply woven into the history of this organization.

Mary Lou was a truly special part of the BEBRF story.

As the daughter of our founder, Mattie Lou Koster, Mary Lou carried forward her mother’s vision and devoted more than three decades of her life to supporting people living with blepharospasm.

She believed deeply in the power of community and connection. Through her leadership, compassion, and unwavering dedication, Mary Lou helped ensure that patients and families had a place to find information, encouragement, and support — and that no one facing blepharospasm would ever have to feel alone.

Those who knew Mary Lou remember her as a passionate advocate, a kind friend, and a true force of nature with a wonderful warmth, energy, and determination. She gave her heart and soul to BEBRF and to the people this organization serves.

One of Mary Lou’s greatest wishes was to make sure that no one ever forgot the name Mattie Lou Koster.

We haven’t.

And we never will.

Mary Lou’s legacy lives on through every patient who finds support, every volunteer who carries the mission forward, and every person who discovers they are not alone.

We are forever grateful for her years of service, her compassion, and the lasting impact she made on this community.
