Laurie Bridges


Laurie and her husband, Will, are the proud parents of Caroline (full mutation) and Clark. Laurie has worked as an occupational therapist since 1999 and currently works in the Humble Independent School District near Houston. Not long after her daughter was diagnosed with Fragile X Syndrome, Will and Laurie began serving Fragile X families in the Houston area by forming an NFXF Community Support Group in 2011. She has attended five NFXF International Fragile X Conferences and was co-chair of the host committee for the 2016 conference in San Antonio.

Since the beginning of their Fragile X journey, the Bridges are thankful for the National Fragile X Foundation and how it supports families, promotes education and awareness, and puts a priority on research: “We keep moving forward and taking the next step. We are thankful for our Fragile X family because we are not alone!”

Kara Frech, BOD member

Kara Frech

Vice President

Kara and her husband, Steve, are the proud parents of two teenage boys, Andrew and Jason, both diagnosed with Fragile X syndrome in 2007. Upon diagnosis, Kara immersed myself in all things Fragile X to learn how to help her boys lead successful, fulfilling lives. The NFXF was and is her go-to source for this.

In 2012, Kara co-founded the Southeast Pennsylvania Fragile X Community Support Network group and continues to lead the group by organizing educational conferences, social events, and X Strides walks for local families.

Kara’s passion for helping others lead successful lives with Fragile X along with her skills acquired as a former management consultant and currently as a stay-at-home parent contribute to supporting the NFXF’s mission while serving on the board. “I am proud to serve as a board member for the foundation to further the mission of the NFXF to provide unwavering support while relentlessly pursuing a cure.”

Anthony Fasciano, BOD member

Anthony Fasciano


Anthony and his wife, Paula, and are the proud parents of two awesome young men: Matthew (aka Matty Fash), 24, and Benjamin (aka Benji), 18, both of whom live with Fragile X syndrome.

“These two boys never cease to amaze us. They have overcome so much, have accomplished so much, and still have so much to do. The NFXF has been a very instrumental part of helping us get them to where they are today. We have been affiliated with the NFXF since Matty was 2 when he was first diagnosed with FXS. My wife Paula has been the family pillar of strength with the Foundation, serving in various capacities over the last 17 years. One of the things I have enjoyed most is having the privilege of meeting so many wonderful Fragile X families along the way. The whole community is full of very special people.”

Anthony has over 30 years of financial management experience in both the public and private sectors and looks forward to serving the NFXF on the board.

If anyone has any questions about being a Fragile X parent, Anthony says, “Just ask. I am always willing to help and share what we have learned.”

Abigail Gaunt, BOD Member

Abigail Gaunt


Abigail joined the Fragile X world when her son, Mack, was diagnosed with Fragile X syndrome in July 2014, a few months before his second birthday. Today he is verbal, attends a mainstream preschool, and he just learned to ride a bike and swim — all accomplishments that seemed out of reach when he was first diagnosed. He is always the happiest kid in the room.

Currently, Abigail is the assistant dean of students at Tulane Law School. She also has experience as a director of student conduct, a litigation associate, and a law clerk in the U.S. District Court for the Southern District of New York and the U.S. Court of Appeals for the Fifth Circuit.

Evan Davis, BOD Vice President

Jacquelyn Coleman

Board Member

Jacquelyn and her husband, Paul, are the proud parents of two children, Maya, and Paul III, both of whom were diagnosed with Fragile X syndrome. When her son was diagnosed in 2002, Jacquelyn sought as much information she could find. One of the first resources she discovered was the book Children with Fragile X Syndrome: A Parents’ Guide by NFXF team member, Jayne Dixon Weber. It is a book that she still cherishes today. After learning more about Fragile X premutation conditions at her first NFXF International Fragile X Conference in San Antonio, Jacquelyn decided to get tested to determine her number of CCG repeats. She was surprised when she found out that she, too, has the full mutation Fragile X syndrome.

Jacquelyn and her family became involved with the NFXF Houston Chapter in 2013, and since then have participated in many local events and fundraisers, attended NFXF Advocacy Day and International Fragile X Conferences. Jacquelyn has worked as a workers’ compensation Administrative Law Judge for the State of Texas for the past fifteen years. She is motivated by the desire to raise awareness in the community-at-large about Fragile X syndrome, to help underrepresented people gain better access to clinical trials, and to help self-advocates have a better future.

Board Member

Denny and his wife, Marcia, are proud parents of Angela, 40, and Aaron, 38. Aaron was diagnosed with Fragile X syndrome when he was 10 years old, thanks to a very observant elementary school teacher. Aaron’s diagnosis was a real blessing as his education could have been a disaster! He had a wonderful functional education that helped him graduate from high school in Kansas City, Missouri.

After moving to Waverly, Iowa, in 2003, Aaron was able to live by himself with agency help and has a job in dining services at Wartburg College. Aaron also helps manage the Wartburg College football team, which is the true love of his life! There is a documentary called, “Not So Fragile” that shares much of Aaron’s journey.

“I am so excited to be a member of the board of directors for the NFXF! I’m hoping to learn and share a lot — both in experience as a parent of a Fragile X son and in wisdom gained from my fundraising career of 14 years. I look forward to continuing to learn more about Fragile X, especially in research for the full-mutation Fragile X adult!”

Emeritus Advisors

Randi Hagerman, Emeritus Director

Randi Hagerman

Developmental pediatrician Dr. Randi Hagerman co-founded the National Fragile X Foundation in 1984 and has helped guide the foundation ever since. In 2009, after more than 100 board meetings, Randi agreed that it was time to step aside and let others bring their expertise to the board.

There is no aspect of the NFXF that Randi has not helped shape. Her strength as both a clinician and as a researcher has informed the NFXF mission and strategic plan. She and her husband, Dr. Paul Hagerman, generously support the NFXF mission. While Randi is no longer a board member, she is active on the NFXF Scientific & Clinical Advisory Committee (see above) and within the Fragile X Clinical & Research Consortium where she represents the UC Davis Medical Center’s MIND Institute as medical director of the Fragile X Clinic.

Randi continues to be a sought-after speaker and her work has expanded from Fragile X syndrome to all Fragile X-associated disorders. Randi is continually on the go as an international spokesperson for Fragile X. Fortunately, she’s only an hour away from the NFXF headquarters by car and seconds away by phone when we need to call upon her for her guidance, advice, and wisdom.

Mr. and Mrs. Hollin

Harris Hollin

Harris enlisted during the Korean War and served as an Army combat officer earning a Bronze Star. He owned Lemmon Pharmaceuticals, now part of TEVA Pharmaceuticals. He is a Fragile X grandfather and founded the Conquer Fragile X Research Foundation, now part of NFXF, which supported Fragile X research in many countries across Europe and Asia. (Pictured: Mr. and Mrs. Hollin.)

Gene Koelbel

As a leader of the Sewall Child Development Center in Denver, Colorado↗, Gene Koelbel was instrumental in the early success of the National Fragile X Foundation through her support of and collaboration with Dr. Randi Hagerman in the early 1980s. Along with her husband Walt, Gene provided crucial financial support for early Fragile X syndrome screening.

She served on the NFXF board of directors throughout the 1980s and 1990s. Her and her husband’s financial support of the NFXF in 1999 was crucial to its successful transition from a very small and poorly staffed organization to the much larger and effective organization of today. Gene also stepped forward to provide major financial support of the NFXF’s 25th anniversary campaign in 2009.
