Board of Directors

Brian Silver,

The first days and weeks of knowing our son Justin’s Fragile X diagnosis, in 2006 when he had just turned 5, were dark. With this diagnosis, we learned my father-in-law, who had just passed, suffered with FXTAS and other family members were dealing with FXPOI. Early on, we made the decision that we could not sit back and wait for research to happen. Things brightened as my wife Shari and I had the fortune to be guided by the best minds associated with FXS. In the fall of 2007, we established the Justin Silver Fly With Me Fund to help families like ours get the same type of relief Fragile X clinic medical care provides. I am honored to serve as the President of the Board of Directors and will continue to do everything I can to help drive the NFXF mission and vision forward.

Larry Krantz,
Vice President

I am the proud father of an 18-year-old son, Tyler, who was diagnosed with fragile X syndrome at the age of three. He has as kind a heart as anyone I know. I also have a 20-year-old, Sasha, now in college, whose life has been affected by Fragile X. I am honored to have joined the NFXF board, and will work tirelessly to help the NFXF raise awareness, provide support to those affected, and assist in finding treatments and a cure. It is a mission of love for me!

Rajat Sarup,

I am with State Street Global Advisors as an Equity Analyst in Investment Management responsible for Utilities and Telecom sector research. I bring over 16 years of experience in the financial services industry with GE. I have an MBA and the Chartered Financial Analyst designation. My family is committed to bringing our experience with large corporations to serve the Foundation towards achieving its goals of providing support, promoting awareness and working towards a cure for Fragile X.

Emily Mack,

My husband and I are the proud parents to our blended family of five kids. We were introduced to Fragile X in February 2011 after our son was diagnosed at 2 years old. We are fortunate to work with Dr. Craig Erickson at the Cincinnati FX clinic and have participated in several research studies.

I have worked in corporate wellness as an exercise physiologist and wellness coach for the past 18 years at a large hospital system, on-site worksite wellness programs and in private practice. I’m driven by the desire to ensure that the NFXF continues to play an integral role in the lives of families, educating our communities, and facilitating research.

Jay Souder,
Development Chair

My wife, Anne, and I are the proud parents of Alec who was diagnosed with FXS in 1995 when he was 4 years old. After Alec’s diagnosis, 12 members of our family were also diagnosed with a variety of FX conditions. Our journey has allowed us to both laugh and (occasionally) cry but has always simply been accepted as our path and one that we readily embrace. And we believe that the future remains bright.  I spend most of my time consulting for Charles Schwab on corporate business development strategies and as a keynote speaker to our clients, on a host of financial topics.


Evan Davis

My wife, Alexis and I have four wonderful children: Sophie, Cece, Michael and Lila. Cece was diagnosed with FXS in 2009.  We are avid participants in the Fragile X community, from NFXF Advocacy Day, to fundraising, to local events, to FX Clinic visits at Kennedy Krieger, to an annual promotion of FX on the Today Show during Awareness Month. I will use my experience as a business owner, branding and marketing professional, and NPO board member to raise awareness and understanding, create opportunities for more research and funding, contribute to improving the lives of those living with FX, and ultimately to help find a cure as soon as possible.

Paula Fasciano

My husband Anthony and I are proud parents of two sons (Matthew, 19 & Benjamin, 13) with FXS. I also have a brother with FXS and sister with FXS, autism and seizure disorder. Matthew was the first diagnosed with FXS in our family, at age 2 in 1999. We live in Marlboro, NJ.

Since 2004, I have been CSN co-leader of the NJ Fragile X Community Support Group. I’m also the Northeast Region Leader for the NFXF CSN groups. I’m honored to give my time to volunteer to help grow this Foundation which has been my lifeline since 1999.

I work for Vanbridge LLC, a boutique insurance brokerage firm, focused on private equity firms and their portfolio companies.


Brenda Finucane
FXCRC Board Representative

As a genetic counselor and researcher, the focus of my work has been on genetic causes of developmental disabilities, and which led me to contact with hundreds of children, adults and families with FX over the past 30 years. The NFXF has always been a professional anchor and a wonderful resource for the FX community. I’ve been fortunate to serve on the NFXF’s SCAC, and now on the Foundation’s Board of Directors as a representative of the FXCRC. I currently serve as the Associate Director and Senior Research Investigator at Geisinger Health System’s Autism & Developmental Medicine Institute in Lewisburg, PA.

Abigail Gaunt

I joined the Fragile X world when my 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, I am the Assistant Dean of Students at Tulane Law School.  I also have experience as a Director of Student Conduct, a litigation associate, a law clerk in the U.S. District Court for the Southern District of New York and the United States Court of Appeals for the Fifth Circuit. I am also Outreach Coordinator for New Orleans Special Olympics.


Joe Garera
CSN Board Representative

My wife Leslie and I are proud parents of our son Nick. In 1995 at 22 months old Nick was diagnosed with FXS. Becoming educated became our passion and the NFXF gave us the direction and material we needed to get our journey off on the right foot.

In 1997 I started the now Tri-State Fragile X Alliance. Hosting events has been my focus to bring Fragile X to the region. I’m the MidAtlantic CSN Regional Leader. As the CSN Liaison to the Board of Directors, I’m humbled and honored with this opportunity to represent the members of the CSN, a pillar of the NFXF.

I’m a retired firefighter, active in our church and work as a safety director for a construction company.

Mark Gershenson

My wife Caryn and I are the proud parents of two wonderful children.  Our son Corey is 19 years old and has Fragile X syndrome.  Our daughter Brette is a typically developing 14-year-old, and a fantastic role model, advocate and sister to Corey.  I have been fortunate to enjoy a rewarding career in consumer goods marketing in St. Louis, MO, where I was born and raised.  I am honored to be part of the NFXF Board and look forward to leveraging my extensive marketing experience and energy to further the NFXF’s mission around awareness, community, research and the ultimate goal of finding a cure.

Mike Makris

My wife Tina and I were blessed with our son Hayden in 2005, and in 2007 discovered he had Fragile X syndrome. After the initial shock and a few months of unanswered questions, my wife contacted the NFXF, who put us in contact with the Fragile X Association Michigan. After moving to San Antonio, we started the Fragile X Alliance of Texas in April 2010. We’re proud to have grown FXAT from its roots in San Antonio to include Houston as one of our chapters. Now I am honored and humbled to have been asked to sit on the NFXF Board of Directors.

Howard Pollock

My wife, Frandi Mars and I are the proud parents of three beautiful children: Arielle, 22; Ryan, 15, and Sydney, 12. Arielle and Ryan both have Fragile X syndrome (FXS); Sydney is unaffected. My wife and I are so grateful for the information and network provided through the Fragile X Foundation and the connections we have made are priceless. We cannot change Ryan’s genes but we can modify the gene expression. I have worked in association and non-profit management for the 28 years and am excited to share my experiences with the board and team furthering the truly wonderful mission of the NFXF.


Stephanie Sherman

I have been involved in research of Fragile X for my entire career as a scientist. My early work helped to identify the unique aspects of the inheritance of the FXS prior to the discovery of the FMR1 gene. Since then, I have focused on studying the Fragile X premutation, which will hopefully lead to prevention and intervention. I have had the opportunity to help form the FXCRC in collaboration with the NFXF and the CDC. I have enjoyed working with a great team of clinicians and researchers, all dedicated to finding ways to better care for families with Fragile X.

Donald Schalk

Donald Schalk

Our family was devastated when our grandson Nathan, was diagnosed with FXS. My wife and I were unflinchingly determined to educate ourselves. We have chosen to help anytime, anywhere and anyhow.

I am a retired corporate executive, currently teaching MBA students at a local university. I volunteer in my community and church. I hope to utilize my marketing, strategic planning and leadership strengths to help the FX community.

Grandparents can have a positive impact if they can travel alongside their adult children as they navigate the journey of Fragile X.


Carolyn Tomberlin

As mother of two Fragile X young men, the NFXF has been central to our lives since the day we received our first diagnosis in 2000.  Our boys became my “True North”, while the NFXF and everything it offers has become our “Compass.” I am honored to be serving with such a talented and passionate board. I am particularly thrilled to be leveraging my professional acumen as an Intellectual Property Manager -Licensing Executive to help the Foundation open new doors and evolve new strategies for an even stronger, brighter future.
