” It was evident early on that our son Riden’s unique spirit makes this world a better place. He’s a happy, bright and beautiful little boy. I smile just thinking about his life’s potential. Without new treatments for PWS though, the outlook is clouded by the restrictions of PWS. I can’t just let PWS happen to him without a fight. We have the power within FPWR to fight hard against PWS and win!”. Jessica Stubbs Howard graduated from the University of Georgia with a degree in International Business. As the daughter of a fighter pilot, she grew up in various places around the world. Following a career as a corporate sales and account executlive, Jessica is now a stay-at-home mom.

Jessica and her husband Tom attended the FPWR golf tournament in DC in 2006 and were “blown away” at how professional and well-run the event was. Jessica said, “We felt the can-do-it energy from the other families we met and knew that this was a group we need to be a part of!'” Her experience at the first FPWR Hike the Hill event in 2008 inspired and empowered her to become more involved with the FPWR. Jessica lives in Georgia, with her husband Tom, their three sons, Riden (PWS), Cole, and Trent, and their rescue hound dog.

Tom Compere

In the words of Tom and his wife Renay, “Our most life-altering event was the birth of our son William and his diagnosis of Prader-Willi syndrome. The thing that has kept us going over the years has been the optimism that a cure for PWS will be found and that our son will have a normal life. What a concept! A normal life was something, until recently, that I took for granted.”

Tom says that his involvement in the Foundation for Prader-Willi Research (FPWR) has been a godsend. “It has enabled us to channel our anxiety into action. We have witnessed the amazing power of the will of a few individuals in the metamorphosis of FPWR from a good idea to an effective operating organization.”

Rachel Fernandez Hansen
Board Member

“When our son Pablo was a newborn, and we were still reeling from the shock of his diagnosis my husband and I learned about the FPWR. I remember the moment I understood the foundations work and mission. It’s as if a fog had lifted and a path had presented itself, our mission as parents was clear.”

Born and raised in San Diego, California, Rachel spent 15 years traveling the world as a flight attendant and chief purser with United Airlines before making Paris home with her husband, Reuben and her son, Elias. Her career as an international chief purser ceased with UAL’s Paris base closure in 2006. Realizing the mental and physical benefits of practicing yoga and pilates during her years in flight lead her to pursue her certification training as a Pilates instructor. Little did she know how much her knowledge of body, mind and muscle would become her starting blocks as she welcomed her second son into the world.

Rachel organized the first One SMALL Step walk in Paris in 2011, importing the idea that had taken root abroad. That first walk has turned into several walks in France, now Un PETIT Pas, and has forged a strong alliance between the FPWR and PW France. In 2012 Rachel attended a capacity building program for rare disease patient representatives involved at the European level in the development, approval, information and access to orphan drugs, pediatric drugs and advanced therapies hosted by EURORDIS. She has been in a unique position to reach out to other PWS families, while educating and inspiring others. Her international background and strong communication skills were put to work in creating a partnership between PW France and the FPWR, a model which she hopes to replicate throughout other European countries. She currently sits on the board of Prader-Willi France.
