I never wanted to talk about Tiffany in the past tense. Never in my lifetime did I want to imagine a life without Tiffany in it or even occur to me for that matter! Tiffany was a force to be reckoned with. I met Tiffany and her family when I was 8 years old in San Antonio at my first-ever Pompe conference.
Tiffany was someone that was easy to look up to, because despite her own personal struggles living with Pompe, she always handled it with poise and grace. She always thought of others before her own challenges.
Tiffany’s life mission was to advocate for people living with this disease and bringing awareness to others for future treatment. She worked hard for years to have newborn screening (NBS) at birth so if needed, people can start treatment as soon as possible.
Tiffany knew no strangers. She had an ability to make anyone comfortable around her like they had been lifetime friends. People trusted her and everyone spoke highly of her.
She was a beacon of grace, poise, and determination until the very end. You never knew what was going on in her life because she was always first to lend a hand. She was selfless and irreplaceable.
Tiffany has left a lasting impact on my life. From the moment I met her, I was memorized by her and still am. I will forever have her wise words in the back of my mind, so even though Tiffany is no longer with us, I will hear her advice for the rest of my life, and for that, I will be eternally grateful.

In 2003, I began working for the AMDA as the Patient AdvocateA person who helps patients and families navigate care, information, services, and support. More, and over the years my connection with Tiffany grew far beyond our shared work in the Pompe community. For 24 years, I had the privilege of knowing her not only through the AMDA, but also as a dear friend.
Tiffany was funny, warm, and full of joy. She loved her family deeply, adored her dogs, and cared for her friends in a way that made each person feel seen, welcomed, and valued.
One of the things I will always remember most about Tiffany was her generosity. She opened her home to me, and to other friends as well, when we did not have anywhere else to go on Thanksgiving or Christmas. That was simply who she was. She had a gift for making people feel like they belonged. She made difficult times easier with her kindness, her laughter, and her open heart.
Tiffany brought warmth and laughter wherever she went. Some of the happiest moments were the times spent together sharing stories, laughter, and friendship.
Tiffany gave so much of herself to the Pompe community through her work with the AMDA. She cared deeply about patients and families and worked tirelessly to make sure they felt supported, informed, and less alone. Her compassion, dedication, and vision helped shape the AMDA in meaningful ways, and her influence continues to be felt in the work of the organization today. She was not only a leader, but also a steady and caring presence for so many of us.
I feel very grateful to have known Tiffany for 24 years and to have shared so many memories with her. She touched countless lives simply by being who she was, generous, loving, funny, and real.
Tiffany is deeply missed and will always be remembered with love, gratitude, and affection.

About Tiffany
Tiffany Laurel House was diagnosed with Pompe diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha... More at age 12 and told she would not live past 20. She defied those expectations in every way imaginable: celebrating her 42nd birthday in January 2025, earning a law degree summa cum laude, becoming the president of the AMDA and chair of the International Pompe Association, and spending her life transforming the global rare disease community.
Despite severe respiratory decline requiring 24-hour ventilation, Tiffany lived with extraordinary strength and grace. She was not a figurehead; she was the reason people believed in the promise and potential of the AMDA. She poured herself into the mission, working tirelessly and humbly, never seeking recognition.
Tiffany passed away on May 25, 2025, leaving behind a legacy far greater than any list of accomplishments. Her journey — from patient to global leader — embodied resilience, compassion, and the power of purpose.
