Donna Bower Board Member

Donna Bower, a passionate advocate and dedicated board member of the aHUS Foundation, joined the organization during its early days when it was known as The Foundation for Children with Atypical HUS. Her journey was inspired by her son, Jonathan, who was diagnosed with aHUS in 1993. Donna’s steadfast commitment led her to become a board member in 2016, just before her son’s life-changing kidney transplant. Throughout her tenure, she has relished every moment spent connecting with patients and caregivers across the United States, forging bonds within the aHUS community. To Donna, the aHUS family is more than a community; it’s her extended family, and she continues to be an unwavering pillar of support within it.

Fran Pekor Board Member

Fran Pekor is a strong advocate for her 7 year old daughter, Brooke, who was diagnosed at an early age of 6 months old. As a parent and caregiver of a child with aHUS there are many challenges and stresses to overcome. With the wonderful support of a team of doctors and with the aHUS foundation, Fran was able to see the light after her darkest days- when she held her 6 month old daughter as she went into cardiac arrest. She prayed for Brooke’s heart to start beating again for 16 minutes. After being able to connect with another mother in the aHUS community, she found comfort for the first time in weeks while her daughter lay in an induced coma. After making that connection, she knew she wanted to be an advocate for the aHUS community and help others dealing with the same struggles. Fran’s goal is to see the children with aHUS live a long and healthy life. “I believe with the aHUS foundation we can raise awareness, and provide education on this ultra rare disease, while offering support to all those diagnosed with aHUS.”

Joining the aHUS Foundation in 2015, Alyssa has dedicated herself to connecting with fellow patients and caregivers. As the driving force behind merchandising, she combines her personal insight with unwavering dedication to enhance the lives of aHUS-affected families.
