About Our Group

Brenda Slama, Tim Geels and Nancy Carlson started Heartland Fragile X Alliance in 2012 to support families in Iowa and South Dakota. As parents of children with Fragile X, they wanted to provide a place where families can connect, share information and support each other. The group also serves as a resource for professionals working with individuals affected by Fragile X. Through fundraisers, educational seminars and charitable donations, the group hopes to be able to provide financial resources for families to access Fragile X clinics, like the one in Iowa City, IA.
