GENE KOELBEL, IN MEMORIAM
Sewall Board Member for over 60 years
Gene Norgren Koelbel served Sewall’s mission for more than 60 years. Gene Koelbel’s parents connected her to Sewall’s legacy as they began support in the 1940s. Gene and her parents spearheaded the development and construction of Sewall’s first clinic facility at 1360 Vine Street in the early 1960s, and together with Sewall’s board and capital campaign committee, worked together to move Sewall to the expanded school facility at 940 Fillmore Street. As her health waned in the past year, Gene’s membership on the Program Committee remained steadfast. The committee moved their meetings to her house so she could still participate! Gene and Walt Koelbel’s support has touched each and every corner of Sewall. Their support of Fragile X research as it began with Dr. Randi Hagerman (now of the MIND Institute in California) put Sewall’s Diagnostic & Evaluation Clinic on the map. Her support of Sewall’s mission as it evolved from a therapeutic mobility clinic to a nationally recognized inclusionary education resource is unparalleled.
Gene, you will be forever missed and appreciated.
