Katherine Grace (Rounds) Weisman, 55, of Mount Kisco passed away on Apr. 20 with family by her side after a heroic and difficult battle with multiple myeloma.

Katie was born Sept. 24, 1965, in Bloomington, Ill. She graduated from Pratt Institute in Brooklyn with a bachelor’s degree in fine arts, and worked as a technical designer before becoming a full-time mom and autism advocate, most recently in her position as assistant to the chairman at the Children’s Health Defense.

Katie is survived by her wonderful husband, Doug Weisman; her three beautiful sons, Nick, Alex and Don; her mother and father, Elaine and Richard Rounds, of Brandon, Man.; her brother, Jon; sister-in-law Carla (Rafael) and brothers-in-law Lawrence (Amanda) and Roger. 

Katie meant so much to all of us, touching each of us in her own unique way. She was nothing short of exceptional when it came to advocating not only for her sons, but endless children and young adults on the autism spectrum. She singlehandedly changed the lives of many families, encouraging them to look at autism as a different and wonderful way to approach life, not as something tragic.

Katie was passionate about her work with the Children’s Health Defense and fought endlessly for vaccine safety and the vaccine injured. She was an active member of our community, especially within the Bedford Central School District, Special Education Parent Teachers Association (SEPTO) and Bedford Autism Spectrum Support (BASS). She loved her town, Mount Kisco, and took great pride in being a part of the Beautification Committee. The flowers that will bloom in front of the library this spring are thanks to her efforts.  

Visitation was at Oelker-Cox & Sinatra Funeral Home in Mount Kisco on Apr. 24. A memorial service will take place at a later date.

The Weisman family kindly asks that in lieu of flowers, a donation be made in Katie’s name to the Children’s Health Defense at There is also a GoFundMe page set up to assist the family at
