About Us

Jessica Leving Siegel founded The Center for Siblings of People with Disabilities in 2019 after receiving an overwhelming response to the publication of her book, Billy’s Sister: Life when your sibling has a disability--a picture book based on her experiences growing up with her brother, Billy, who has autism. Before launching the Center for Siblings, Jessica spent over a decade working in nonprofit marketing and communications. She holds a Master of Business Administration degree with a focus on nonprofit management from Indiana University's Kelley School of Business, and a bachelor's degree in journalism from Boston University.

A veterinarian and pathologist by training, Sandra recently retired from a 3-decade long career in the pharmaceutical industry. She is now better known as the spirited nomad behind The Old Woman Who Lives in a Van. Having traded her microscope for a Glampervan, she now spends her days exploring all that North America has to offer by road - and writing about it for her community of loyal fans (that is, when she isn't under COVID-related stay-at-home orders).  Sandra is also the mother to seven (now-adult) children through birth and adoption, several with special needs. She spent many years on other non-profit boards, including African Cradle, Inc. and Ethiopia Reads. She is also a volunteer birth doula.  She is proud to now bring her support to siblings.

Aimee Halstuk has never let her physical disability get in her way. She was the founder of Just Give Me a Chance, a social playgroup for children with physical disabilities, and has also worked as a kindergarten enrichment coordinator at JCC Chicago and as an activity instructor at the Center for Enriched Living. She loves working with kids and is passionate about helping with the Center for Siblings' children’s programming and development of educational materials.
