Liz Simons is chair of the Heising-Simons Foundation, which she founded with her husband, Mark Heising, in 2007. As a former teacher with an MA in education from Stanford University her interests in early childhood education are reflected in the work of the foundation as well as her long-time commitment to several California and national initiatives, including Stretch to Kindergarten, which she founded in 2009. She is the daughter of Giving Pledgers Jim and Marilyn Simons. Mark Heising, is a Berkeley-trained engineer and computer scientist holding six patents in cryptography, compression, and data communications. He is the managing director of Medley Partners Management, a private equity firm he helped form in 2004 to manage investments on behalf of Jim Simons' family. Their foundation has been strong supporters of the Environmental Defense Fund, the Bipartisan Policy Center -- where Mark Heising is a board member, the University of California at Berkeley -- where the couple met, and a myriad other education, science, and environment organizations.

The world we bequeath our children is changing in ways that we can’t predict. Mark and I have faith that our own children can pick up where we leave off and do the right thing, as they see it, with the legacy we leave them.
