After Brilliant Babies in Menlo Park had been running successfully for five years, and wanting to create a similarly engaging, bright and fun playspace in Los Altos, Mary Heffernan brought PLAY! to downtown Los Altos in March 2012. PLAY! was designed by Mary - from the hand made ABC wall to her vintage BRIO train collection - to create an indoor play area, a sort of hybrid of a children’s museum and playground- where parents could stay and play with their children, meet other parents and let the little ones socialize. As a busy mother of four young girls, Mary created the PLAY! hours and special classes to be drop-in, so whether parents come by for a quick play date or kids’ yoga, they don’t have to adjust their lives around a schedule. PLAY became a popular meeting place for many local moms and new friendships were forged in it's bright space. PLAY was sold in 2014.
