A San Francisco native, Rose Titcomb grew up babysitting her neighbors children in Pacific Heights. The demand for her service quickly outgrew her ability to fill the requests. Inspired, Rose started recruiting her friends to help. In 1998 Rose founded The Core Group. In 2005, with the help of her partner Chris, The Core Group became Wondersitter. Fifteen years later what was once a dream, is now a reality. Today, Wondersitter is recognized as one of the premiere on-call child care service in the United States and has provided WONDERFUL child care to thousands of families across the country.
