Seeking fun, responsible college or grad student as summer sitter and homework helper for my 11 and 13-year old near downtown Palo Alto. Must have Stanford affiliation, love math, science and the Vlog Brothers. We'll be reviewing algebra (and Spanish vocab, a plus!). I'll need help driving back and forth to camps, so car and clean driving record a must. Approx. 15 hours/week M-F afternoons, some extended evenings. Contact Leslie at lrgc@sbcglobal.net
