The motto of Bay Area 2nd Mom is to "provide care when you can't be there." As such, it serves as a referral agency for nannies, babysitters, personal assistance, and housekeeping. Clients include single families, as well as hotel guests, and corporate employees. What it offers is security: Every applicant is screened and offered professional training, if necessary. All pre-screened candidates are experienced, and English speaking or bi-lingual. Screening includes extensive background checks, including DMV printouts, checking references, Social Security traces, fingerprints, and two criminal background checks. The well-developed Web site allows you to register online for whatever it is you want - be it a long-term Nanny or someone who needs only four hours notice.
