Nanny Needed

We are looking for a great nanny for 2 children in Kensington. We would prefer someone who could help out with light housekeeping. We would prefer a babysitter who has their own car, who does not smoke and who is comfortable with pets (we have a 75lbs golden retriever, very friendly). Looking for help picking our son up from school in Bethesda and then helping with getting the kids to after school activities. Kids are 11 and 13 and very self sufficient. Thank you!
