I am looking for someone who can do a plumbing job. Who do I contact about This?

You may ask the folks that go there. Many could be your neighbors and can recommend a good plumber

Hi there! Northshore Senior Center runs an employment matching program where we match seniors who have a need (like for plumbing) with others (also mostly seniors) who have this skill set. You can find more information here: http://www.northshoreseniorcenter.org/programsservices/employmentreferralprogram.aspx Thanks!

Probably a plumber. Certainly not the senior center.
