Dimmsdale Senior Center is a senior citizen's nursing home located in Dimmsdale. It first appeared in the episode, "Kung Timmy".
This is a place where old folks who do not have the financial means to own their own home go to live. They may have also been forced to live here because of medical problems.
The exterior has a sign that says "Dimmsdale Senior Center" and the building itself is about one story tall. Another sign outside says "No running". Inside is a cafeteria with a few more signs and motivational posters which advertise a quilting class, a jazz dance, and a sock hop dance.
While Timmy Turner was practicing his kung-fu to beat up Francis, he overheard an old person calling for help from inside the Senior Center. The old people could not cut their steaks by themselves, so Timmy used his karate chopping moves to cut up the food for them. The old lady then asked him if he washed his hands before chopping up their steaks.
