Maria is Bobby and Ronnie Anne’s mom. As a nurse at the city hospital, she’s hard-working and even harder to gross-out.

Maria is the voice of reason in the household and is known for her can-do attitude. She doesn’t always get to spend time with Bobby and Ronnie Anne, but when she does, she makes that time count!
