"I would tell someone who is considering becoming a nursing assistant that it is one of the most rewarding jobs you can have. There is just something about being able to help people who are unable to care for themselves."
"If someone were asking me about becoming a nursing aide, I would tell them it is one of the most rewarding jobs I have ever had.

Being able to spend time with patients and get to care for them, often when they are at their most vulnerable is a great experience."
"I love being a nursing aide. If someone were to tell me that they are considering becoming a nursing aide, I would be supportive of their choices.

It is a great career."
