How much a week does Magellan Health Services pay a person a year that does treatment plans?

I know someone that works there and I want to know how much money they make but they wont tell me. This person has been working there for seven years. I believe they are lying about how much money there have thats why they wont tell how much they money. It is very important that I receive this information. Is there anyway I can find if I am not successfully on here
