Can you check my letter of recommendation?

To whom it may concern:
I supervised Maria as a waitress in HOTEL AA from September 20010 to May 2011 and eventually in later times to the present.
In her work as a waitress, she was always attentive to the tasks entrusted to her, performing them in an effective and responsible manner, and always being attentive and pleasant in servicing the customer.
Also consider her a person capable of performing any task that is proposed in a successful manner, knowing solve any problem she face.
For all the above and my personal experience with her, I can assure you also meet the objectives that you mark it in a completely satisfactory.

Sincerely,

Patricia...
