Dear Jimy Ortan,,
I have not worked with Jose Rodriguez in about two years but I know he is a good guy. We worked at a pizza joint together and he would always trade shifts with me if I had something else to do. One time the cook did not show up and Jose was willing to fill in for him. I would say he can be trusted and will likely be a good person for the job.
Sincerely,
Colleen
