I started a letter of Rec for a previous employee but I do not have time to complete it. I need assistance revising and polishing what I have. I am writing for a previous employee who is applying to Nursing school. As mentioned she started school at FAMU for pharmacy but is attempting to switch her major. Aside from working with me as an employee and mentee sha has worked at a nursing home.
