Several years ago, Dr. Mortimer composed a typed, detailed job description on Jill's behalf. It was 20 pages long!

As Dr. Mortimer often says: "I am a very, very lucky boss to have such a competent and charming Office Manager, Medical Assistant, Receptionist, Secretary, and Billings & Collections Person! – On behalf of my patients and their families, thank you again, Jill!"
