Christy Dunbar is the most unprofessional, rude, disrespectful person I have ever encountered running a business. Harmony Medical Billing in Georgia is a very unprofessional place to work. The owner Christy Dunbar do not have any people skills, she speaks to the employees like they are beneath the ground. This company has had a HIGH turn over in couple months. Because of the lack of training and the feedback and attitude from the CEO/Owner Christy Dunbar the employees have left and found other jobs with the medical billing field.
