Hello, my name is Angie Ostermeier. I am the Business Office Manager at Heritage Health Mt. Zion. I handle all of the billing, human resources, accounts payable, accounts receivable, payroll, and nursing supplies. I am also an H to O trainer for all the employees. This is our Happy to Oblige customer service class. I have been in the health care business since 1990 and have been employed with Heritage Health since 2002. I truly enjoy my job.
