When I arrived in USA in 1997 I began a new career as a bookkeeper in the phone company and after that in the pharmacy. Later, I worked as a medical assistant in a family doctor’s medical office and front desk at office of psychiatrist office.

Currently I am working as a marketing director in the dental office of Dr. Umanoff. I check patient’s benefits and enter insurance information into the computer database.
