"I worked for a property management company in college. I assisted their staff accountant and controller each month with entering all of the rent payment, property utility, and maintenance financial transactions. I also helped compile quarterly and annual financial reporting. I am comfortable tracking detailed financial data, reviewing it for accuracy, and performing trend analysis."
