For Doreen, it’s all about the numbers. She assists in billing, processing, accounts payable and receivable, and contributes to HR initiatives. She is well liked in our office because 1) she’s affable and easy to get along with; and 2) she delivers us our expense checks. Born in Puerto Rico and raised in Cape Cod, Mass., Doreen spent the largest portion of her adult life in New York City. While there, she logged 12 years in the advertising industry, where she handled studio billing and media billing for agencies in Manhattan.
