From 1975 until 1987, Paetro was a recruiter and EVP creative department manager at several large New York City advertising agencies. In 1979, Paetro published her first book, How to Put Your Book Together and Get a Job in Advertising, which received its fourth revision in August 2010. This non-fiction work has been described as “the advertising industry bible and ultimate insider's guide to getting in and getting noticed".
Between 1986 and 1992, she published three novels: Manshare, Baby Dreams, and Windfall. In 1993, she collaborated with Dodd Darin to write the biography Dream Lovers: The Magnificent Shattered Lives of Bobby Darin and Sandra Dee.
In 2005, she began the first of more than a dozen collaborations with best-selling author James Patterson, co-writing 4th of July for the Women’s Murder Club series. Paetro explains in an interview that she and Patterson (who had also worked in advertising before becoming a full-time writer) had known each other since the 1970s. According to British newspaper The Sunday Times, of authors with the most titles to be at number one on The Sunday Times bestseller list over the past forty years, she ranks #16 with eleven separate titles in the #1 position.
Her garden, Broccoli Hall, has been featured in national magazines including House & Garden, Victoria, Country Garden and Country Homes. Broccoli Hall is on the Garden Conservancy Open Days Program.
