Career
His father, Alexander Teresio Marinaccio, was of Italian descent. Marinaccio attended Catholic elementary school and public high school in Enfield, Connecticut, after which he graduated from the University of Connecticut with a Bachelor of Science degree in Home Economics (he has told how he initially entered that course of study to be near a certain university co-ed). After college he worked at several jobs, then tried his hand at stand-up comedy with The Second City workshop in Chicago, Illinois.
From there he moved into advertising, working first as a copywriter at the firm J. Walter Thompson.
After stints at Foote, Cone & Belding, DMB&B, Doyle Dane Bernbach Needham, and Bozell Worldwide, he helped found LMO Advertising where he is the "M." His career in advertising has spanned 35 years. While working as a copy writer, he was urged to write a book about his near-obsession with the 1960s television series "Star Trek".
