After studying Psychology at Bombay University, conducting door-to-door surveys and learning to drill borewells in rural India, Sunil decided to put the combined skills thus acquired to advertising. He got his first copywriting job in 1990.

He worked at a frankly alarming number of agencies - Dattaram, Clarion (now Bates), Trikaya Grey (now Grey Worldwide), Nexus Equity (now part of the Lowe Group), Cosmos Advertising - before finally setting up his own creative consultancy, The Flea.

Much to the chagrin of his clients. He has consistently won accolades for his work from CAG, A&M, IAAFA and AdClub Bombay, British D&AD, New York Festivals and Graphis .

He is a part-time poet and a frustrated bassist.
