The story of A1 Advertising is as much as a Her story as well as its history. Ms. Rosario T Avila-Santiago took over the reins of the company on Aug 13, 2000, with her son James Paul Santiago as her herald and operations officer. Little did they know that the once backyard pop shop would turn out to be one of the country's most promising and reliable full-service advertising company. She then banded together with her other children who were skilled in their respective fields which resulted in transforming a single proprietor company into a full-fledged corporation.
