Louis G. Santiago was born in Ponce, Puerto Rico and grew up in the Alfred E. Smith housing projects of New York City among the street gangs and characters that inhabit his writing. He was a financial advisor at several prominent Wall Street firms for many years and moonlighted as an offensive lineman for the New Jersey Rams, one of the nation’s top semi-pro football teams.

After retiring from Wall Street, he succumbed to his passion for writing and published his first novel, The Ambassador’s Apprentice, a Cold War novel that explores the 1962 Cuban Missile Crisis. When not writing about the rousing exploits of Daniel Guerrero, his unconventional hero, Louis devours all forms of thrillers, as well as historical non-fiction. 

He and his wife, Viviana, live in New Jersey and have two sons and five grandchildren.
