Robert was born in New York and as a youngster moved to California with his family where he now resides. Robert became an ardent reader of suspense novels and cultivated a passion for solving mysteries at a very young age. Twenty-six years ago he founded the Worldwide Intelligence Network which is an accomplished licensed California and New York Private Investigation company.
