(NBC News)
"In recognition of his heroic acts and selfless deeds"
(City of Los Angeles)
"The most televised PI in the world; hundreds of media situations"
(Daily News)
"My deep appreciation… without hesitation, you neutralized the assailant... you prevented serious injury to the single Deputy who was outnumbered at the scene"
(Los Angeles County Sheriff)
"The real 'P.I. To The Stars'; they keep his card handy"
(Private Investigator Monthly)
“My personal thank-you for assisting the State of California in the re-write of our PI Licensing Test (three long days spent in Sacramento)!”
(Chief, State of California PI Licensing Bureau)
"FAR more experienced than the others but surprisingly affordable"
(Chamber of Commerce)
“Your interview and polygraph examination got (convicted Federal sex criminal) to admit to committing several other sex crimes, of which he had swore to us denying them only a few hours earlier; outstanding work”.
(Government agency)
"Thank you for saving me! / best PI on earth / my protector / thanks again for being my guardian angel / top-notch service / you rate 5 stars! / best bodyguard ever / fabulous job in helping me / awesome PI! / best PI / thanks for uncovering the mysteries/world's greatest bodyguard"
(from dozens and dozens of displayed autographed photos from celebrities)
"Called upon by government agencies and major corporations that can choose any and want only the best"
(USA Today)
"Well-respected; a leader; in nation's Top Ten; recognition well-deserved"
