Michael Marino, a highly decorated former homicide detective with the New York City Police Department, is the Chief Investigator of the agency. Mike heads a staff of some of the brightest, most diligent professionals in the field. Our standards are kept high so each case, small or more intricate, is given the same quality of attention.


Investigations are conducted locally in the New York area as well as nationally and internationally. State of the art computer facilities provide enormous research capabilities. 


On two occasions, the agency has assisted in obtaining reversals of homicide convictions, where evidence obtained by investigators exonerated our clients after several years incarceration. Our agents are also trained in Mitigation Investigation for capitol offender death penalty cases.


Information is power. It is the company's goal to optimize our client's position under every circumstance.
