Holmes Detective Bureau was founded in 1928 by Edward Z. Holmes, who served in the United States Secret Service through the terms of four Presidents. Utilizing the investigative and protective skills acquired during his distinguished public service career, he joined with other members of the local, state, and federal agencies to open the original office on the second floor of the Pioneer Hotel in Rockaway Park, New York. Mr. Holmes later became a consultant to the NYPD in techniques that would eventually be known as the science of gun detection.                                                   

Since 1928 HOLMES has been providing professional investigative and security services for the public sector, corporations and law firms. During over the 84 years we have been in business, we have maintained an excellent reputation in the security industry. By developing associations with professionals in all phases of the industry, we are able to provide a complete array of services including corporate, civil and background investigations, latent fingerprint examination, forensic document examination, electronic security countermeasures, evidence identification, and polygraph examinations.

After working on a case, HOLMES doesn’t just bill and forget. Once the investigative phase of a case is completed HOLMES investigators know how to present competent relative testimony as convincing witnesses. All of our investigators have garnered hundreds of hours of courtroom experience testifying on behalf of our clients and the People.  We are pleased to announce that Mr. Barry Goldblatt, (retired lieutenant  New York City Police Department), now heads our Polygraph Division. Mr. Goldblatt, a former detective in the NYPD Polygraph Unit  joins Mr. Dan Mahoney, who retired as a captain in the NYPD and heads our Investigative Unit. Mr. Mahoney directs our staff of highly competent licensed private investigators, all of whom possess a wide range of experience gained in the NYPD’s Detective Division. Mr. Mahoney is also a best selling author of eight police procedural novels.
