Working with a NYC Private Investigator

Many people believe in what they hear, see and read in the media about Private Investigators. However, most of it can't be further from the truth. The Private Investigator or Private Investigation Firm you hire must be skilled, creative and persistent to ascertain the results you are searching for; not just show a badge!


Just because an investigator you speak with had previous law enforcement background does not always qualify them as the best investigator for the job. Many of these types of private investigators can tell you many "war stories" and produce very little results. At JL & Associates, Ltd. we screen all our investigators (even with former law enforcement background) to be the very best, in the area requested by our clients.


We are dedicated to personal attention, individual commitment and the most cost effective service. We guarantee that all of our investigations will be conducted discreetly and professionally. For your convenience you can contact a New York private investigator or a Long Island private investigator 24 hours a day/7 days a week.
