    I called several companies in my search and had no positive response until I called LRI. I have worked with Brad for several months and have found him to be readily available and trustworthy. His advice and recommendations are always appreciated, I know he has a sincere interest in helping. The bottom line - I have received quality service at very reasonable price. I will definitely use this company again.

    Simply the Best
    Super quick. Super professional. Super thorough. While other special process servers had a wait of 3-5 business days before the first attempt, Brad made his first attempt the next day and was able to serve the evictions summons successfully within 2 business days! When dealing with evictions, time is of the essence and Brad approached this issue with the same sense of urgency as I did. Brad is a true business partner, and I could not be more satisfied with his service. -Erica

    Helpful and honest
    I wasn't sure if hiring an investigator was appropriate. I called Lawrence Ryan Investigations and they were super professional, open and honest with what they could help me with. It turned out I was not at a point I could use their help, and they were upfront about it. So when I do need their help, I will absolutely call them.

Describe a recent project you are fond of. How long did it take?
A frantic father called us from out of state trying to track down his girlfriend and kids. She had left the state with them, and he thought they may be in Chicago where she has relatives. He not only wanted to find them and see if his kids were safe, but he also had court documents to serve to her. Within two hours of the phone call, we were able to track down the girlfriend and kids at a motel. We served the court documents to the girlfriend and were able to report back to the father that the children were there and safe.
What advice would you give a customer looking to hire a provider in your area of work?
No investigations firm is the best at everything. Each has it's strengths. Take the time to find a firm whose strengths match your specific needs. Also, it’s not a bad idea to check with the state licensing agency to verify that a PI’s credentials are valid and there has been no record of disciplinary action against the PI. It is also good to check with the Better Business Bureau to make sure no formal complaints of misconduct have been filed against the PI you are considering.
What questions should customers think through before talking to professionals about their project?
At LRI, we pride ourselves on being the best at what we do. Having said that, clients who are well-prepared almost always get better results than those who use a passive approach. You need our eyes in the field and our investigative expertise to analyze the evidence. What we need from you is as much information up-front as possible. Don’t underestimate the value of inside information. Whenever possible, gather as many relevant facts prior to the investigation. Such information includes vehicle info, pictures, addresses, names, dates of birth, social security numbers, and physical descriptions. We are certainly capable of obtaining these facts ourselves; however, when we begin an investigation armed with these facts, things move along much faster. Also, it always helps to do some general research on investigations.
