Denise Lichliter Keller, founder and president of Western Maryland Investigations and Surveillance, LLC. established the company in 1984 after retiring from the Maryland State Police. Western Maryland investigations is capable of placing investigators wherever your needs may arise. We are available twenty-four hours a day seven days a week.
We utilize the latest hi-tech photographical and video equipment to assure you the best photo documentation as evidence in support of your case. Our staff consists of experienced investigators all having ten plus years experience and some are retired police officers bringing their years of expertise and “contacts.”


Our reputation speaks for itself. Thirty years and going strong. This is not a part time job, this is our only job! There are many who dabble in the P.I. business but they soon fizzle out. Not us, we have outlasted our competitors because, we obtain the facts and only the facts. Our investigators document every little detail which is constantly being entered into our data base for future use. Do you know another company who can return to an address six months later and know the dog's name? We have! Know before hand the defendant is evasive? We do! We get the job done.


Western Maryland Investigations & Surveillance is a full-service detective agency. While our service area focuses on the Maryland, Pennsylvania, and West Virginia Tri-state area, we also provide nationwide investigative services.>>READ MORE
