"I have had the great pleasure of working with LMI (and the unfortunate experience of having LMI work with opposing counsel.) LMI is thorough, professional, and prompt and a delight to work with. They are always looking for a solution that will work."

Jeff Grant, Attorney,  Seattle, WA


"My practice includes a variety of cases: divorce with custody issues, civil cases involving employment discrimination and sexual harassment, and criminal defense. I have used LMI for years and the results of LMI investigations have contributed directly to the favorable outcomes in many of my cases. I strongly recommend LMI for any investigative needs."

Karen Unger, Attorney,  Port Angeles, Washington

"LMI Investigations has provided my firm with exceptional investigative services for over a decade. Linda is responsive and knowledgeable and her team of investigators always go the extra mile to provide outstanding results. I highly recommend LMI Investigations."

John Segelbaum, Attorney at Law


"As a private investigator in the business myself, I know good work when I see it! I use LMI for all my investigative needs in the Pacific Northwest. I have always been pleased with the quality service they provide and I find their enthusiasm is refreshing."

John Landers, Landers Service Company, Boston, MA


"I hired LMI to assist me in the trial preparation of a very difficult case. The outcome was highly favorable to my client... acquittal on one charge and a hung jury with the majority for acquittal on a lesser charge. The assistance of LMI was instrumental in obtaining these results. I have worked with LMI for a number of years and have always been impressed with the quality of their investigative expertise. An added bonus is their creative input, analysis of trial strategy, and their ability to find effective experts for combating questionable States' evidence."

Attorney Lenell Nussbaum,
Past President of Washington Association of Criminal Defense Lawyers (WACDL)


"I worked with LMI on a very difficult case that went to trial. The defendant was acquitted. Ms. Montgomery and her staff provided excellent assistance in all phases of trial preparation. The investigation was critical to the outcome of this case."

Attorney David S. Marshall
