I wish I could give Margarita and her team 10 stars! I'm an attorney licensed to practice law in the Commonwealth of Virginia. I first met, and worked with, Margarita and the Professional Legal Resource Group Inc in 2013. And since then, she and her company have been my absolute primary go to for the investigative needs of my Clients. Margarita is honest, reliable, very diligent, and hard working.

She's on task from the word, "go" and cares a lot about the satisfaction of her Clients and the quality of her work. I appreciate all the help that she's been to my Clients, thus far and look forward to many more years of working with her.

Hired to serve wife with divorce papers. Wife had ran away with another guy and was dodging service. Company found her address quickly and perfected service within the week from being first called for help. While serving, I was provided with constant updates of the situation through photos and videos. Excellent use of money to accomplish my goal with very pleasant customer service. Thank you so much!

I am very happy and impressed with PLRG, Inc. I worked with Margarita and she was very professional, efficient and knowledgeable throughout. With very little information I had, she was able to identify and locate the person of interest within one day! I highly recommend Margarita and the team at PLRG!
