Client Tom M. 

Coeur d'Alene, ID

"Answered my call right away and got me scheduled. Very happy with the service and most importantly the results. Will use them again."

Client Sandra G.

St. George, UT

“Exceptional to work with! Answered all of my questions and were very patient throughout the process. My family and I really appreciate the extra time and attention to detail, it made a huge difference in our case. Thank you again.”

Jim Siebe,

Attorney At Law

“I highly recommend this outfit! They were extremely professional and are the most complete team of investigators with whom I have worked. The team has proven to be capable of working on multiple major criminal cases simultaneaously, with limited supervison. They provide great work product, it is comparable to having another attorney on board, especially given that they understand the notion of relevant evidence. I always get effective, ethical, accurate and affordable results.”

Scott Poorman, Attorney At Law

“We have employed Joshua J. Mason for various matters, from simple service of process to complex civil investigations. We have always received prompt and professional service, with high quality results. I would give Prevail Investigations my unqualifed recommendation.”
