I am a personal injury attorney who has routinely retained Excell Investigations for my investigative work including process service, defendant and witness locates, and asset searches. They have been very prompt with my orders and always delivered the expected results. At times they have been successful in serving very evasive witnesses. Compared to other companies I have used in the past these guys are top notch. I will continue to use their services for my office’s needs and recommend them to others.
