Very professional. I encountered some difficulty in identifying the right address to serve the defendant in my case and Adamant Process worked closely with me to resolve the issue and ensure my documents were served on time. I recommend inquiring ahead of time about potential fees if extra work is required, but certainly the most cost effective option I came across in searching for a process server. I will be reaching out to them if I need documents served again in the future.

Brian (owner), did a good job serving my legal docs. I just got a little bit impatient with him for not communicating/updating me through the process. While I understand that he is busy, communication is important. I still recommend him, and will use him again. Thank you, Brian!
