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!

The fastest, most professional company that we’ve done business with! He was able to serve our person faster than the other company that we did business with! It was such a relief to work with someone as professional as Adamant Process Service!
Thank you!

Brian was very co-operative and flexible in getting all necessary documents from us to him, and friendly also. The fee was reasonable, in fact less than many other companies.
Sara was willing to meet with me and hear my story. She was not only very efficient and professional, going the extra mile to serve the order. She was also caring and supportive of the frustrating situation that I am involved in. Many warm thanks to Sara for the great job and how she dealt with me. Unlike most business dealings, I feel like I ended up with a friend.
