I was looking for a process server in the Bay Area and thank goodness I found Rivera & Associates! If you need a process server, he is your guy. Communication is excellent and the price was also reasonable. Better than others I saw online. I would recommend to anyone!

After engaging the services of Rivera & Associates I was very surprised at the speed with which Roberto reported back to me that he had retrieved detail in formation. I was even suspicious. Upon reviewing his report I was very surprised, even disturbed, at the level of detail that could be obtained in such a short period of time. Kudos to Roberto! He was very professional and very fast. I plan to ask for his services again.

I was only given a short time to serve and file before my court date. I put a request for a process server through Thumbtack and was supposed to get 5 quotes. I got an immediate response from Roberto of Rivera & Associates. I did my own research on his website and was impressed with the company and what they had to offer. I called Roberto and he gave me a great price that was worth every penny! With his assistants that are located near and far, they were able to get my paperwork served and processed in a short amount of time. I am thoroughly impressed with Roberto and his team. I don't give 5 stars out freely when I do reviews, Rivera & Associates deserve the highest ratings possible. This has provided me a huge amount of relief during a difficult time with custody and court. Thank you so much Roberto and all your staff for all your help! I greatly appreciate it!!!
