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!!!

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Typically my estimates would be a minimum of a certain amount of hours for the assignment requested, depending on the method of payment and terms of payment. I will draft a contract and request a retainer to start. Additional hours are available through further negotiation again depending on method of payment and amount of hours.
What is your typical process for working with a new customer?
I initiate conversation with clients via telephone or email. I ask them to make their detailed request, some of the subject's and case information and provide a budget they are working with. I can usually then review the information, ask specific questions and then provide a more detailed and educated quote for the specific services they are requesting.
What education and/or training do you have that relates to your work?
I am a graduate of Saint Francis High School and hold a Bachelors Degree in Criminal Justice Administration, with a concentration in Law Enforcement and a Minor in Sociology, from California State University. I have also completed subsequent graduate work in Criminology at San Jose State University.
