Mr. Rivera was the best choice I could of made for this. He helped me serve papers out of state, which I thought would be an impossible task. I provided him with the information he asked for and he took care of business. He was always available to communicate and made the whole process easy. I’m so thankful for him and his help.

I received the info I needed about my missing family in less than 20 hours with pictures. It was a huge relief to know they are ok and doing well. It was affordable, as I have to budget income from paycheck to paycheck. I have to give 5 stars for that! More...

I got divorced earlier this year after two years of marriage. For me, it came really out of the blue. My husband came home one night and told me that he had fallen in love with someone else; when I asked about our marriage, he said it was over, i was shocked everything gone. I couldn’t comprehend anything but I was able to get closure to my husband because i love him and couldn’t just let go, i contacted SPYNETING @ yahoocom). These people have surveillance experience and will have a good idea of all the relevant privacy laws and hacking solutions. I saw all the positive recommendations and I decided to make inquiries too and got what i needed urgently. I have no regrets giving this recommendation. More...

The service was very professional at the beginning. He was willing to listen to 'why' I needed his service. However, once the money was wired, he changed his attitude towards me and the project.

He was not responding to most of my messages towards the end and reluctantly answered if I actually asked him at least twice. Also, he was not really updating me on how the case was being handled which was really frustrating.

To sum up, it started off well and ended quite badly. The quality of the work he has done wasn't bad but he didn't really give me the answers that I wanted in the end.

Hope he doesn't do this to the rest of his clients.

Reply from Rivera & Associates Private Investigators

Jaime, I am sorry you found no value in the information I may shared with you however in true transparency, I must point out that at no time did you choose to hire our services, pay for any information shared with you for absolutely free and whatever information was shared with you came from the limited amount of information you provided via text. I never even verified your true name. This information was acquired through proprietary databases and confidential sources only afforded to licensed professionals, which needed to be validated and verified though the very investigation you chose to decline and not hire us to perform. I trust you have resolved your questions at that time and understand you chose not to hire us.

Roberto Rivera managed to serve the defendant, who was very hard to find and was out of county, which enabled me to finally secure the court date. There was some delay in obtaining the payment receipt due to them being out of town. Beside this small issue I would recommend this agency for your PI needs. More...

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!!! More...

As a former Law Enforcement Officer from Northern California I feel qualified to recommend the services of Rivera & Associates to anyone seeking remedial responses from ongoing disputes whether they are Civil or Criminal. Roberto is very well connected in Santa Clara, California and the Santa Clara County area.

Roberto is extremely effective in exhausting all levels necessary to fulfill his obligations with the scope of the law. He has the timely “Integrity” to get the job done in a proactive manner. What you come to Rivera & Associates for is intellectual integrity and the results are phenomenal. It is primal to say that we are all accountable to get the facts straight no matter where they may lead. The laws of economic gravity are you get what you pay for. With the information that you provide to him in the course of an investigation, he will give you feedback needed to make an informed decision. The bottom line here is there is no bottom line of what can be accomplished. Do not caught up in it, don’t get emotional, go with the numbers, this is a science.

It is very easy for clients to voice their feelings via a blog post without taking into consideration the overall circumstances, abilities, and legal ramifications set as priorities necessary in order to do the job that he is capable of doing and that you are requesting that he do. In my experience and with all due respect for Roberto in my unbiased opinion, what it comes down to is providing the information to locate, track down, and come to conclusions (whether they be in your best interest of not) as to the outcome of any and all proceedings. Ultimately Roberto Rivera offers and gives superb service with request’s that will exceed your expectations. Negative comments and feelings are not necessary, and very easy to produce.

As for me personally, I am just another satisfied client going through a divorce, having trouble locating an ex-wife and getting her served to appear in Court, and with a young daughter involved, this concerns me a great deal.

After leaving a few reviews I was contacted by Roberto and finally given the full results of his work, along with a complete refund. While I feel that better (ok, ANY) communication would have made this a completely different experience, I do appreciate that he was willing to acknowledge the problem and honourably issue the refund.It does appear that the R&A team are skilled at what they do - perhaps just too busy? Or maybe we caught them in a bad time.Bottom line: We were out of options, and R&A could have just taken the funds leaving us with no recourse - but instead they chose to fully return the deposit to make things right.

Our Background services include developing evidence to support a claim or a defense, identifying, or locating witnesses. Our extensive range of domestic and international searches / information will help in deciding whether to seek legal action, employ alternative dispute resolutions, negotiate a settlement, seek a restraining order or verify potential risks and threats. These searches are performed by trained and experienced Record Researchers.

Surveillance is conducted when there are reasonable grounds of suspicious or fraudulent activity, and when other methods have been utilized but have found to be ineffective. The person requesting the surveillance should weigh and balance the need of the surveillance to the privacy interests of the subject of the Investigation.

The Global Positioning System (GPS) trackers that we use for investigative surveillance are different from the GPS devices on your dashboard or windshield that makes sure you don’t get lost. These investigative GPS trackers show you exactly where a vehicle, asset, or person is located and will track and document the historical position of that vehicle, asset or person over time. Most GPS Trackers have software that allows Investigators to generate a detailed GPS Tracking Log of the vehicles historical location(s).

GPS tracking law is determined at the State level and each State’s laws are typically different. It’s part of the Private Investigator’s responsibility to know the law and ensure that the device is being used in compliance with the current law. Both the client and the Investigator could be liable if the GPS tracker is not used appropriately.

​California Penal Code section 637.7 prohibits "individuals from using electronic tracking devices to determine the location or movement of a person with the exception of registered owners, lessors, or lessees of vehicles to use electronic tracking devices to track their own vehicles."

We will require the client to show proof of registration and must sign a written authorization that grants the Investigator permission to install the tracking device.

Almost everyone is traceable; you just need the tools, knowledge, time and techniques to get the person found. Rivera & Associates has just those tools as well as specialists specifically trained to locate missing persons. Our Missing Person Investigators will work with law enforcement, network with non-traditional resources such as non-profit missing organizations, conduct online database research and utilize offline resources to pick up where the police may have left off. Many police agencies are not equipped to spend an excessive amount of time on an investigation, especially when the leads have run out. Rivera & Associates will dedicate the time necessary to find your Missing Person or Locate.

Our Investigators have access to some of the best online proprietary databases, public record resources, open-source Intelligence (OSINT) tools and investigative networks in the world. Some of these private databases are not available to the general public. Only detectives and licensed investigators have the credentials to access them. These online and unique databases span worldwide and can be cross-referenced to locate just the person you are looking for.

What Do We Need to Find or Locate a Missing Person?
The more information you can provide the Investigator the better when trying to locate a Missing Person, Locate, Child or Runaway. If you have the full name, date of birth, birth certificate, social security number or former address or city that would give us a great start. But we will begin working with the information you can provide.

As a private investigator, you have to keep in tune with the ever-changing online social landscape. Trends are constantly changing when it comes to the wealth of information available to private investigators through social media and online sources. With social media at our fingertips, investigators have abundant access to information regarding every detail of people’s lives. This information can be obtained easily and almost effortlessly.

Social media is often used as a tool for insurance claims investigators to extract evidence while investigating suspicious claims. The subject may be bragging on their Facebook page about the deception against the insurance company and posting information and pictures, contradicting their limitations and restrictions.

After analyzing the victim’s Facebook photos and check-ins, investigators can gather additional evidence, beyond the traditional surveillance methods, which assist in successful investigations.

Social media outlets are commonly and routinely accessed by private investigators during the pre-investigation phase of any investigation. Before beginning any investigation, it is prudent to review all social media outlets for information on the subject. Many people post to their social media and investigators are able to obtain information such as a physical description from a photograph, the subject’s schedule and appointments, possible associations, addresses, employment status and the list is endless.

Social media is a powerful tool, and as a private investigator, it can be used as an excellent source of information on the subject of an investigation. Don’t ignore the fruitfulness of the internet, as it presents a wealth of information that is, at most times, easily accessible and available.
