I've worked with this Peterson Investigations quite often in a professional capacity, so I was already familiar with their level of efficiency and reliability. Recently, I had to use their services for personal reasons, and they delivered the same high standard of service I've come to expect. They were extremely responsive, communicative, and handled my request with a strong sense of urgency. Serving legal documents can be time-sensitive and stressful, but they made the process smooth and straightforward from start to finish. It's reassuring to know that whether you're working alongside them professionally or relying on them personally, they consistently show professionalism, attention to detail, and dependability. I wouldn't hesitate to recommend them. read more

We found Eric via yelp and took a chance. We have never hired a PI before. Our business had employee theft occurring and after months getting nowhere at all with local police and banking regulators he told us the deal and what would likely happen. He got a confession in 5 MINUTES, exactly the way he said might happen. He never promised but just gave his common experience and it happened exactly the way he advised. He didn't overpromise, if anything he over delivered. If you have no idea what to do if you have a crime or case and cant get anywhere with authorities I highly recommend Eric, especially for business owners. read more

I've used this company several times now and they always deliver! Made a mistake of hiring a "professional" process serving company last time and basically threw my money out when they weren't able to find the guy that needed to be served.

I can't say enough about the incredible service and expertise Peterson Investigations provides. After my husband's property was stolen from baggage claim at LAX, we exhausted every avenue we could to get it back. We were so lucky a friend recommended Peterson Investigations. Turning to Eric for help was the best decision we could have made. From the very start, they were professional, compassionate, and determined to help us get our belongings back. Their attention to detail and tenacity made all the difference. Thanks to their skill and persistence, we were able to recover our stolen items (in less than 24hrs)--something we truly thought might be impossible.

When I received confirmation they had been served, I nearly dropped to my knees out of dis-belief and joy! The team provided quality proof of service and a summary promptly. Eric was professional and his customer service was unmatched. I had a ton of questions and a couple requests. Eric listened attentively, didn't rush me and never made me feel as though I was a bother. I am thoroughly pleased with my experience with Peterson Investigations and eternally grateful for Jennifer who is a go-getter and absolute ROCKSTAR! read more

I wanted to find out about the background of one of my housemates. We developed a relationship, but he kept his background a total mystery, which unnerved me because I wanted to trust him. I hired Peterson Investigations to do some checking into my housemate's background. Before anything could be found, however, I called a close relative of my housemate and had a lovely and revealing conversation. I found out what I needed to know, at least enough to put my mind and heart at ease. No longer needing PI's help, I canceled my request for services and promptly received a refund. Grateful for PI's professionalism, I have requested assistance with another matter. Catherine S. read more

In a vulnerable position as a wealthy widow, I ventured into dating on Christian Mingle's website. I very soon found myself really engaged with a very charming, spiritual man, who shared quite a story! Concerned friends encouraged me to investigating some facts, in order to create trust. I found Peterson investigations here in orange on the web. Eric was able to reveal the many red flags that were suspected. Ultimately, this gentleman showed his, true intentions and asked me to wire him a great sum of money, to fund a complicated project. I am relieved, and with Eric's help, I'm confident of my decision to STOP the conversation. I am so grateful for the professionalism, and competence of Eric, who really had my back! read more
