Negative experience: I don't know how there are so many 5 star reviews. I needed to get someone's last name and address to file a small claim, and Eric promised he would get the info. I spenty $100 for him to tell me that he can't get the info.

Fantastic experience: Eric and his team are amazing, especially Monica, who was incredibly supportive throughout the process. I was dealing with a sensitive custody matter, and their work played a key role in helping me secure the outcome I needed to protect my children. They were thorough, discreet, and professional every step of the way. I’m deeply grateful for their dedication and highly recommend them.

Fantastic experience: I’m an attorney, and when my previous investigator—who was excellent—passed away unexpectedly, I was left without a reliable investigator. For some time, I had to work with a few mediocre firms until a member of my staff recommended Peterson Investigations. I couldn’t be happier with the level of care and thoroughness Peterson Investigations brings to my cases. I fully endorse their services.

Fantastic experience: 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.

Fantastic experience: I had to utilize the services from out of state. From the start the whole process was clear and the mission was accomplished as fast as it possibly could have been. They were up front with the pricing and there was no games or hidden fees/charges. They were very professional and updated me constantly on the case. If I had to, I would definitely utilize the services again. Thank you Eric, for all the help 3000 miles away!

Fantastic experience: Mr. Peterson was very helpful, fast and efficient. He helped my family. He even refunded us some money when he didn't have to do as much as estimated. We are grateful to him.

Fantastic experience: I spoke with Eric regarding a background check report. He was very good with quick response! I only had the guy’s name, possible residing cities, and age range. Eric did a few searches but there was no result. Eric decided not to charge me for the searches. Not only that, he refunded me for the background check fee the next day early in the morning. He also updated me on it. Now, that is great customer service!!! I will definitely pass on his information to friends and family.

But if you need help, Eric and his team will take excellent care of you. Eric treats his clients like trusted friends. His years of experience as a law enforcement officer give you the upper hand in getting things done efficiently. He's trained in de-escalation while getting the results you need. We had a problem that needed assistance immediately. Eric was able to help us within the hour! Although my adrenaline was pumping, his calm demeanor settled my nerves.

He created a plan of action regarding the situation. Thanks to Peterson Investigations, the issue was resolved quickly and peacefully. This firm goes above and beyond their duty to serve. Eric is a man of integrity, intelligence and grit. He helped a friend of mine when her family was being harassed by a dangerous man. She told me the story of his brave assistance with tears in her eyes. This man is made of hero material.

Fantastic experience: Hired them for a simple matter, they got it done with no problems and were very professional throughout. They had me pay a retainer first (understandable in their line of work), and then they gave some of it back when the work was done. Hopefully I won't ever need a private investigator in California again, but if I do, I will use Peterson Investigations and ask for Eric

Fantastic experience: Eric's responsiveness and knowledge were crucial in swiftly and effectively resolving our issues. The white glove service provided by Peterson Investigations is 2nd to none. I wholeheartedly recommend Eric and his team – a solid 10/10 for their exceptional service and expertise.

Fantastic experience: I contacted Eric and he did what he sad he was going to do in the time frame he said he was going to. I had been hitting roadblocks in my case and thought of just giving up. I felt defeated. I called Eric and now I have what I need to move forward.

Fantastic experience: We all know people who like to talk about having integrity, but (unfortunately) it seems to be the increasingly rare person who instead shows it every day through their character and actions. Eric is undeniably that rare person. For years he has been the go-to referral for every one of my clients in need of his expertise. Authentic. Honest. Discreet. Effective. Reliable. These are among the most common words by those who have taken my recommendation and worked with Eric. Personally, the ultimate litmus test for providing a recommendation is "would I trust this person or service to work with my own family and dearest friends?" The answer to that question as it relates to Peterson Investigations is not only an emphatic "yes, I would," but also a deeply grateful "yes, I already have and will continue to do so without the slightest hesitation!"

Fantastic experience: I contacted Eric to locate an address for me. He was responsive and quick! Got me what I needed in a timely manner. They also offered to serve the paperwork on my behalf but I didn’t hire them for this service. They had the best price and I’d use them again.

Fantastic experience: We needed help in letting go of an out of town employee that we could not reach. We also needed to retrieve our equipment from the employee. It was very challenging getting this to happen consider the distance between us. Eric was so helpful. He worked with us to help us to deliver a notice as well as retrieve the equipment. He was on top of everything, and very responsive. I would recommend him highly. Top notch professionals!

Fantastic experience: Peterson is the real deal, he was able to resolve my problem within less than twenty four hours, awesome services. Would recommend 100%

Fantastic experience: We were scrambling to serve my ex. With less than a day to have him served, I couldn’t rely on a big process serving company or the sheriffs dept to expedite our case. I called Eric this morning and briefly explained the situation. 6 hours later my ex was served and he even text a picture as proof of service! Save yourself the time and stress!!!

Fantastic experience: Mr Peterson has a long and extensive background in law enforcement which I believe sets him apart from other PI’s when it comes to experience, but what I think really sets him apart from the rest is his ability to understand and connect with his clients and put them at ease.

Eric maintained constant communication with me and I could not be happier with his professionalism, attention to detail, and follow-up! He helped make a very difficult situation into something that I didn't even have to think about! I HIGHLY RECOMMEND ERIC AND PETERSON INVESTIGATIONS AND WOULD USE HIM AGAIN!

What a relief!

Fantastic experience: I don’t know where to even start and how THANKFUL AND BLESSED to have met Mr. Peterson.

We had 3 different police counties involve and they couldn’t help us, it wasn’t till we met Mr. Peterson and he was the one that helped us with the nightmare we were living.
