    I wanted to leave a 5-star review for Brian Matthews as he is extremely kind, considerate,…read morethoughtful, and efficient in the way he converses with his customers. He responds fairly quickly and reached out to me during the weekend as well. I have conversed with other private investigators when doing research, but Brian was the one who communicated in the most empathetic and heartwarming manner (and understands the client's difficult position). All I can say is that he treats his potential clients with care like a concerned family friend and explains the pricing in a reasonable way. I will definitely be choosing him in the future.

    Very disappointed with this company's service. Paid this company $400 to serve one of my past…read moretenants. Owner says they serve 99% of all their attempts and I gave them the address of where my tenant was located and they saw the tenant but didn't serve the tenant due to their own fault. Therefore, they said they want more money to reattempt. I told them, once they serve him, I would pay more. It was their own fault for not executing and even took 2 pictures of the tenant but did not hand the serve materials so they should go back out and serve them but they didn't saying I needed to pay more when it was their fault. They said the man had greyer hair but other than that, he looked exactly like the picture I provided. They should go back out and finish the job but was lazy not to do it. Just worthless. Complete loss of money. Should have just used the Sheriff at a 10th of the cost. Don't like this company at all. I would use another company. Just stupid people that can't execute. Please stop making excuses with your response. You should take responsibility. The ID and the picture matches and it was your fault. Just own up to it. Stop making excuses!! I SUGGEST TO EVERYONE TO USE SOMEONE ELSE. THIS HAS AN OWNER THAT CANT ADMIT THEIR OWN MISTAKES AND MAKES EXCUSES. STOP PLEASE. Please do not justify yourself by saying that my comments omits important context. It is very plain and simple - YOU AND YOUR COMPANY WAS AT FAULT AND DIDN"T PAY ATTENTION TO DETAILS AND YOU JUST WANT MORE MONEY!! DON"T TRY TO JUSTIFY. I TELL IT LIKE IT IS!!! SO STOP LYING AND TRYING TO COVER YOURSELF.

    Five Stars Isn't Enough for Eric Peterson! I would give him 100 stars if I could!…read more If you need a process server or private investigator who actually gets the job done, look no further than Eric Peterson. To put it into perspective: my attorney had previously hired a process server who spent an entire month trying--and failing--to locate and serve the defendant in my case. After four frustrating weeks of zero progress, Eric stepped in. He had the defendant located and served in less than 24 hours. This wasn't an easy task, either. The service was at a highly secure and challenging location--one that seemed impossible for others, but proved to be no challenge at all for Eric. The level of efficiency, speed, and sheer professionalism he brings to the table is unmatched. Beyond his incredible skills and hustle, Eric is just a genuinely great person to work with--communicative, trustworthy, and deeply dedicated. He took a high-stress situation and completely turned it around overnight. I cannot recommend Eric Peterson highly enough. If you want results instead of excuses, he is your guy! I will be sure to use him if ever needed down the road.

    I've worked with this Peterson Investigations quite often in a professional capacity, so I was…read morealready 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.

    Bosco is a great company to do business with. I started working with Bosco around 2012 while I was…read morewith a law office in Rancho Cucamonga. The office was using Bosco for process service. We had voluminous filings in various courthouses throughout CA. Many times the filings were last minute, contained errors, or may have been missing documents. Bosco went out of their way to correct and help us meet the filing deadlines. When we had a technical process service/filing question- Bosco knew the answer or would get it for us. I've continued to recommend Bosco to other attorney offices. Not just for process service, but for skip traces. Bosco found a defendant that had just moved houses and couldn't be located because all the leads went back to the house she had left. The defendant probably hadn't finished unpacking when Bosco discovered her new address and served her. There is absolutely no way we would have found the defendant without Bosco's quick and diligent work. Aside from their quality work- I love the fact their business is family owned and operated! Bosco as a company and within their staff excels at customer service, professionalism, and getting the job done!

    Update. To be clear, pursuant to instructions from the court…read moreclerk they were wrong. I heard from these folks after their review. I guess they have to check out your background before they do business with you although they had no problem with mine until I complained about their services. I can point out out great lawyers and judges in fact in their area with issues in their record. Everything in my review is true and correct so be careful about complaining about these folks they will try to come after you. I can deal with people making mistakes but not hen they will not own them. PS, they were willing to do the paperwork again but given their conduct we went elsewhere.
