Peter helped me gain 50% custody of my kids during my divorce…read more With his surveillance, professionalism, and keen instincts he gathered enough evidence to prove my ex-wife was doing a bunch of wrong things, showing she is a poor mother and she was alienating me from my kids while she was abandoning them. This also helped reduce her alimony by proving that she was not working, when she claimed to the court she was working full-time. With Peter's help, she finally got what she deserved. Divorce is screwed up for the man if the ex-wife is crazy and makes crazy claims, the man is automatically put at a disadvantage and has to gather evidence and prove he is actually a good dad. The divorce court system is screwed up, but thanks to Peter we proved her wrong.

Anna is a TRUE gem! When you hire a private investigator,…read moreyou think about justice, fair play, due process and someone who is authoritative. But Anna kicks ass at the integrity, empathy and honesty of the your situation. Because Face it. If it comes to you needing a private investigator, it's taken you on something of an extremely emotional ride to get there! She honors that, she honors you and she's down to Make. It. Happen. And oh, she will! We got into business within the first minute of the call. By the way- she came up first as recommended despite a different county and called me on same day. She's AMAZING!!! Go with Anna. My family are more than grateful and happy we found her!!

I hired Anna to find a long-lost friend from grad school (1974) I'd not heard a word from since…read more1987. I'd searched the net for ten years trying to find out something, but he was totally "off the grid." It took several months, but Anna found out that my friend had died in 2001 and was buried in Gainsville, FL. She could have stopped there, but she went above and beyond by finding my friend's sister (whom I didn't even know he had.) She contacted the sister and learned that the sister would be happy to speak with me. I called the sister and we spoke for two hours. It was wonderful to finally get the closure that had eluded me for so long. If you have PI work, call Anna. Done and done.

He's 150% professional, courteous and trustworthy. I originally hired a different company that I found randomly online a couple of years ago. I was ripped off and walked away not trusting any private investigator. Soon after, I had no choice...I had to have my ex served for contempt of court AGAIN. I used Yelp that time and found Rob and this company. I reluctantly hired him at that time for the first time, and it was the best decision I ever made. Thank you from the bottom of my heart, Rob. You are my hero! I thank God all the time for your help.

Got exactly what I needed and gave me a great recommendation on wine! Thank you guys for your work.

Not only were they very professional, they went above and beyond to get this job done. To give you an idea, they went to the defendants house 6 times to serve her court papers. On one occasion the boyfriend threatened to shoot them, and instead of calling it a wrap, the team followed them as they left their house. They followed her to a store and successfully served her in the parking lot. Thank you so much Erik, Mark, and the rest of the team.

"Property Management's Best Friend in Sacramento's Homeless…read moreChallenge" I am a Property Manager at a small professional building on Watt Ave that has a constant presence of homeless people camping out in front, which is a problem because of all the trash that is left behind or some of them may be in need of mental health assistance and scare tenants. Reluctantly, I hired Horizon Protection Security because I did not want to add more expense to my operation, but it turned out to be one of the best decisions made! Brent Shaw, who is the operator of the business, has been very easy to work with and will take photos or give me a periodic report of findings. One of the most important parts of his job is making sure the automatic gate is closed at night and he has given me a notice a week before any of the tenants even realized what was happening and I was able to get the repairs done! Whew! [Less stressful phone calls!] The tenants have been very happy and I know Brent treats the homeless people with dignity and politely asks them to move because, homeless people are people too. Thank You Brent!!
