Customer Submitted Reviews

Great customer service. I made a request to Excell to find an old neighbor who I needed for a court case. Excell was very professional, they handled my case in a timely manner. I called them around 12:00pm in the afternoon and they sent me the requested data within 4 hours. They promised it would be the same day, although I was a little skeptical thinking they were over promising but they did come through with their word.

They provided me accurate information I am very pleased and I was successfully able to locate that person. They also made a follow up phone call a few days later to check on the quality of their work and they were able to provide me with even more feedback and suggestions. I definitely recommend their service.

Thank you Excell for all the efforts that you put forward to finding my cousin. Honestly when I first hired them we were very skeptical because we already went through four different private investigators to try to find my cousin which we haven't seen in about 10 years and since he had a lot of problems and was considered a Transient he was very difficult to find. All of the other investigation agencies kept giving us the runaround they will give us a bunch of documents with addresses that we already had. Since we wanted to do our search in Los Angeles area because of the tip that we had and we live in San Francisco it was easy for other investigator to play around with us. With Excel they made us feel very comfortable and they actually hit the streets to be able to eventually locate him. I want to thank you guys from the bottom up my heart and I wish your company all Success that they deserve.

Great interaction with John. My problem was solved in a timely manner. I needed family court papers to be served in Santa Fe Springs although I was located in NYC. John's people gave me information all through out the process and gave me a set price. My papers were served within 3 days of investigation. They did not charge me any surprise fees for extra work like most agencies do. I would highly recommend this place!

I had a great experience with this company. John helped me through till the end of my court case and made sure that all my paper work was served in time. My case was a bit difficult because I was in NY and needed to have papers served in LA. The distance did not stop them from communicating with me through the whole process. His guys were professional and courteous. If I ever need court papers to be served again, I will come to these guys for sure.

Excell served my legal documents in a timely manner and informed me as soon as as service was complete. In all my communications, they were professional and courteous. While I hope I won't require their service in the future, I would not hesitate to use them again if I do.

I had a very serious situation and I contacted Excel after finding them on Google. It was the first time I had hired a private investigator so I did not know what to expect. My general opinion about private investigators was kind of sketchy because I did not know how to evaluate them. But after looking and finding out the Excel was an accredited BBB business and I also checked out the reviews on Yelp I decided to try them out. I mean they had great customer service always from the jump they were able to give me a free consultation without any strings attached and they weren't really looking just to get my money they really wanted to give me advice and help me out. At the end of it I got the results that I needed and I was very happy and I would definitely refer them to anybody else as they have the integrity that most people are looking for in hiring a private investigator.

I was having some issues with theft and honesty at my place of business. Decided to bring in an outside resource to investigate. Nizar and his team helped get to the bottom of it within a couple of days. Would recommend for everyone. Their rates aren't bad either.

I live in Florida and I needed an investigator out in California, it was difficult to locate someone honest reliable and trustworthy with me not being from the area. I called around to several people but here I felt most comfortable. He was clear and communicative in order for me to maintain my comfort and security throughout the investigation. The case in which I needed required someone very diligent and I have not met anybody more diligent than him. I highly recommend him over anybody else, if you need someone honest, trustworthy, faithful and committed this is your man. I also am happy now I have an investigator who I can call anytime, who is reliable and not just out to make money, whenever I need to watch my clients out in California and see if they are robbing me or not.

Thank you

Having noticed excessive amounts of money showing up missing from a clients retail store I encouraged her to hire Excell to get to the bottom of the situation. Nizar worked in an efficient and sophisticated way to get to the bottom of the issue producing very surprising results that saved my client's business thousands and thousands of dollars. I've also hired Excell in my capacity as an attorney to help with investigations on behalf of clients and to uncover the truth in family matters in order to protect my clients interest and likewise save them money. I'm so happy to continue the collaborative relationship with Nizar and his team and I don't hesitate in giving him my highest recommendation.

I used them through my attorney to conduct tasks beyond what my previous investigator could do. It seems they just have more experience and sources that your average investigator has.

After meeting with them and explaining our situation they were able to get to work asap. Within no time Excell got to the bottom of it. Definitely check out their services!!!

In my search for a PI Excell was one of many I spoke with and John Milbes who right away was very pleasant and easy to talk to in addition willing to help and offered to match any quote I received. My circumstances changed and I thought I no longer needed services and then changed again to needing something very difficult to get. I called John and before I knew it was on the phone with someone almost impossible to reach, this was a breakthrough for my case. He did this for me without being officially hired and was just as happy he was able to help as I was for the help. This tells me it's not about the money and that is rare in this field at least as far as I could tell from calling dozens of companies. He was quick, accurate and because of his actions I secured my case so that the opposing party could not have a chance in winning! Now that is amazing! My heart felt gratitude and admiration for your skillful help. If your looking for a PI it's because something is very important to you and it's huge if you can relax and know your not being taken advantage of and they are doing their best for you, you can't ask for anymore than that. Thanks John from the bottom of my heart thank you!

If you are looking for a great PRIVATE INVESTIGATOR IN CALIFORNIA, look no further. I hired Excell for a surveillance case in regards to my babysitter. They were able to set up a hidden camera in my home and we were able to watch her every move. I got the proof i needed to fire her and now the peace of mind i deserve when it comes to someone responsible watching my child.

I called several private investigators in both los angeles and orange county. I priced many of them out, and yes, some might have been cheaper but after speaking with Excell i felt that they were extremely knowledgeable and you know the deal "you get what you pay for" so i went with them. I was very pleased with the way your company handled my case. You knew the exact steps i needed to take and the exact way to do it. The private investigator at Excell was very discreet and confidential which was a huge plus for me. Thanks Excell for giving me the closure i needed.

Worked with John on a very difficult private investigation case. These guys are truly experts and I was able to get what I needed quickly and cost effectively. They explained the process of what they were doing each step of the way and kept me updated constantly regarding the status of my case. Honestly if your looking for a professional and hard working PI, I wouldn't go anywhere else but Excell.

Best Investigators in CA!!!! They did the job super fast. I don't have nothing bad to say. They keep you updated and fast! Loved them!!!!!!

Susie C., Maywood, CA

If your looking for a top notch private investigator at a reasonable price, you will not find the level of service at an affordable price like this place anywhere. Trust me i have used several other Investigators, now i realize with investigations you get what you pay for. Call Excell

Kyla C., Compton, CA

John is awesome... Before I contacted him, I contacted another process server and they couldn't get my defendant served in three weeks! I decided i didn't have much time and i should try my luck with another process server. So, I contacted Excell Investigation Services in Los Angeles after finding terrific reviews on the web and yelp about them. They were able to serve my party the very next day! I am so excited to have gotten the service over with in time for my court date. I couldn't be happier with the service and dedication that Excell provided. John contacted me with updates (even in the day and a half it took to serve the person) and was very informative about the whole process. Hopefully I never have to sue someone again, but if I need anything like this again, I would call John and Excell Investigations in a heartbeat. They are terrific and got the job done immediately! And John is really cool and smart. I would totally call them if you need this type of service.

Diego G., Westchester, Los Angeles, CA

Communicating and dealing with Excell Investigations was both professional and successful. All the staff from John to the others treated me as a family member and all were more then happy to help me with my case. I never regret calling them or going down to their office in Downey which isn't too far from my home. The staff are great, and the investigation services they provide are far more then excellent !

Mohammed S., Oceanside, CA

A little bit ago I was in the middle of a very nasty divorce and needed a process server to serve my ex wife. She did everything in her power to hide and avoid facing me in court. I called Excell Investigations and spoke to Linda. She was very professional, caring and understanding. The next day i drove down to their offices in Downey, just a skip hop and a jump away from my office in Downtown Los Angeles. Hopefully, I won't be in need of process service again, but if I do, I will definitely use the good people at Excell Investigations!! Kudos
