Hiring Curtis Moore was the best decision I could have made regarding my search quest. I researched many professional, experienced Private Investigators, both online and locally, and chose Curtis as the best possible option from the 23 contenders. Now that I've experienced: his superior work ethic, his valuable insight in discerning my needs, his thoughtful follow-up call the day after I'd processed his investigation results and his incredibly prompt response-I have but one conclusion. *Curtis Moore walks on water.* This is your choice, People. It is impossible that so many glowing reviews from his clients can't lead you to desiring the same peace of mind and spirit which he will offer you. I'm incredibly grateful to have crossed paths with him via this site. Believing for the best for all who enlist his services as well. Thank you so much, Curtis. You rock!

Curtis is the most honest person I've ever met. Once he got the details of the project, he called me and offered me free (FREE) advice. He said that I don't need to pay anybody and explained me in detail the steps to be taken. He also declined my offering to pay him! If you need a private investigator, hire him. Without doubt. He is on your side and will make everything possible to help you. I can't thank him enough!

This was my first time using a private investigator, and I was very pleasantly surprised. I would certainly recommend him to anyone seeking information. Thank you for the help you provided!

Samuel Bowden did some investigative work for me in Baltimore, MD that took about a month to complete. He was very professional in his demeanor and was always punctual with meetings and deadlines. He was very detailed in the feedback he provided about the results of the investigation. If I had additional questions and/or required more information, Samuel was more than willing to do accommodate me. The only recommendation I would make is that Samuel continue to provide great service to his clients.

Mr Bowden appeared to know what he was doing and got a lot of information for my family. I was able to have constant contact with the investigator about each step. He also explained and assisted with addressing the issue and the best way to address the issue. He was professional and had excellent work quality and had great punctuality in getting the business done. I will use him again and recommend him to other people..

For the last two years I been confused about if infidelity was destroying my marriage. Was not sure how I was going to figure it out. Well with the tech savviness of this corporation I was able to put my thoughts to rest through investigation and I.T. They were on time, prompt and the only problem I had was debating if I wanted the extra expense but I'm glad with the end resolve.

I thought I filled this out before Thumbtack. Stop losing my reviews. Anyways Eagle Eyes, Andre is a total professional. I had clients who I knew stole my money and I needed his help. He was up before 6 am getting video of them and doing comprehensive reports and his rates are very good. Yes I will and am using him again. Thanks thumbtack for having this site. It really helped me find a great Private Investigor when I needed one quick. I definitely give Andre 5 stars.

Eagle Eye Investigations services are first rate. Their investigators are well prepared and professional. I really appreciate Andre H. assistance as he was able to acquire valuable evidence necessary for an upcoming court case. He was also able to successfully locate and process serve someone that had been avoiding being served for months. I recommend Eagle Eye Investigations without any reservations.

My application for my divorce was denied and had to re-file it this year and I was feeling so frustrated about it already. I contacted Zicherheit LLC and I am so grateful that I made a great decision to hire them. In less than a month they were able to locate my ex and served him the summons. Thank you so much for your dedication and professionalism in helping me out in this stressful time. Keep up the good work!

Mr. Zicherheit was prompt and very professional. I wish he had had more prior Power of Attorney customers so he could offer more perspective to us on what we were doing. But, that's not what he was there for.

PROFESSIONALS TO THE MAX!!!! Bill not only gave me the confidence that he could execute this mission without any problems, but he also gave my client the information he was looking for. The client was more than happy for all bill did. As an Investigator and a business owner, I highly recommend Bill and Coast Investigations to anyone. They are true professionals and that you don't find everywhere. Thanks Roger

I was very pleased with the service of private server that William Robb provided for me. He said he would be able to complete it with one try and he did just that. He chose the right time of the day on a holiday weekend and he had it planned so well and I do not think he could have planned it any better. Ricardo

I have nothing bad to say about my experience. From the initial phone call through the receipt of the affidavit, STW Research & Investigation Services was very professional. Not only did Harry explain thoroughly how the process works, but he also worked with my schedule, and reimbursed me with no questions after I realized that I only needed to serve one party instead of two.

Harry Ponack was wonderful. I couldn't believe how quickly he made the service attempt, how reasonable the fee was, and how quickly I received his Affidavit of Service. I wouldn't have to think twice about whether to use STW Research again in the future.

Working with Alex was such a pleasant experience as he is very kind. Hiring private detectives can sometimes be a hit or miss, but I have absolutely no regrets. Alex is very intelligent, knows what he is doing, and more than exceeded my expectations. His level of professionalism is rare gem as he is attentive to the needs of the client, efficient in the amount of time given for a project, meets the deadlines, and innovative. He is very good at what he does and does not like to bring anything less than satisfactory to the table. Alex is bilingual in Spanish as well, which was a tremendous asset! I will definitely be working with Alex again.

Mr. Vasquez really cares about his clients and he demonstrated this through his work with my case. I needed information and evidence regarding a child custody issue and he provided very thorough information, evidence, and documentation. He provided advice and helped walk me through the process and the matter overall. His keen attention to detail and empathy toward my case helped me relax and trust he would get the job done. I highly recommend Mr. Vasquez for any investigative work.

I knew for sure something was going on with my husband and one of his coworkers. It was hard for me to prove it outright since they both had to attended the same work functions, same clients, same office. Of course they’d be everywhere together. But Discreet Investigation Solutions was able to prove what I’d known in a short amount of time. They were able to attend these “work functions” with little notice and more affordable than I thought. I’m no longer worried me and my 2 kids will be living in a studio apartment. Thanks you guys so much!!!!
