William was a big help throughout my case. He and Christopher communicated in a timely manner. William was very direct and informative in his responses which gave me confidence that the job would get done. They are a bit on the pricier side, but in my experience it was definitely worth it. The skip tracing was quick and effective, and once everything was ready, William followed through exactly as promised when it came to serving the defendant. Overall, I have no regrets choosing their service and would definitely recommend them to anyone who needs a reliable and professional process server. read more

We used William to serve a small claims summons after the sheriff failed to do so, and he got the job done extremely quickly. I cannot recommend him enough--he was extremely professional, communicative, fairly priced, and clearly very dedicated to his work. In fact, the defendant almost ran over him with her car when he was serving the summons and he stuck it out and got the job done. Hire him, you won't regret it. read more

I am on the west coast and needed to have a service done in the Chicago area. I called and spoke to William about my needs and perhaps some challenges finding the individual to serve. William was very professional, offered some different services if the individual was elusive and made it clear I'd called the right guy. Despite the individual's attempts to cover his tracks and move around, the connection was made. I received progress reports as things happened and although I hope to not need services like this in the future, I know who I'll call. read more

Carlson Investigations is the best, bar none! William is truly a master of his craft. Diligent, goes above and beyond, and works hard in finding and serving elusive and difficult parties.

He is incredibly knowledgeable, highly professional, trustworthy, sensitive to timing, efficient, offers fair pricing, and fantastic with communications. Highly Recommended! read more

I couldn't get my tenant served for months because he kept dodging other process servers but then I hired William and he got inventive and served my tenant in a day. Many many sleepless nights are now behind me since my what seemed to be stagnant case can finally move forward. Thank you sooo much Carlson Investigations Inc!!! I will forever be grateful . read more

Mr. Carlson was quick, prompt, and effective. Would recommend to anyone in need of private detective.

We don't live in Chicago and were uncertain about how to serve a defendant. We've never done this before. Our attorney suggested that we use a NAPPS-certified process server (napps.org) and I crossed those names with the ones rated highly on Google and Yelp. It worked! Mr. Carlson promptly returned our email inquiry and when we called for a minor issue he personally answered the phone and immediately addressed it. This is a family-run business, exactly who you need when you are in a new and stressful situation - as we were. We paid a little more than we expected, but it was still quite reasonable...and for the service it was a bargain! Highly recommended. read more

We use Carlson Investigations for everything at our firm. He is professional, timely, detailed and makes sure everything is done correctly the first time. He has great communication and always keeps you up to date as to what is going on. He also has incredible prices. Cannot recommend enough! read more

He deserves stars beyond 5. Thanks for an awesome job.......Ron W. Chicago Properties Owner. read more

Courteous and professional. After submitting an inquiry during the night, Will Carlson called me himself (first thing in the morning!) and recommended a course of action. Though he couldn't help in my specific situation, he gave great advice and went well beyond my expectations. Fantastic customer service. If I have the need to use investigation services again, I know who to call! John read more

Will is best in class and I highly recommend him! read more

This company did an excellent job addressing my summons. I had used the Sherriff's office and they were unable to track down the company for me. The Sherriff's office did what they could, but I was left with no summons service. William called me on site at the company and gave me full details about what he found. Further, he looked up the CEO's home address, and immediately was able to service him there. In a couple hours, my problem was solved. Throughout the process he kept me informed and I was fully aware of all the details. This issue has been a distraction from my business. It is great to have someone to help who minimized the stress and time required to get this job done! Thanks Carlson Investigation!!! read more

This guy will go the extra mile for you! My Dad needed to serve his wife divorce paperwork after she was dodging service from the sheriff for a couple of weeks. He came up with well-strategized and creative plans, and was able to get her served very quickly. This was not an easy case and he made it happen. Will keeps you informed of his progress each day that he works on your case and takes pride in doing a thorough job. Honestly, if we were to hire anyone for service again, it would be Will hands down. Thanks, Will! read more

I normally dont write reviews but I feel compelled to write to warn other attorneys about this company. We paid $300 for rush service. After almost a week the person still had not been served. I called to inquire about the status and was told, the process went out the house this morning but there was no answer. The house they had allegedly went to was burned down. So clearly we were mislead when we were told they had been to the house that morning. We got the address of the hotel where the family was staying and gave to Carlson. Immediately we got another bill for $300. I stated we would pay but the person would need to be served first. Carlson told me we have made contact with the person and will have them served dont worry. Of course, they have not been served. Even though we provided the name and room number of the hotel where they were staying. This company is a rip off. Please avoid them at all cost. You are wasting your client's money. read more

Incompetent, unfriendly and not customer service oriented. Don't use unless you want to lse time and money. They served the defendant and they told me they would file the affidavit with the clerk but they did not and I wasted a month and had to pay another server. read more

Will Kicks Total Butt! I contacted Carlson Investigations to have my ex served in Cook County. I didn't feel like dealing with the Cook County Sheriff Dept. Will was extremely professional, very communicative, and served my ex within two days. I will definitely be using Will the next time I need to serve someone. Highly Recommend!!! read more

Will went above and beyond our office's expectations! He was efficient, professional, and savvy. Our case was a bit difficult to serve, but Will ended up staking out in front of the house until he was able to serve him. I would definitely recommend Carlson Investigations. read more

I found Carlson Investigations through the National Association of Professional Process Servers website.

If I could give 10 stars I would, and still say I wish I could give more. I had unsuccessful attempts from another process serving company my attorney recommended and used regularly, as well as several attempts from the sheriffs office on service of legal documents. I turned to Yelp to find the right person myself, and honestly hit the jackpot. In less than a week, William was able to accomplish what we had been trying to do for close to two months. He took the situation and job personally and made us feel like it was his top priority to get these people that were clearly evading service served...and did it with ease! Constant communication, the highest attention to detail, and the most important...effective and efficient plan of action. I cannot recommend William and his team enough. I can honestly say, if you are looking for services this company offers - you will not be disappointed. This is a top notch customer focused company. My only regret is that I didn't find them sooner. From one small business to another, Thank you Carlson Investigations for all that you did for us! read more

Will Carlson was excellent to work with! He assisted me with a skip trace and process service.

Will is an excellent communicator, easy to work with and has reasonable prices for his services. I highly recommend Will! read more
