Marshall-Investigative-Group

Have been with the Marshall Investigative Group for 3+ years now, and continue to be impressed with the direction of the company, and the leadership shown from management and colleagues for some time. 

Originally hired as a field investigator (after working surveillance for a much larger, much more rigid company), the differences became apparent almost immediately. Managers are more than willing to communicate and work with you regarding your schedule -- which is important for a job that often requires 10 hour days, and weekend assignments. They also provided me with the equipment and information necessary to be successful, and responses are generally prompt should a question arise in the field. 

Since moving into the office, I have enjoyed getting to know everyone as my schedule has become a more consistent 9-5, M-F.  Much like with fieldwork, co-workers have been willing to assist when needed, which contributes to a strong workplace culture and an enjoyable, colloquial environment.

With just under 100 employees, Marshall has already managed to make a nation-wide footprint (with employees in states from CA to NY) in a sector of criminal justice that seems to garner more attention by the day from our clients.

Marshall is the best place to work in the insurance investigation industry. The company offers a consistent workload, a diverse range of cases, and a growing list of great clients. Each case presents an opportunity to learn something new, enhance your skills, and become a better investigator.  

What sets Marshall apart is its results-driven approach—it's not just about pushing out cases and invoices but truly delivering quality investigations.  

The most challenging aspect of the job is staying organized. Adaptability and strong organizational skills are essential for success. While support and guidance are readily available, those who struggle with organization may find it difficult to keep up.  

The most rewarding part of the job is knowing that your work directly helps clients solve complex problems. You have access to all the necessary tools and resources and the freedom to apply your unique skill set.  

Ultimately, success here requires professionalism, accountability, and a strong work ethic—but for those who thrive in such an environment, Marshall is an outstanding place to build a career.  


The management team is continually grateful for your efforts in the field. They make you feel like a person. They do not micromanage you either. They make sure you get days off and don't get burned out. There will be times when you will put in some hours and travel is required but if you are in this profession you know that is part of the job. They don't berate you when you lose someone or make a mistake. Their report format is simple and it is very easy to upload video. Basically, if you know what you're doing and you prove yourself they will not bother you and yet they are always just a phone call away. They have taken all of the things you would expect of an employer and have perfected them. The benefits are good also and they just recently added dental and vision which is huge. I have nothing bad to say about this company. I could tell early on that I had struck gold with this company. If you work here you will not be disappointed.

Working at Marshall Investigative Group has been an incredible experience from the very start. This private investigative company not only offers exciting opportunities for professional growth but also fosters a strong sense of belonging for each employee. From the top down, the leadership is genuinely invested in our personal and professional development, always encouraging us to learn new skills and expand our knowledge.

What sets Marshall Investigative Group apart is how much they care about us as individuals. It’s rare to find a workplace that values its team members as much as they value the work itself. The environment is one of collaboration, support, and respect, where every employee is treated with kindness and given the resources to thrive.

If you’re looking for a place that offers both career advancement and a true sense of community, Marshall Investigative Group is the perfect fit. I’m proud to be part of such an amazing team that genuinely values both personal and professional growth!

A professional company and supportive work environment that encourages collaboration and innovation. If you want, plenty of hours, to include easily 20 hours of overtime per week. Excellent perks, working environment, plenty of help from other investigators and managers in each team. Working for four other companies I cannot express enough how happy I am to work for this company and the satisfaction of the appreciation you receive.

A typical day is 8 hours of work Monday through Friday with no weekends. Management is great to deal with and they are there to support you along the way. The company is nationwide, but the department is based in Dubuque and Park Ridge. Working in the office stills feels like you are working for a family owned company and their are events throughout the year that allow the agents to bond and interact with each other. 

There is so much opportunity at Marshall Investigative group to: learn new skills, grow personally and within the company, collaborate with different departments across the company, and work alongside like-minded individuals. The workload at Marshall Investigative Group is not for those uncomfortable with a fast-paced task, though the support to complete it all is readily available for you as an employee! 

Marshall is a great company to work for. As a field investigator, your get great support from your manager. There is flexibility in the days you get off, but be ready to work a ton of hours and do some serious driving. Pay is competitive for the industry. Managers are consistently ready to help you take your career in the direction you'd like. Overall it is a great company with good pay where you will be treated fairly.

Everyone at this company has treated me great. I enjoy coming into work everyday along with interacting with the staff. A normal surveillance day is a 10 hour day from 6 am to 4 pm with competitive wages and overtime possibilities.  A lot of work to be done at all times but, is very manageable. Overall, I would definitely recommend working for Marshall Investigative Group.

Was a great company up until release. They said they were okay with someone having kids but they get tired of working with you when you have a child with medical issues and try to blame it on something else.
