Unum Investigations, LLC is an elite and highly specialized boutique private investigations practice focused on cultivating a limited amount of strong client partnerships, and providing that select clientele with truly custom solutions and individualized attention. “Unum” is Latin, signifying “one,” expressing my one-on-one commitment to a very select clientele.


My name is Mitchel J. Hoffman, proud owner of Unum Investigations. I work directly with my clients and intentionally have no employees or lesser experienced "field investigators" that I utilize. I will also never delegate your important matters out to other investigative subcontractors unless this has been transparently discussed and mutually agreed upon in advance.

Meet Mitchel J. Hoffman, MS, CFE - Private Investigator

I am highly experienced and educated in the investigative industry and am extremely passionate about my work in private investigation. Over a span of more than 20 years in both the private and public sectors, I have conducted thousands of private investigations on the behalf of international insurance carriers, top-tier law firms, Fortune 500 corporations, government agencies, and high-net-worth individuals encompassing both criminal and civil related matters. I have been employed by global investigative companies in the private sector with yearly revenues exceeding hundreds of millions of dollars.


I have been involved with public and private sector investigations in several states, including New York, Connecticut, New Jersey, Rhode Island, and Massachusetts along with Wyoming and Colorado. These investigations (and related interviews and interrogations) have consisted of sensitive and intricate matters involving workers’ compensation and disability, a multitude of delicate corporate internally focused matters, liability investigations, theft/fraud occurrences, domestic violence related situations, complex drug investigations and interviews, cultivation and usage of informants, and undercover work. I have also participated in countless court and administrative hearings pertaining to these investigations.

I have served active duty in the United States Air Force (USAF) in both Military Police/Security Forces and Air Force Office of Special Investigations roles. Along with graduating first in my class of the USAF Security Forces/Military Police Academy, my military roles consisted of the completion of multiple expert-led formal interrogation and investigative related courses. I completed my active-duty time in the military with an honorable discharge. I also have two separate graduate degrees: a Master of Science in Criminal Justice Administration and a Master of Arts in History. I also possess a Litigation Paralegal Certificate and have also obtained the highly coveted investigative industry related Certified Fraud Examiner designation. I have most recently earned the honor of becoming a board certified Professional Certified Investigator, obtained via an extremely rigorous and lengthy selection, testing, and review process. Completing my Certified Forensic Interviewer designation, and also earning a separate certificate in Employee Relations and Investigations from Cornell University are both further achievements that I am proud of.



I am also licensed, insured, and bonded in all three states that I operate in.

The Unum Difference

Personalized Private Investigative Services in NY, CT, & NJ


If you’re looking to hire a private investigator, you need to know who you’re working with. At Unum Investigations, you can trust that I will be the one handling your file directly. My commitment to this one-on-one approach is central to the Unum difference and how I intentionally operate in stark contrast to most investigations firms.

Prioritizing Transparency

Each state has its own private investigator licensing requirements, regulations, and steps to complete before issuing a private investigator license to an individual or business entity. Consequently, most private investigators and investigations companies are just licensed in one state and claim they are the “biggest” and have “national coverage” when, really, they’re just using subcontracted or part-time licensed private investigators to perform work in the various other states that they are not licensed in. As the client, you may have no idea that the work you hired the local firm to perform in other states is possibly being done by an entity that has no relationship or loyalty to you.


Unum works differently. Unless transparently discussed and mutually agreed upon with a client, I will not subcontract any aspect of my clientele's needs to another investigative firm or service provider.

A Singular Investigative Partner

It is common practice that hired “apprentices”, “field investigators” or “employees” work under the owner’s main license umbrella. These “apprentices” are not individually licensed private investigators, could be earning low wages and may have zero experience, formal training, education, or knowledge of the tradecraft of surveillance and investigative techniques. Drawing on my past direct observations and experience, I can assure you that these “apprentices” typically don’t care about what happens with your file and are not truly invested in providing you with the answers and evidence you seek. Is that who you want out in the field, working your file? I will ALWAYS work your file directly. I do not have any other “investigators”, “apprentices”, or employees working for me. This also affords me the ability to handle the most extreme private and sensitive matters on behalf of my clients while ensuring their trust and confidence is well guarded


I believe a client should directly receive the value and dedication that they are paying for.

Specialized Investigative Services

Many investigative companies have names that end with misleading “Global”, “Group”, or “Nationwide” extensions. These companies claim that they do everything and that they do it everywhere. They want to cast a wide net to reel in clientele and appear that there is nothing that they aren’t capable of. If you hire a private investigations firm to handle all of these vastly different specialized fields, chances are, the work may be subcontracted out.


I serve a very niche clientele and their high-end needs. I have no interest in purporting to be a “specialist” and “expert” in services that I do not directly provide myself. I typically do not take on any other type of work outside of my listed services. However, if you feel that you have any other issue or type of file that you’d like my assistance with, feel free to contact me and we will discuss if I may be of service.
