Joe Dalu President and Founder of PGI and Client Tiffany Thiessen discuss personal security

Wendy Hoffman

“Private Investigator Joe Dalu of Premier Group assisted me by unraveling my case, guiding me every step of the way with its progress and eventually positively identifying the suspects. He subsequently turned it over to law enforcement with a big bow on it so that they can pursue an arrest and prosecution for stealing my identity and over $100,000. He literally made the impossible possible and helped me regain my sanity. You saved my life, and I am forever grateful!”


Case Barnett Attorney

“Joseph Dalu is a tireless and skilled investigator. I have worked with Joseph and his firm on several cases and he impresses me every time. He is always accessible and his analysis and approach are unrivaled. We recently worked together on an indecent exposure trial in which his work proved instrumental in the not guilty verdict. I recommend him without reservation.”


Lee Sherman Esq

“I want to personally endorse Premier Group International and Principal, Joe Dalu. I and many other lawyers at Callahan Thompson Sherman & Caudill, have enjoyed a working relationship with Premier Group for several years during which they effectively and efficiently performed a wide range of investigative and security services for our firm and clients. Moreover, they repeatedly obtained consistent and positive results. Their professionalism, creativity and determination set them apart from what I have seen from other investigative companies. Additionally, I have also been impressed by their demeanor in court and overall expertise in their field.

In addition to their fine field work, they consistently provide timely and thorough reports targeting the specific information requested. In fact, I have been so impressed with their performance that I have, on many occasions, referred Premier Group to my colleagues and members of the insurance industry with nothing but positive feedback.”


Tiffani Thiessen

“I have used Premier Group International for all my security and investigative needs for the past 15 years. Joe Dalu is my go-to guy for all my red-carpet events and appearances. I trust him implicitly.”

Joe and his team are the VERY best at what they do. They handle your situation with such care and instill confidence and hope in whatever you may be going through… I recommend them to everyone! Thank you PGI for all your help. You guys rock.

Joe was recommended to me from a process server I used. I had a difficult time getting a judgement from a company I sued. He took the time and spoke with me on the phone, providing me with several detailed reports, which were very helpful. I could tell that he was truly interested in helping me and not just interested in payment. Highly recommend him any time you need some info that you are not able to obtain on your own.

Michelle M.

Wow! One call and papers were served in two hours. Entire process was easy, and Joe kept me in the loop the whole time. Cannot say enough about how grateful I am for the quick turnaround and professional service. With gratitude.

Mirelle P.

Joe did an excellent job of doing a thorough background check on a nanny candidate we had. He really took the time to ask the right questions so that we would be satisfied with his services. He went above and beyond and did some extra work to find out more information on this potential candidate. He talked us through the things we should be looking for. I highly recommend using Premier Group International.

Dee M.

Joe and his staff are wonderful. He handled the situation with tact, professionalism and kindness, which was much needed in my situation (custody issues). He has been flexible, very accommodating, and I highly recommend them to anyone.

Paul M.

You are an Angel!

It was an absolute pleasure having Joseph work on our case. He was extremely professional and polite who provided updates in a timely fashion. His positive and confident attitude helped to put us at ease through a very stressful and emotional time. I highly recommend Joseph to anyone who is looking for a competent and capable professional PI.

What a blessing you have performed. All I can say is: THANK YOU!

Premier Group International helps me with all my workers’ compensation claims investigations and SIU filings. In the 25 years I have been in claims and risk management, they have been the only firm that gets results timely with accuracy and without excessive spending. They are always available for rush assignments, holidays and go above and beyond with customer service. Even their office staff, Meg & Jillian has always been friendly, helpful and accommodating.

Wayne A.

I have worked with Mr. Dalu and his firm PGI for the past 5 years and have worked with Mr. Dalu and his staff daily as one of my service venders providing investigative services for liability insurance claims. Some of the investigations conducted were to prove or disprove potential fraud on the part of Claimant’s and/or Plaintiff’s against my clients.

Investigations would include background services, surveillances, review of claim files, and review of applicable police reports and obtain statements. I found that Mr. Dalu’s firm was always thorough and timely when conducting these investigations and as a result, often found and discovered facts and information that was not known to us during the filing of the claim. This information was at times instrumental in limiting our client’s exposure and thus reducing their liability.

PGI also interacts with Counsel and would often advise and discuss strategies in the litigation of such claims. I highly recommend Joseph Dalu and his Firm to anyone in need of their investigative services.

Steve S. & Family

My family and I were in search of our missing son, Chris. We filed a missing person’s report with the local police department where our son lived. Their investigation produced negative results in which they subsequently placed their investigation in abeyance deeming my son an official missing person without further or unusual circumstances. We reached out to Premier Group International and spoke to Private Investigators, Joe Dalu and Chris Heuberger. They not only took to heart this case and handled it as if were their own family member, they were professional, diligent, and meticulous, coupled with determination to find what happened to our son.

Through their investigative efforts, they not only discovered suspicious and unusual circumstances involving our son’s disappearance, they surmised based on physical and circumstantial evidence that our son was possibly murdered and were instrumental in having the case reopened. PGI orchestrated efforts with two different law enforcement agencies, in which an arrest was made for the murder of our son.

We can’t thank Joe and Chris enough for their hard work and compassion in finding the truth on what happened to our son making it possible for justice to be served.

Leah L.

It is with great pleasure and enthusiasm to endorse Premier Group International. I am a claims examiner for a Third Party Administrator and have worked with Premier Group for several years. During that time, they have distinguished themselves as the most conscientious investigators in the field. I have enormous respect for their pride in their work and the positive results that they are intent to provide us with and in fact produce.

After completion of an assignment, they personally hand deliver the finished product as they are aware of how important timeliness is in this business. If we have a rush request, which seems to be most of the time, they never hesitate and always accommodate us. Their creativity, resourcefulness and ability to achieve our requests with such efficiency continue to impress me. I have referred Premier Group International to other claims examiners and to other insurance companies. All seem to have the same experience dealing with Premier Group.

I urge you to carefully consider Premier Group International. They have been the best choice for all my investigative needs.
