Negative experience: When I walked in to the interview, there was an open bottle of liquor in the office and the end of a chummy conversation. The interview itself was executed professionally, but the final report on the investigation contained a number of errors. As the stakes for the investigation was quite high in my opinion (the safety of children), I was disappointed that the investigation was not thorough or logical. Whitestar group felt like a boys’ club to me. I truly hope their faulty investigation does not endanger anyone in the future. RESPONSE: Errors in the report are as follows: 1. the alleged concerning activity occured in Summer 2021, but it was reported by your investigator as Summer 2023. 2. an evidential communication was reported to have been a text by your investigator even though it was a facebook message. 3. the subject did NOT have a separate computer during the alleged activity aside from the district-issued device. 4. failure to investigate the claim that the subject's partner could have framed him and planted evidence of child sex abuse material on his computer. The partner's whereabouts were out of the country and the partner's location could have easily been verified with travel documents. I could go on with the shortcomings. Furthermore, I reported because the subject in question has access to many sacred children, including my own. I do believe that the children's safety continues to be at risk. I reported because I care deeply, and it is my duty. I cannot remove my review, because it is my experience, and I hope others will look elsewhere for thorough, thoughtful, responsible, accurate investigative help. True, I did not hire you, nor would I in the future.

We are responding to your review of our company. We just read your review and did some research since we are not generally the subject of a 1-star review. Firstly, this case occurred in 2023. It appears that you made a complaint to a school district regarding one of their teachers. Our company was hired as a neutral party to investigate the issue. I reviewed the report and found no errors. It sounds like you simply didn't like the outcome since the investigator did not find in your favor. It is disappointing that you feel obligated to give us a poor review and imply children were at risk. It was found that you were in corroboration with the respondent's ex-wife related to a child custody matter and utilized the school district and his employer in an attempt to disparage another party. It is not like you hired us and were unhappy with our work. We would ask you to kindly remove the review as it both unfair and untrue.

Fantastic experience: Excellent service! Paid them to find an old friend I lost contact with years ago. They did it in a flash! Amazing people. They kept me in the loop, didn’t waste time, and got started right away. I called another investigator service before them and the guy didn’t even take the time to take my information. Called these guys and they did the job and did it fast. High recommend them!

Fantastic experience: A huge shoutout to Jon Anderson and Leisha Tow for curating an exceptional BSIS guard card class. As a part of the first ever inaugural class, I wholeheartedly recommend it to anyone pursuing their BSIS guard card. Jon Anderson, with his extensive experience as an officer, provided insightful instruction, and despite it being his first class, I was thoroughly impressed – anticipating even better sessions as he becomes more familiar with the material. Leisha was instrumental on the backend, ensuring a seamless paperwork process and offering a warm, personable welcome. Overall, a fantastic experience – Guard Card Class, LiveScan, and Guard Card Registration all bundled at $199. If you're aiming to get it all done at once, I highly encourage you to sign up! -James

Fantastic experience: Recently, I accidentally lost my iPhone from the back pocket of my cycling jersey. Up until then, I'd never experienced misplacing my phone, and this incident made me realize how intertwined our lives are with these devices. I tried tracking it all over town but was constantly trailing the person who found it. Eventually, the next morning, I traced it to a temporary shelter where Whitestar Group provided site security. The Whitestar officer went above and beyond, being incredibly helpful, courteous, and professional in tracking down the individual who had found my phone. They truly exemplified five-star service!

Fantastic experience: I highly recommend Whitestar Group and have used them very successfully for many years in both investigative and personal executive security capacities. As a 30+ year private investigator and security consultant I both shared and received many referrals for services from Whitestar Group. Several of these included assistance to prominent celebrities, some of whom were notoriously difficult to please. Whitestar Group never failed to exceed both my clients and my expectations.

Stacy Spector 1 year ago

Fantastic experience: Whitestar is "white glove" service from the first call and consultation to the resolution of the investigation. During the last four years I have utilized Whitestar for multiple employee investigations and each time they were professional, discreet, and extremely thorough. What makes Whitestar unique is their expertise and knowledge of having former law enforcement officers as investigators. Even better, is that they understand the different contexts and constituents that impact an investigation. Whitestar gets the "whole picture" and the details right every time. I highly recommend their services.
