Yves M.

Jeff and his team provided private investigation services for me in a child custody case. They were extremely thorough, professional and detailed, but most of all, Jeff works with a very high level of integrity. I would highly recommend him and his team in any situation.

Stephanie M.

Anyone that's worked with Jeff quickly realizes that he's an expert in loss prevention and retail safety. From a rather random connection he and I made initially, he became a trusted advisor to Infoglide Software in our approach to the retail space. Jeff was very enthusiastic about sharing his expertise, and we felt very fortunate when he wrote guest posts for our IdentityResolutionDaily.com blog. If you're looking for expert help with LP, you could do no better than Jeff!

Bob B.

After working with Jeff on a surveillance for 8 hours I became well aware of his professionalism. The assignment was his and I worked alongside. Jeff made sure the client's best interest was always the most important factor in the case. I found him to be pleasant and willing to listen to all suggestions though he realized that the final decision was his. Though he expected me to get the job done he did it in a way that left you feeling you were a part of something. It was a pleasure to work with Jeff and I hope that I can work with him again in the near future.

Frank D.

Jeff is a true visionary in the fields of Loss Prevention and Security. I have worked with him on several projects spanning a period of several years. He is a strong personality with excellent results-oriented skills. I proudly recommend him!
