    International Oil Services Firm
  • “Frizell Group has been an indispensable investigative asset. The owner, David Frizell is a relentless and tenacious investigator who has the best interview skills I have ever seen. In my 25 years in Federal Law Enforcement, I have never witnessed as skilled an interrogator as David. He has solved numerous cases with little or no actual evidence. As significant as his investigative skills are, David’s unwavering integrity and absolute resolve to be truthful and honest is his defining asset. I strongly recommend Frizell Group to anyone needing a top-notch investigative firm that can be trusted and provide you with outstanding results.”
