About Us

Over the past two decades, Jeff Penrod as become a leading Private Investigator in Phoneix AZ. The page will give you a background of how this all started.

Jeff first got a taste of the private investigation industry during his years in the military. After serving in the military and by having a service background, he was able to land a job in law enforcement by working for the Phoenix police department. After working there for 5 years and seeing how the department didn’t have the resources or manpower to help out good families who still had unanswered questions, he decided to become a private investigator to help those families who found themselves in similar desperate situations.

The Path To The Industry

Approximately 23 years ago he decided to join some friends who retired from the police department and took him under their wing. They mentored him on how to magnify the skills he learned in the force and apply them to work on everything from criminal defense cases to asset repos to catching bail jumpers.

 He isn’t afraid to deal with anybody to get the job done. He won’t be intimidated, and he won’t be stopped.

Persistence is what absolutely separates him from the many others who are out there. And after learning from some of the best in the industry, Jeff decided to venture off on his own.

 In early 2000, he started what you now know as Quantum Investigations.
