Has…Helping You To Expose The Truth!

Quantum Investigations is the best Arizona private investigator for those relentlessly seeking answers…so that you can return to life as normal.

With 23 years of experience as a licensed PI, Jeff and his team of ex-military and ex-Phoenix PD have used their unique specialized skills to help attorneys, corporations, and distressed family members to find closure.

If we can’t get the answers you’re looking for, then nobody can.

We Specialize In These Private Detective Services

We Find Missing Persons, Asset Location, And More

Looking for someone who doesn’t want to be found?

If you’re searching for deadbeat parents, runaways, abductions, skips, assets, or simply former lovers, then no other agency comes close.

While other agencies are scanning old databases and doing basic social media searches (both of which you can do yourself), we use advanced police investigative tactics to narrow our search and find our missing person.

Unfortunately, this puts our team in unwelcoming environments and dangerous neighborhoods where we’re likely to get guns drawn on us…but the more difficult path is usually the only way to get real results for our clients.

We Offer Deep Due Diligence & Background Checks

Our Due Diligence service helps you to uncover, evaluate, and identify risk.

We help businesses, business partners and owners, attorneys, etc to gather relevant details, validate facts, confirm credibility, determine ownership or proof, and other necessary tasks to help you minimize your risk before doing a business deal or to build a case for court.

Our relentless process will either ease your suspicions or expose the facts necessary to help you to make an informed and educated decision. We’ve endorse major business deals here in Arizona, yet intervened with even more.

Undercover Physical Surveillance

TV makes surveillance look like the most relaxing job on the planet, but in reality it could mean death. Usually we’re required to put ourselves at risk to be in drug infests parts of the city that leave us vulnerable, or we post ourselves in dangerous positions to capture the best videos and photo evidence, while tracking someone who could potentially be life threatening if we’re discovered.

The risks are very real, but so are the results that we’re able to capture for our clients. We do stationary or mobile surveillance, on foot, in public buildings, on public transportation, or even across state lines. We have the man power and the network to coordinate multiple surveillance operations nationwide.

Criminal Defense Investigation

Hiring Quantum Investigations is the closest thing to hiring your own private police department. As former Phoenix PD we understand the investigation process, evidence to look for, statements confirm, and how to analyze a crime scene, take crime scene photos, interview witnesses, uncover witnesses who have not come forward, and more.

We add a second layer of protection from potentially devastate outcomes that can destroy your future or your client’s future. We bring military trained attention to detail to help reevaluate, examine, test, and/or confirm evidence that will be used against you in court. We bring hope and peace of mind in the worst of situations. 


Suspect Infidelity? We Are Cheating Spouse Specialists

Do you suspect infidelity in your relationship? Noticing warning signs that your partner maybe cheating on you? Are suspicious items, explanations, or disappearing acts getting out of control? If so, then call Quantum Investigations.

We help give you the peace of mind knowing that your husband or wife is being faithful, or we help give you the evidence needed to present in court in the unfortunate circumstance that it may become useful. Either way…there is only one way to know for certain.

Our team of licensed investigators will report every step taken and name and contact information of the person those steps are taken with. If you suspect a cheater in your relationship…then give us a call.

It’s better to know sooner than later.

Helping Families To Return To Life As Normal For Over 20 Years!

Here’s What Our Clients Are Saying…

I have to say this is the first time I have had hired a private investigator and I am totally impressed with Jeff and there team. I’m from Wyoming and within 18 hours Jeff had a GPS on a vehicle that I was looking for. Within 36 hours he was able to get possession of the vehicle. Jeff and his team are totally awesome to work with. If you need a Private Investigator this is the one to call hands down.

Jeff and his team were wonderful! They were thorough, professional, diligent and honest in the information I was seeking. Some aspects were challenging to get and they stuck with it until they found the answers that I was looking for. The information provided was comprehensive. I highly recommend this agency and I will use them in the future if I need them again. Thank you for all of your help and patience!!!

More than EXCEPTIONAL more than PROFESSIONAL!!!!!!
Quantum Investigations found the person I had been looking for with very little information I was able to give.

Investigator Jeff was upfront about the task, that it would be hard to find the person I was looking for but would do his best. After 2 weeks of research, he called me and asked some follow-up questions to help him pinpoint the person I was looking for. And to my surprise I got a call from Jeff the next week stating he found the person I was looking for, he even had pictures of the person. I highly recommend Quantum Investigations!

Thank you Investigator Jeff and Quantum Investigations, Your the BEST!!!!!
