There’s a specific exhaustion that comes from sitting with a suspicion you can’t prove. You’ve been turning it over for weeks or months. You’ve looked for answers on your own and come up empty. That’s exactly the point where professional private investigation services make the differencenot because we have magic tools, but because we know what to look for, how to document it, and how to gather it in a form that actually holds up when it matters.
Goodyear covers 191 square miles across some of the fastest-growing neighborhoods in Maricopa County. Whether you’re dealing with a custody dispute heading to family court, questioning a new business partner, or handling something closer to home, what you need is documented, factual information. Not a gut feeling. Not a suspicion. Evidence.
We’ve worked across Goodyear for over two decadesfrom the master-planned communities in the south to the neighborhoods near Luke Air Force Base in the north. That local experience means we understand the geography, the court systems, and what it takes to gather evidence that actually matters in Maricopa County Superior Court.
We founded Quantum Investigations because we saw a gap that needed filling. Our founder, Jeff Penrod, spent five years with the Phoenix Police Department before launching this agency. He didn’t leave law enforcement because he was done with the work. He left because he kept watching families with legitimate, urgent questions get told there was nothing the department could do.
That’s the foundation we built on. Not a business opportunity. A real need.
For over 23 years, we’ve served Goodyear residents and businesses across Maricopa County. We hold a current Arizona Department of Public Safety license, maintain two physical offices in the Phoenix metro area, and have built our reputation on honest assessments, professional documentation, and results that hold up in court. Before you ever pay a dollar, you’ll know exactly what we can and can’t do.
The first step is a consultationand it’s a real one. You share what’s going on, what you know, what you suspect, and what outcome you’re hoping for. We’ll tell you directly what’s realistic, what isn’t, and what the investigation would actually involve. If your situation doesn’t call for a private investigator, we’ll tell you that too. No pressure, no pitch.
From there, if it makes sense to move forward, we plan the investigation around your specific circumstances. For surveillance cases in Goodyear, that means accounting for the city’s geographythe distance between communities like Estrella Mountain Ranch and the commercial corridors along I-10 and Loop 303, the behavioral patterns of subjects during the extreme summer heat when outdoor activity drops off, and the tight social networks inside master-planned communities where discretion is essential.
As the case progresses, you stay informed. When the investigation is complete, you receive a documented reportorganized, clear, and prepared to meet the evidentiary standards of Maricopa County Superior Court if that’s where your case is headed. The goal isn’t just to gather information. It’s to gather information you can actually use.

Arizona is a one-party consent state, and licensed private investigators can conduct video surveillance in public spaces without notification. Every investigation we conduct follows Arizona lawwhich means the evidence gathered is clean, documented, and admissible. That matters more than most people realize until they’re sitting in a courtroom.
A licensed private investigator in Arizona can conduct surveillance in any public or semi-public space, document a subject’s activities, locate missing persons, run background checks, perform asset searches, and gather evidence that can be used in civil or criminal proceedings. What we cannot do is trespass on private property, access protected financial or medical records without authorization, intercept private communications without consent, or impersonate law enforcement.
Arizona is a one-party consent state for audio recording, which means a conversation can be recorded if at least one party to that conversation consents. For video surveillance, we can record in any location where a person does not have a reasonable expectation of privacypublic streets, parking lots, commercial areas, and similar spaces. In Goodyear, that covers a significant range of environments, from the retail corridors along Estrella Parkway to the open spaces near Estrella Mountain Regional Park. The key is that the investigator conducting the work holds a valid AZDPS license and operates within the legal frameworkbecause evidence gathered outside those boundaries won’t hold up in Maricopa County Superior Court.
Private investigator rates in Arizona typically run between $85 and $150 per hour depending on the complexity of the case, the experience of the investigator, and the type of work involved. For straightforward surveillance cases, total costs often fall in the $500 to $2,000 range. More involved investigationsmulti-day surveillance, missing persons cases, asset searches tied to divorce proceedingscan run $3,000 to $5,000 or more depending on what the case requires.
We work on a retainer basis. You fund the investigation upfront against an estimated number of hours, and you receive an accounting of how that time was used. Before any money changes hands, you’ll get an honest assessment of what your case realistically involves and what it’s likely to cost. That transparency matters, especially for Goodyear residents whose cases may be tied to Maricopa County family court proceedings where the stakesa custody arrangement, a divorce settlement, a business disputeare significant enough that cutting corners on the investigation doesn’t make financial sense.
Yesand this is one of the most common reasons Goodyear residents reach out. If you believe the other parent is violating a custody agreement, exposing your child to unsafe conditions, or misrepresenting their lifestyle to the court, a private investigator can document what’s actually happening through surveillance, background checks, and activity reports.
The critical factor in a Maricopa County custody case is that the evidence needs to meet court standards. A video clip from your own phone, a screenshot from social media, or a neighbor’s verbal account may not carry the weight you need in front of a judge. Documentation gathered by a licensed private investigatorwith a clear chain of custody, professional reporting, and an investigator who can testify to what was observedis a different category of evidence entirely. Our founder’s background with the Phoenix Police Department means we understand exactly how Maricopa County courts evaluate investigative evidence, and every custody case we handle is documented with that standard in mind from day one.
Not if the investigation is handled correctly. We treat every case with strict confidentialitythe subject of your investigation will not know surveillance is underway, and your identity as the client is protected throughout the process.
This matters especially in Goodyear’s master-planned communities. In neighborhoods like Palm Valley, PebbleCreek, and Estrella Mountain Ranch, residents tend to know each other. HOA events, shared amenities, and close-knit social networks mean that word travels. A poorly handled investigationor an attempt to do it yourselfcan surface quickly and either alert the subject or damage your standing in a legal proceeding. We’re trained to conduct surveillance without detection, to blend into the environments we’re working in, and to avoid any action that could compromise the case or your privacy. From the initial phone call to the final report, your situation stays between you and the investigator handling your case.
That’s one of the most common things clients say when they first call. And it’s one of the main reasons we exist.
Law enforcement operates under resource constraints, jurisdictional limits, and legal thresholds that don’t always align with what families actually need. If your adult child is missing but left voluntarily, police may classify it as a non-case. If you suspect insurance fraud or a custody violation, it may not rise to the level of criminal investigation. If you’re dealing with a civil mattera business dispute, an asset concealment in a divorcelaw enforcement simply isn’t the right tool. We work outside those constraints. There’s no case backlog, no threshold of criminal severity required, and no bureaucratic process standing between your question and an investigation. Goodyear’s own police departmentlike every municipal department managing a rapidly growing cityhas finite resources. When those resources don’t reach your situation, a licensed private detective agency is the appropriate next step.
Arizona requires all private investigators to be licensed through the Arizona Department of Public Safety. That license requires a minimum of three years of documented investigative experience, an FBI fingerprint clearance, and a posted surety bond. It’s not a simple registrationit’s a credential that has to be earned and maintained.
The good news is that it’s publicly verifiable. You can confirm any Arizona PI’s license status directly through the AZDPS website before you hire anyone. This matters because unlicensed operators do exist, and hiring one creates real problems: evidence they gather may be inadmissible in court, you have no recourse if something goes wrong, and in some cases you could face legal exposure depending on how the investigation was conducted. We hold a current AZDPS licensethe license number is available on our website and can be verified independently. For Goodyear residents who are already dealing with a stressful situation, knowing the person you’re hiring is properly credentialed and accountable to a state licensing body is one less thing to worry about.
