About Us

NIGHTHAWK PRIVATE INVESTIGATIONS is a full-service, licensed private detective agency, established in 1990 by former military investigator, D. Wayne “Joe” Patterson. Built on integrity, intelligence, and experience, we have established a strong reputation throughout the state of California. We realize that for many of our clients, hiring an investigator may be a once-in-lifetime necessity brought on by circumstances that may impact the rest of their lives. When you hire Nighthawk Investigations, you can trust that we will do everything legally possible to positively affect the outcome of the investigation.  The success of your case will depend largely on your investigator’s skill, intelligence, resources, and integrity.  Hiring an investigator is not as simple as buying a new television or choosing which restaurant to dine at because, unlike everyday purchases, there can be lifelong repercussions in making the wrong decision.
Some of the more high profile cases we’ve been involved with include:
Peo v Scott Peterson – 2002
The Disappearance of Chandra Levy – 2002
U.S. v Mark Christian Anderson – 2009
 U.S. v Vang Pao, et al -2009
Isaiah Fowler murder trial – 2013

Our investigators are required to stay current of the latest developments in areas that impact our fields such as law and technology. We are passionate about our work. We have a deep appreciation for the fact that each client that trusts us with their case is quite often doing so with their life on the line.  We are members of the community as well, so rest assured that when you call us you won’t be speaking to an investigator in another city or state that contracts out your file to the lowest bidder. You have our guarantee that you will be treated with respect and confidentiality. Once we agree to work together, all our resources, experience, and intelligence will be immediately put to use in your case.


  • review rating 5  This is an outstanding company with outstanding investigators! Highly professional and extremely good at what they do. The founder and owner of the company is quite famous and has been in the business for years. What's also great about this company is they have not only ex-military investigators but they also have a retired NSA Army counter-intelligence agent working with them now. I highly recommend this company for any type of Private Investigations especially in San Diego County, Orange County, and Los Angeles County. I have heard their Northern California office is outstanding as well but I have only had first-hand experience with the Southern California office which has been top notch. I went through all of the reviews for the company and I agree with all of them except for the girl that claimed they stole her money. I thought that was an interesting comment as most likely what happened is she paid them a small amount of money to probably get surveillance on something and unfortunately private investigators cannot make miracles happen and it is not like Hollywood movies where they can push a button and get video footage from inside the bedroom from 10000 miles away. So if that person does not do something sketchy or suspicious during the time frame the private investigator is watching him or her, then there's nothing that they can do about it. I don't know if I would call that stealing but I think if you want really good results from utilizing a private investigator you should allow them one full day or more to perform the investigation. That way if anything at all happens they're definitely going to be able to find it. Especially this company. They definitely perform above and beyond from what I've seen working with other PIs.

  • review rating 5  I suspected my fiancé was cheating and hired them. My suspicions were true and I got the proof I needed. Better to have known before saying I do.
