Our Focus

At Estes-Zako & Associations Investigations, our focus is to obtain complete, accurate, unbiased, and admissible courtroom evidence that will protect your integrity and help you make informed decisions.

It is our mission to provide you with superior service, quick turnaround time, and unmatched capabilities, experience, and resources at the most reasonable rates.

Why Hire Us?

Unlike national investigative companies, we are a smaller agency with fewer employees. The investigators at Estes-Zako & Associates Investigations are professionals and have experienced backgrounds in law enforcement, business, the military, as well as with prior private investigations.

We use quality state-of-the-art surveillance equipment. Our employees receive ongoing training to keep up with modern technology, pertinent laws, and professional ethics, and we consistently keep pace with the ongoing changes in the field of private investigations.

We provide superior investigative services. Unlike the larger companies, we treat you as an individual, not a number. We take the time to listen to your story and help you come up with a plan of action, so that you can see your investigation through to the end. Consultations are always free.

Estes-Zako & Associates Investigations is ethical in conduct, uses discretion, and provides the utmost confidentiality in all of our investigations.

Although we are a for-profit company, money is not our bottom line. Our clients are often surprised and pleased when we find shortcuts and reach our goal before reaching the client’s set budget.

My name is A. Joseph Zako, California State Private Investigator License No. 12465. In 1952, Robert A. Estes, Sr., California State Private Investigator License No. 3430, started a small company with a unique commitment to help clients. I started working with Mr. Estes in 1985, and we became partners in 1987 after I received my Private Investigator license. I became the owner of the firm after his retirement in 1993. Estes-Zako & Associates Investigations continues to build relationships and partner with clients, and we continue to ensure the highest customer satisfaction rates in the industry.
