What Our Clients Say About Us

R M. Client

San Jose Detective Agency was very responsive and professional in helping me with my situation. They provided me with the information I requested in a timely manner, and gave me helpful advice in addressing issues that were causing me concern. They spoke with me over the phone and gave me valuable information that was helpful in achieving results. They are honest, patient, and compassionate. I highly recommend SJDA.

Jeremy W. Client

I called to request assistance in my matter and Ray was extremely helpful offering both information and advice to help me reach my objective. He spent almost a full hour with me on the phone, didn't rush me to make sure he fully understood all the aspects of my matter, and did so on the spot, without an appointment, and without charging a service fee. He seemed like a very straight shooter, honest, knowledgable, and responsible. Although, I did not use his service this time I cannot say enough great things about him and plan to hire him for my next event and refer him to my friends.

Jackie H. Client

Very helpful and patient. I felt better after talking to Jay. He even explained how I could get the information I needed without hiring a detective.

RT C. Client

I recently had San Jose Detective Agency help me with a private business issue. They were very quick to respond to my call. They provided a number of different paths to take - with varying costs so I had some options to match my budget. In the end, the investigator who worked with me was professional and resolved my issue promptly with the desired result. Thanks!!

Elizabeth K. Client

Used San Jose Detective Agency to install a top of the line security system at our place of business...great job! Very happy with their recommendation of security system product to purchase and have installed. Was also very pleased with the timeliness and quality of their work.

Nicole G. Client

Used San Jose Detectives to do a background check on my nanny. Was very impressed! I only had limited information but they were still able to do it successfully. Prompt with the results. Would definitely recommend them to a friend.

Mike M. Client

Ray of SJDA helped me with a fraud case. First he found out all the information that could help us and did it within one day. Then even more impressively, Ray made suggestions that helped me with my discussions with the police. This information was crucial to allowing us to pursue the case, instead of it getting sidelined. I can't recommend their company highly enough!
