Testimonials, Los Angeles Detective Agency


Hello Mr. Gollaz,


I'm in awe at your extraordinary work you have rendered, as well to the swiftness of locating Ms. “ … ”.  Soon after reading your email, I sent a text message to “ … ” to share the good news and I sensed that by her response that she was ecstatic when she sent me an enthusiastic-looking smiling emoji as a result of your phenomenal investigative skills and talent.


Mr. Gollaz, I am genuinely grateful once again for your assistance and for rekindling our friendship that had begun a little bit more than 30 years ago.  It was through my girlfriend at the time, “ … “, that our lives would intertwine. Moments that were filled with many joyful moments, until one spring day during the month of April back in '89 when it all abruptly came to a tragic end.  


Through her loss, we all discovered that we never forgot each other during the past three decades.  


Once again, I thank you.

I was extremely satisfied with your extraordinary service when Mr. James Gollaz's expertise was able to assist me about a year ago in locating a fond friend of mine, Ms. " ... ".  Since then we have been in close communication. Thank you for your phenomenal service!

Kudos to James and whoever, if anyone, assisted him in searching for my best friend. In just a couple of days, he's done more than I was able to accomplish in three years of looking for him. He's not actually found at this writing, but I expect, because of James' efforts, to finally locate him very shortly! When you hire a detective - someone you don't know - on the phone and send him in, you naturally wonder if he's really doing the job. James came with data that told me, beyond doubt, that he does what he says! He could not make this stuff up. I'm very pleased with him and Los Angeles Detective Agency and I recommend them highly! Thank you, James! And, thank you LADA!

Hello Mr. Gollaz, I would like to take a minute to thank you more than anyone for everything you did for me. All your hard work and dedication and you always believing in me when others wouldn't motivated me not to give up. Without your help who knows if at this moment I would be having dinner with my family. I will always be so thankful to you for finding out the truth and proving my innocence. Once again thank you for everything and happy thanksgiving. Best wishes to you and your family for the holidays.

I am a criminal defense attorney who has worked with Private Investigator James Gollaz. He is a fierce fighter in investigating and searching for the truth. An example of this was a difficult burglary case we recently worked on where my client was accused of stealing from his employer. There was positive identification of my client by 2-3 employees but my client insisted and swore he was not working that day and was home. The evidence against my client was stacked and no one was believing him. Detective Gollaz was able to track down and find the true person who committed the crime and we were able to convince the Pomona Courthouse Prosecutor to drop all the charges (very rare in Pomona court where they have a 99% conviction rate). Detective Gollaz found the person who used the exact Uhaul rental to commit the burglary, ran a DMV license check and found his DMV photo looks almost exactly like our client! There was still work yet to be done. Detective Gollaz was also able to track down the actual perpetrator's cell phone information and connect the calls he made to the scene of the crime! Doesn't just happen in the movies, it happens with James Gollaz! A good lawyer turns into a great lawyer with a great investigator like Detective Gollaz. Thank you James for stellar work - as always!

Richard Berkon. Attorney, San Diego, Ca.




On April 11th I was involved in an incident with Pomona Police Department and my attorney referred me to Gollaz and Associates to interview some independent Witnesses. I'm really pleased with their services because they were really quick and accurate. Also, the prices for the services provided were more than fair and Mr. Gollaz was really professional and respectful. I like how they always kept me inform about what was going on with the interviews of the witnesses. His interviews and professional skills helped me and my attorney to obtain a non guilty verdict. I'm really pleased with their services.
