Private Detective Services

Someone you can depend on to do the job

What you want from a process server is someone you can depend on to do the job. As an attorney, you want to hear that your documents have been served; you don’t want to get a long story about why they weren’t. These guys are the kind of process server that get the job done without any hassle or excuses. I have enough to worry about on a case without having to wonder whether subpoenas have been served. This team of servers made sure I don’t have to.

They went to great lengths to affect the service

A lot of attorney’s offices don’t fully understand what private investigators have to go through sometimes in order to serve documents. We sent the folks here a serve job we thought was going to be easy. It was anything but that. When I found out that the subject was intentionally eluding service, I asked the office staff to keep me filled in on everything they were doing, because I was curious. They went to great lengths to affect the service, including stakeouts and a number of ruses to get to the subject. Not only did get my documents served – I’m never going to take process servers for granted again.

An e-discovery job

I didn’t think that a PI firm could handle an ediscovery job – I’ve been a paralegal for years. Then my firm started working with this company. Sure enough, 1privateinvestigator has an ediscovery team that got through a complicated assignment far faster than a lot of independent firms take. I’m beginning to realize that they can take care of all our pre-trial needs.

Best process server firm in Southern California

Being a paralegal, I know that a lot of PI and process server firms can be very hard-boiled and gruff over the phone. These guys are different: every time I’ve called them with a job, they’ve been both efficient and courteous. It’s nice to know that if your boss barks at you about a service of process job, you won’t get barked at by the process server firm…no matter what demands you’re placing on them.

Best process server firm around, bar none.
