A Little Bit About Us

American Information Specialists and the “Skip Trace Pros” have been around for about 20 years now. Mark Unger is a former Marine with many years experience as a Certified Private Process Server, Judgment Recovery Specialist, and Private Investigator in the States of California and Arizona. All Private Investigations are conducted through Unger Investigations.

We are real people – not just databases or software programs. We provide the best real-time locates and the most effective private investigations available anywhere in order to find your subject. We find people. Period.

Dan Unger and Matt Foley are also part of the business, and have very special investigative skills. We specialize in locating those hard-to-find people. Fast.

Here at American Information Specialists we wear many hats – but skip tracing is our specialty. We are the Skip Trace Pros. When it comes to Service of Process and Private Investigations, it’s all about finding your subject – in a timely manner. This usually means skip tracing – and we’re the best.
