personal and professional public history. Our
comprehensive background investigation will provide
useful background information and credential verification.

Skip Tracing | Witness Location - Locating persons that
have pertinent information regarding your case can be a
difficult task. CSISs investigators have the tools and
expertise to locate them.

Photo | Video Surveillance - CSISs investigators have
decades of surveillance experience using state of the art
technology to capture our subject's activities.

Activity Check - After a claimant accepts a settlement or is
awarded damages it is prudent to maintain an open line of
conversation. Through in person activity checks CSISs
investigators will confirm the claimant is alive and receiving
their benefit, as well as determine if the recipient's claim is
suspicious and warrants further investigation.
