Surveillance

One of the most useful way to gather evidence in the industry. Our teams specializes in covert surveillance investigations - whether it be insurance claims, corporate investigations, domestic surveillance, and more.

 

Backgrounds

Pre-employment background screenings (with credit reports, if needed) and general, public records background searches are available. We’re able to search criminal/civil records, verify education, previous employment, liens/judgments and more.

Asset Searches

An extremely useful tool for attorneys and private clients alike. We’re able to supply clients with property records, vehicle ownership information, and place of employment. Banking/account information can often be obtained.

 

Social Media

Social media searches are quickly becoming a standard tool in the investigative field. Locating and monitoring an individual’s social media activity can help you make informed decisions on who you’re bringing into your home, office, or school.

Locates/Skip-Trace

Our team uses a variety of methods to locate individuals. Each assignment could include searches into public record, social media, credit headers, phone and email records, and business records to determine a current, verified address.

 

Process Service

We specialize in locating and serving individuals that have otherwise been difficult to serve. We employ a variety of techniques and have access to resources that standard process servers don’t - we have a near 100% success rate on process service cases.
