We manage an extensive international network of Partner Affiliates, through which we provide our clients with nationwide and worldwide investigative and expert witness services, 7/24. In addition to our own team of investigators, our family of “Partner Affiliates” consists of fully licensed current or former law enforcement officials, with specialized skill-sets, supported by a select group of insurance, forensic and technology professionals. All have been rigorously screened and vetted to ensure that levels of client service, professional acumen and ethical conduct are consistent with our own.

With CASTCorp International, there is no need to spend hours or days searching the internet, or conducting telephonic interviews, in search of the right fit for your investigative needs. We have put the finest, most qualified, most experienced and most ethical professionals all together under one umbrella. And, with our case management system, our clients may expect to have all of their investigative needs, be they single-issue, or more complex, requiring the application of multiple disciplines and skill-sets, managed for them by a single Case Manager, in the most efficient and cost-effective manner possible.

Through CASTCorp International and our Partner Affiliate Network members, licensed investigative and expert witness services are available throughout Canada, the Caribbean, Central America, Mexico, South America and the U.S., along with much of East Asia and Western Europe.
