I am the pastor of Epiphany Lutheran Church in Castle Rock, Colorado. Our church has relied on the excellent services of Advanced Professional Investigations (API) for our criminal background checks on staff and volunteers for almost a decade now. They have also advised us on security concerns. The whole team at API is fast, responsive, and knowledgeable. We appreciate their expertise, and you should too!

As friends and colleagues of Robert and Andrea at API, I am proud to share my personal and professional thoughts and experiences. First, we do not provide surveillance - we refer clients to the best we know in API. They are more than surveillance and more than professional investigators. Work product is important - and as important are experience, skills, knowledge, integrity and ethics. I have worked in PPIAC and NCISS with Robert & Andrea, I know the dedication they have to their clients and our profession. and it all comes from having those personal and professional traits.
