PI Magazine / PI Gear

I connected with Patrick Collis and Preston Hocker, co-owners Spartan Investigations & Executive Protection in 2023. PI Magazine featured them on the July/August 2023 cover of PI Magazine. Patrick and Preston also created Guardians, https://guardians-us.org/ a nonprofit organization dedicated to raising awareness and providing services for victims of domestic violence and human trafficking. Spartan Investigations & Executive Protection was recently featured on an episode of Trafficked with Mariana van Zeller — Season 5, Episode 6 airing on National Geographic and streaming on Hulu & Disney+

We are grateful to have their support as a top sponsor of the
PI Magazine Human Trafficking Conference taking place on 4/21. https://pimagazine.com/human-trafficking-conference/

I am honored to have Patrick Collis and his COO Ron Haugen join us on this day and spend a few minutes speaking to our attendees about the services, and training provided by Spartan Investigations & Executive Protection to investigators and the public in an effort to combat and bring an end to human trafficking. If you are attending the conference, I highly recommend you take a moment to meet these gentlemen.

I want to thank Larry Warwick, Thomas Fischer and the Professional Association of Wisconsin Licensed Private Investigators (PAWLI) Board for having me at your annual conference. It was great networking with professionals in this space and I was happy to see friends from a year ago. The hospitality event was especially fun! I am grateful for your loyalty and support over the years and am excited to keep building this partnership.
