Client Testimonials

If you find yourself in need of a PI, I can assure you that retaining Cowan Investigations is 100% the right choice. Bob and his wife Liz worked tirelessly to assist me with a very challenging situation and ultimately were able to exceed my highest expectations in terms of obtaining evidence. I truly cannot thank them enough for the level of care and professionalism they brought to my case.

Bob and his team were great to work with. Extremely responsive and helpful, and really seemed to know what they were doing. They were able to obtain evidence for my pending financial support case that demonstrated my ex-wife was physically fit for work contrary to her claims of various “health issues” preventing her employment. I would definitely hire Cowan Investigations again if I ever need a private investigator in the future.
