Hire a Professional: Krofina P.I.

Service History

"I have been working with David J. Krofina of Krofina Investigative Services, Inc., since 1997. David's expertise has been of immense benefit to our firm. Dave is a true professional and can be counted on to give 100% to every case he handles."

Wylie A Aitken

Founder, Aitken Aitken & Cohn

"The hardest part of criminal defense is finding a good investigator. David J. Krofina solves that problem. He is fast, thorough, smart and knows how to follow up on leads without direction. His reports are camera-ready, and his photographic and documentation work is excellent. He testifies in a professional and businesslike manner. You can trust his work completely. I highly recommend him."
