I have never used Alessi Investigations, but I do know Nathan Alessi - and have for over a decade. He is a laid back and gregarious man, with a drive to do the right thing, find the truth, and is honorable, even when he doesn't have to be. I know several people who have used him, (Some at my recommendation) and none have been disappointed. If I had a need for a P.I. , there is no other I would turn to.
