Holl Investigations hired us(another private investigating firm) in Tavares Florida. We were hired to dig up information on several individual and any companies they were associated with in Florida. We dedicated an investigator for 40 hours who submitted a report and invoice of $ 2400. Holl will not pay a dime. A formal grievance was filed at NAPPS of which he was a member. He refused to respond to the grievance and was subsequently dropped from membership roles. Dave John Holl, the owner, will not answer calls or emails. It appears this company/individual is highly unethical at best and criminal at worst.
