I hired Driscoll Investigations for all of my investigative needs.  They are thorough, professional, and communicate well with me and with witnesses.  Even witnesses who I believe will be reluctant to talk usually talk to the investigators for Driscoll.  Reports are only written when I request them – and then the reports are excellent and detail-oriented.  I recommend them highly.

A little over a year ago I was referred to Driscoll Investigations by a colleague of mine. This colleague walked into court stating that she had "never felt more prepared for a hearing" then she did on that day because of the unbelievable work that her investigator had complete for her in such a short time.  Upon hearing that I immediately contacted Driscoll Investigations and I can absolutely say I agree with my colleague completely. I have worked on many cases with many different investigators at Driscoll Investigations and I have been beyond impressed with each and everyone I have had the pleasure of working with.  I never have to micro manage any of them and all of the investigators update me in an extremely timely manner.  I could go on for hours about all of the positive experiences I have had using Driscoll Investigations, but I will just stop here and say that in my opinion Driscoll Investigations have the best investigators in the Commonwealth!

It is with great pleasure, and no hesitation, that I recommend Dennis Driscoll and his team at Driscoll Investigations.  I have been relying on Dennis to conduct my investigation needs for my law firm since its inception.  Dennis and his team have been reliable, prompt, and thorough.  They have found witnesses who would otherwise have never been known to me, found cracks in cases that at first seemed strong, tracked down and collected evidence, and provided valuable insight that I have used (and relied upon heavily) for my criminal defense cases and trials.  What is more important, Dennis and all of his investigators are quick to provide their suggestions, willing to follow specific paths that I need, and are all pleasant and professional.
