My sister and I recently hired David for a sensitive and time-critical matter, and I couldnt be more satisfied with the professionalism and results. From our first conversation, David listened carefully, asked all the right questions, and showed a clear understanding of how to handle the situation with both discretion and efficiency.
If we were ever to need a private investigator again I would use and highly recommend David and his company.
