For the past two years, our personal injury law firm has relied on the experience and professionalism that comes hand in hand when working with Sharp Investigations. Sadly, some of our clients are too injured to come into our office for consultations and Mr. Sharp and his staff are able to go visit them in their home, expressing empathy for our clients and working with our office as though we were one. We put a lot of pride into our firm, and we would not have been as successful the last few years if it weren’t for Sharp Investigations and their help.

Sharp Investigations, LLC did a background check on a prospective renter for a property I manage. I felt very confident that the renter would be a great tenant due to the thoroughness of his investigation and the report generated. Thank you!

Michelle Baker

Very professional people who got the job done accurately and effectively. My ex was located and served court papers within 3 days by these professionals (something DSS Child Support) didn’t do in almost two years. Harper Sharp assisted and was very helpful throughout the process. Quality customer service and professionalism is EVERYTHING. Thanks Sharp Investigations!!

I work at a law firm about an hour from Columbia and when we had a occasion for a process server in Columbia I found Sharp on the internet. I was very pleased with the service we received – from the office staff to the work that was done in the field. The communication was fabulous and they went above and beyond to accomplish a difficult service. Also, the price for the work was MORE than fair. I would 100% recommend Sharp for process serving and any other service they offer.
