I called GSL Data for the first time about 2 months ago because I had a last-minute and very big document production job. Two hours later they were in my office picking up the documents. It turned out to be a big job, far bigger(10x bigger) than we initially anticipated, but they were unflappable and very professional. They delivered the documents back to my office and stayed in contact the entire time. I also just recently had another job, which they also completed quickly, efficiently, and professionally. So far they are 2 for 2. They are now my go-to copying service and I’ve recommended them a number of times for both litigation support and for copying of paper healthcare records(because they will sign a HIPAA business associate agreement).
