Entrust Your Histopathology Services to EPL
Companies who outsource the histopathology component of their valuable studies need to know that the work will be performed to the highest quality standards, on time, and at competitive prices. Although claims of quality are easily made, true quality can be a difficult metric to gauge. So let’s look at the evidence.

Unlike its few competitors, EPL has established a 45-year track record of proven performance. Strategically located in Research Triangle Park, North Carolina, northern Virginia near Dulles Airport, Seattle, San Francisco, Indianapolis, and Philadelphia, EPL is an employee-owned brick and mortar business that is not beholden to external stockholder expectations; nor are we impacted or distracted by acquisitions or harmonization efforts. EPL’s ideal size of approximately 110 employees provides us with the capacity and flexibility to handle large complex projects with rapid turnaround times, while concurrently offering personalized service.

When experience matters, it can be reassuring to know that EPL is managed, supervised, and marketed by on-site pathologists who are recognized industry leaders with global reputations.  More
