Nice to meet you.

While the Pro-ficiency leadership team has an impressive collection of expertise and experience, we’re also a great crew to work with. We believe that we are ready to change the face of clinical research, and we plan to have some fun while doing so.

As he leads Pro-ficiency through their most recent growth and expansion strategy, the “client-centric” approach is already evident in the high-quality experience clients receive.
