At Harper, our core strength is the combined knowledge and effort of our unique and multi-talented employees, creating an authentic environment of innovation and collaboration. From engineering to accounting, marketing to manufacturing, Harper’s employees are challenged to think differently every day.

Dr. Prasad Apte - Harper International« I’ve developed several processes from lab scale through commercialization throughout my career as a material scientist prior to joining Harper. The most critical stage is going from small to large scale and to a continuous process. The differences in each process or material development are interesting and challenging, and this is where Harper’s expertise shines through when we partner with our customer. »
