Our team

Rajneesh Mitra

Founder and Director

A pharma-legal professional who holds 30+ years of rich and comprehensive experience in the areas of Govt. Liaison, Public Relations and Regulatory Compliance for reputed pharmaceutical companies in India. Handling statutory compliances with respect to sale, purchase, possession, use, import and export of NDPS substances for pharma companies has been a primary responsibility in his wide-ranging profile.

In coordination with IDMA, he has played a key role in flagging issues with respect to discrepancies in NDPS regulation. The intent was to draw law-makers’ attention towards the barriers that pharmaceutical companies face in the legitimate use of narcotic and psychotropic substances for medicinal or scientific purposes. While participating is workshops and seminars on NDPS, he realized that pharmaceutical companies do find it complex and cumbersome to comply the tricky and ever changing NDPS regulations. An interest in and a sound understanding of NDPS Regulations with respect to pharmaceutical operations, was the driving force that made him to set up DILIGENT ASSOCIATES.
