Training Partnership with STOBG & ISPE


As part of the Life Sciences Initiative, we have contracted with the International Society for Pharmaceutical Engineers (ISPE) to deploy a certification class around Good Manufacturing Practice (GMP), the recognized standard that pharmaceutical clients recognize when prequalifying CM firms. This training will provide a foundational, baseline understanding on the guidelines, procedures and activities that will be requirements in a cGMP manufacturing facility. In such a facility, the contractor would be responsible, accountable and shall be informed about cGMP requirements for any type of project.
