Gwen’s engaging teaching style and willingness to personalize the class content to our group’s particular interests made my time spent in her GRI Certified Standards course enjoyable. Her experience with ESG reporting and accounting make her a valuable resource and I am glad to have participated in her training.

Learning CDP and GRI metrics are part of being competitive as a consultant in Sustainable Development now.  Its hard to make learning standards of verified social and environmental performance, public transparency, and legal accountability dynamic — But Gwen made the sessions interactive and ran us through case-study scenarios.  Well worth the investment and time to take the course through the ISOS group, hopefully you will get Gwen as your instructor!
