What Members Are Saying ...

"Courses at the ISSP taught me it’s all about relationships when it comes to a sustainability agenda. I started the courses enthusiastic about the content but downhearted about the opportunities for change where I work. I’m ending on a note of gratitude and delight because my fondest hopes for sustainability at my company are being realized. None of this change would have occurred without being enrolled at the ISSP. I learned that it takes a village to pursue a sustainability agenda." Andree Iffrig, LEED AP, Calgary, Canada

“ISSP has been front and centre for honing my understanding of what a sustainability professional is. Attending online webinars and engaging with certificate and cohort colleagues have been invaluable investments and tremendous fun.” Steve McCoy, Counterpoint Consulting, Kuala Lumpur, Malaysia

“Through attendance of ISSP events, I have met a wealth of sustainability professionals that I can connect with and learn from. I felt compelled to help form a steering committee that would launch a local Greater Washington DC Chapter for my region. Serving on the committee and planning events has been truly rewarding because I get to meet people who are passionate about their work and inspire me to see more possibilities for the future I envision for both my career and my personal life.” Jenn Truong, Virginia Tech's Center for Leadership in Global Sustainability
