- Roger L. Bertolini - Limited Systems, LLC

The GRP accreditation program stands out as one of the most comprehensive and intelligently designed sustainability training courses I have taken. GRP accreditation gives my organization the knowledge and credibility to guide our clients through the benefits and proper implementation of a successful green roof.

- Stefan Hansmire - Ncompass Construction LLC

This course is not for the faint-hearted. It required several hours of study every week, but as someone new to this field I came out of it with an excellent understanding of green roof design and installation techniques. The combination of lectures, materials and forum discussions was very effective.

- Julia Hitz, Bronx River Alliance

This self-pace course provided a very in-depth education on all the components and processes involved in the design, installation, and maintenance of green roofs. This course has provided me with the knowledge necessary to pursue the career I've always wanted and has given me confidence that I have the right skills to be a successful Green Roof Professional.

- Kloe Belush Masters Student, Indiana Universtity

I have taken many distance courses in the past, and the green roof professional course was the best distance/online course I have taken. The videos did an excellent job at explaining anything that might have been confusing from the course manuals. The content was very informative. I truly wish all courses were delivered as well as this course.

- Garratt Grenier Field Advisor, Tremco

Great introduction into the world of Green Roof Design, maintenance and installation!

- Adriana Turczyn Graduate of Landscape Architecture

The course has valuable information and allows you to study remotely and mostly at your own pace. I'm very satisfied with the knowledge I have on green roofs after taking the course.

- Nanci Fioravanti Account Manager, The LaurelRock Company

This course offers more than enough knowledge and resources to become a green roof expert in a short amount of time.

- Megan Lynch Landscape Architectural Designer, Benner Landscape Architecture

It's a good basic course to introduce people to the roof gardens categories, methods and even bidding. Although once finished you definitely need to put all this knowledge in practice to reinforce it and, mainly, to start doing something useful for the people and for the nature.

- Julyo Espinoza Environmental Projects Coordinator

It was good to be part of the first online course. I expected some technical challenges as it was new to this format. I was pleased with the content and learned a lot.
