"GBS delivered the results that my team and clients required to be successful in my portfolio implementation. Without their clear understanding of the business requirements and our company culture our training rollout would have not been successful."
Christian Gunter, VP Bentell Kennedy Associates

"GBS has a deep and broad understanding of the LEED rating systems...they have been-to-the-mountain...and returned to provide us with great value on our investment."
Charlie Isaacs, Project Engineer Hawaiian Dredging Construction Company

"Perfect conjunction between theory and practice, all examples are real and this makes everything easier to digest. Order and content are in perfect balance so I personally find it hard to imagine an easier or better way to get LEED Green Associate Exam Prep."
Santiago Orendain, Ingeniero Administrador DMX - Mexico

"GBS worked with us from the start to develop a customized approach that tied the training content to our business, our projects and our geographic context. As this was the first LEED training in Russia we had high expectations that were exceeded by the expertise and professionalism they provided."
B. Kagan CeylanErnst & Young – Russia

"…Over 98% of those who attended the GBS course in 2009 went on to pass the LEED AP Exam. I was so pleased with the results and the feedback from my employees and customers that I knew we had to ask them to return again in 2010. Their expertise in green building principles is unmatched in the industry; we will continue to invite Green Building Services back to GE in the future."
Cate Gutowski North America Director of Sales- Retail & Commercial - GE Lighting

"Excellent walk-through of LEED-EB implementation from obviously experienced consultants. I would definitely recommend this course."
