About Us

#1 Selling LEED Exam Prep Since 2007
LEED and WELL Education Experts

Our Story:

Green Building Education Services (GBES) was founded in 2007 (back then we were www.greenexamprep.com) and created the original LEED practice tests as the LEED movement was growing. Our co-founders brought together real estate/construction/green building experience as well as professional credentialing and exam prep systems. The perfect match. Today, GBES is recognized as a global green building movement leader.


It is the vision of GBES to become the global leader of sustainability education and training.


It is the mission of GBES to inspire people to advance global sustainability through best-in-class education and encouragement.

Core Values:

  • Quality of Life: Proactively create a healthy work-life balance and consistent enjoyment in day-to-day life for our family (team) and our community.
  • Best-in-Class: Global notoriety as a trendsetter and influencer in all that we do: education, relationships, and customer service.
  • Positivity: Passionate practice of optimism and environmental stewardship in the present about the future.
  • Trust: Faith in each other, goodwill towards our customers & clients, and consistent integrity.

  • After our LEED practice tests, we added courses and additional study tools. LEED went through major changes in 2009 (to v3) and multiple new LEED credentials were available (that was a busy year for us to make practice tests and courses for each LEED credential). Then, we built out a 100+ continuing education (LEED CMP) library that also doubles for AIA hours. Now, we’re all-in on WELL, a program we really enjoy.

    Green Building Movement Leaders:

    We are proud to be the leading provider of online LEED Green Associate and LEED Accredited Professional (AP) exam preparation solutions and services. GBES is the top provider of web-based realistic exam simulation and online training tools for the LEED Green Associate and LEED AP exams.
