"Hi Jim, I just wanted to let you and the rest of Ron Blank and Associates know how heavily I relied on your materials for my LEED credential continuing ed!! My deadline was June 6th and I used MANY GreenCE online classes to fulfill my requirements. They were typically interesting and easy to understand and I really appreciate your prompt registration with USGBC after I completed a class. Thanks for the help and for making it so easy to do. Sincerely, Ellen"
