"For me the pace and amount of material presented or made available for additional reading was just right.  Jason was on top of things when there was a computer glitch of any kind and promptly answered questions. Overall, I am very satisfied with the course."

William Buckley

"I have already used the watershed portion of the course in my fellowship to help prepare for a presentation. Thanks to Jason and his organization and insightful comments."

Wendy Doerner

"Overall a lot of really great information presented in a way that made it easy to understand. Online courses were straightforward and not overly technical, with avenues to get more technical if interested. In-person courses were well organized and very informative; the speakers for each were excellent."

Aiden Forsi

"I enjoyed the course materials immensely, especially all the added graphics, videos, and interesting additional online resources. I can only compliment the materials and pace of the course."
