Was a very good course. I enjoyed Joel's teaching style, keeping things light and entertaining, but informational.

I came with zero spring knowledge and at the end of the course I gained a very good knowledge. Ken is super knowledgeable and his teaching really helped me understand the concepts.

Ken has provided very detail and easy follow instruction. he is really knowledgeable for all the topic of Spring! And he is really funny also. I have learned a lot and very enjoy his training class. Thanks!

Ken was great and very knowledgeable on all the topics discussed, as well as any topics brought up whether they were directly related or not. The course was great, and he was able to captivate the class rooms attention throughout the entire course. I would definitely be interested in someday taking some of his other courses.

Excellent instructor. Would definitely recommend. Knowledgeable and professional. Passionate about his subject.
