Students in Greg’s prior classes note the following about his teaching: 

"Summer '17 was my first term back to college after 15 years away. [...] I was completely anxious about taking CCJ 200, which I was only taking as part of my UPA degree requirement. Professor Stewart blew me away! He was encouraging, thoughtful, organized, helpful, funny, thought-provoking and absolutely brilliant. I asked him if he is teaching any classes in the fall so I could keep working with him (he is not :-( ). Because of him, I decided to stay in UPA instead of changing majors to Communications, and the classes I'm most interested in now are CCJ. Thank you thank you thank you for having such an amazing and engaging teacher for what could have easily been a throw away online class."


"I am very impressed with Sgt. Stewart. He is focused, knowledgeable and thoughtful. A lot of what we covered brings out strong feelings for certain people, and normally biases run rampant in this field or over these topics. Not so with Sgt. Stewart. He provides multiple ways of looking at a highly complex subject, has a huge amount of practical experience, and is a good educator. I would happily take another course from him."


"This instructor was something else. He was very caring, organized, didn't bash people for their opinions on certain subjects, and was very helpful with anything I needed help on. He shows a great amount of care in what he teaches and he was a good instructor. Being that he is also a sergeant in the Portland Police Bureau it was great to have a professor that is actually law enforcement."
