Students in Dr. Leymon’s prior classes note the following about his teaching: 

“I have had Professor Leymon throughout my academic career at PSU. He was one of my first professors and I'm ending my academic career at PSU in his class. He took out time to help and guide me when I wasn't sure which direction I wanted to go in Criminology. Thanks to Professor Leymon, I am now in an internship exactly where I am a good fit. I enjoy Professor Leymon's classes and will miss him and PSU. I learned so much from his teaching and experiences. I hope everyone at PSU, in the Criminology field, has the opportunity to take one of his classes.”

 

“Professor Leymon has a lot of patience and dedication in his classroom. He works hard to help students understand hard topics and always lightens the mood with his sense of humor. He balances his classroom with applicable knowledge and challenges that allow each student to succeed if they put work into it. He is able to relate to students and is very approachable. Overall, he provides a good atmosphere for students to learn.”
