Knapp was driven to become a teacher because of his deep passion for history and a desire to inspire his students with the stories of the past. He believes that understanding history helps students grasp the complexities of the world today. Outside of the classroom, Knapp immerses himself in creative pursuits, particularly painting, where he finds joy in expressing his thoughts and emotions through art. He also has a voracious appetite for literature, making it a personal goal to read three books each week. This habit not only enriches his knowledge but also enables him to bring fresh insights into his teaching. Among all the subjects he teaches, his favorite is World Cultures. In this class, he enjoys delving into the rich tapestry of human experiences, sharing extraordinary stories that celebrate the diversity and interconnectedness of cultures around the globe. Ethan Hagenbuch, a sophomore at GPHS, expresses his admiration for Knapp, stating that he is an exceptional teacher who genuinely engages his students. According to Hagenbuch, Knapp has a unique ability to make learning enjoyable by infusing humor into his lessons, which not only captures the students' attention but also creates a positive and lively classroom atmosphere. Knapp makes a concerted effort to include every student in discussions and activities, ensuring that no one feels left out. This inclusive approach fosters a sense of belonging and encourages all students to participate actively in their education.

Knapp emphasizes to his students that high school might be the final opportunity to receive an education without any financial burden, urging them to seize this chance wholeheartedly. He believes it is crucial for students enrolled in his class to approach the study of history with an open mind, recognizing that the people they learn about were not just figures in a textbook, but individuals who lived rich, diverse lives. These historical figures experienced their own joys, sorrows, triumphs, and struggles, much like we do today. Their stories, often overlooked, hold significant value and relevance. Knapp aims for his students to finish his class with a deeper understanding of their connection to these past lives, appreciating that they are part of a long continuum of human experience—an enduring narrative that has shaped the world we inhabit and will continue to influence future generations. Through this perspective, students can gain a greater appreciation for history and their role within it. Andrew Thomas, a sophomore at GPHS, shares that one of his favorite aspects of Knapp is his incredible sense of humor. He explains that Knapp stands out from other teachers because he knows how to make the lessons engaging and enjoyable, turning what could be a typical class into a fun experience. Thomas particularly values Knapp's brutally honest approach to teaching; he appreciates how straightforward and genuine Knapp is with his students. This level of honesty provides a refreshing change of pace from the more conventional styles he has encountered in other classes, allowing students to feel more comfortable and open during discussions.
