A long-standing member of the faculty of the Susquehanna University High School Wind Ensemble Institute, Don-Paul has spent more than a decade teaching applied lessons, coaching chamber ensembles, leading sectionals, and mentoring advanced high school musicians preparing for collegiate study. Earlier university appointments include serving as Instructor of Saxophone and Clarinet at the College of Central Florida and Graduate Teaching Assistant in the saxophone studio at the University of Florida, where he taught applied lessons, woodwind methods, chamber music, and studio classes while assisting in the administration of one of the region's leading collegiate saxophone programs.

In addition to his long-term studio teaching, Don-Paul is regularly invited to present masterclasses, workshops, and guest lectures at universities, conservatories, festivals, and educational institutions internationally. His teaching engagements serve a wide range of audiences, including saxophone studios, wind departments, composition programs, and interdisciplinary arts communities. Topics have included traditional performance masterclasses, contemporary performance practice, extended techniques, collaborative approaches to working and collaborating with living composers, and the entrepreneurial realities of building a career in contemporary music. Drawing upon his artistic research, he also presents lectures on the development of new sonic possibilities for the saxophone, including his pioneering work on saxophone without mouthpiece and the artistic, technical, and acoustic implications of these performance practices.

Beyond traditional teaching environments, Don-Paul has contributed to innovative educational initiatives, including serving as Co-Director of Saxophone for Thrive from Music360, where he developed virtual curricula, coordinated masterclasses with internationally recognized artists, and mentored students. His educational work also extends beyond the conservatory through his role as a guide and educator at the Musical Instruments Museum in Brussels, Belgium, where he presents multilingual tours and educational programs exploring the history, construction, and cultural significance of musical instruments from around the world.

His former students have gone on to pursue graduate study at leading institutions, establish careers in music education and performance, and develop successful professional artistic paths of their own. Drawing from his international performing career, extensive experience commissioning and premiering new works, and close collaborations with composers across the globe, Don-Paul's teaching seeks to prepare students not only for the recital stage, but for meaningful and sustainable careers as versatile musicians in the twenty-first century.
