Teachers, as key sources of student information, must excel in their profession, particularly in pedagogical content knowledge. This presents challenges for those without education degrees, who may struggle to translate their expertise into effective classroom strategies. This study explored the lived experiences of Development Communication graduates teaching English in Davao Oriental public secondary schools, using Interpretive Phenomenological Analysis (IPA) to understand their transition into teaching. Eight graduates from Mati City and Davao Oriental Division schools participated in in-depth interviews. The analysis revealed themes related to their experiences: importance of modifying their teaching strategies to accommodate the varied learning capabilities and styles, teaching journey led them to develop a sense of fulfillment, the challenges faced with students struggling due to weak foundational, strong desire for content-specific training to enhance their skills, particularly in grammar and pedagogy relied on creativity, innovation, and personal resilience to overcome their struggles and improve their teaching practices, and emotional struggles such as self-doubt, exhaustion, and anxiety became a source of growth and motivation. Participants' experiences reflected challenges, opportunities, and growth associated with this career shift. The findings indicate that transitioning to English teaching is a multifaceted experience involving ongoing challenges and the pursuit of professional and personal growth. Participants emphasized continuous learning for adaptation and meeting diverse student needs, aligning with contemporary educational theories that advocate lifelong learning to enhance instruction and prevent burnout. The study highlights the need for targeted professional development for teachers from non-education backgrounds to support their success and student achievement.
