From Kenya to an American Classroom: Carrying Purpose Across Borders
By Mr Dennis Bisera Isomba, October 13th 2026

When I think about my journey from teaching in Kenya to finding my place in classrooms in the United States, I think about more than the distance between two countries. I think about the learning, the courage to begin again, and the commitment to keep serving students while finding my own footing. The boy from Riaisomba village could not have understood every step that would lead here. Yet, looking back, I can see a purpose taking shape: to learn, to create, and to help others discover what is possible.

Teaching in Kenya became part of the foundation I carried with me. It shaped my understanding of education as a relationship between people and a responsibility to recognize potential, nurture curiosity, and give students reasons to believe in their future. Moving to the United States brought that purpose into a different setting. I brought my experience with me, but there was still much to learn. An international teacher enters a new classroom with knowledge and experience while also becoming a learner again. Unfamiliar systems, expectations, communication styles, and cultural references are common. Even ordinary classroom routines can require careful observation. Building trust takes time, and understanding a school community requires listening.

That experience can be humbling. It can also become one of the most valuable parts of the journey. I have learned that beginning again does not erase the work that came before. The lessons learned in Kenya still have value. My background still has value. My voice still has value. Growth means learning how to bring those strengths into a new community while remaining open to what that community can teach me. Across my nine-year journey in education from laboratory work through apprenticeship and into fully licensed teaching, I have continued to develop both my practice and my sense of purpose. Earning tenure became a meaningful milestone. Continuing my education and growing in leadership reminded me that a teacher’s development does not end upon receiving a license or entering a classroom.

There is something powerful about watching a student begin to see a personal idea as worth developing. A drawing becomes a design. A design becomes a prototype. A hesitant explanation becomes a confident presentation. Those moments help me understand why I continue. Through my work with the MakerLab and Makers & Leaders Lab, I am carrying that purpose forward: creating opportunities for people to learn through designing, making, collaborating, and solving problems. My journey has strengthened my belief that access to those experiences matters and that teachers can help students recognize possibilities that once seemed distant.

To a new teacher, especially a teacher beginning an international assignment, I offer this encouragement: give yourself time to grow into the new setting. You may be experienced and still need help. You may be prepared and still encounter uncertainty. You may love teaching and still finish a day exhausted. None of those experiences cancel your commitment or your potential. Ask questions. Learn the systems. Find colleagues willing to share their experience. Observe how students communicate and what matters to the community. Build relationships through consistency, patience, and respect.

Bring your culture into the classroom thoughtfully. Your journey can broaden students’ understanding of the world. Your willingness to learn can also show students that curiosity and humility belong at every stage of life. Remember that belonging often develops through ordinary moments: a conversation with a colleague, a lesson that connects, a student who begins to participate, or a classroom routine that finally feels familiar. Allow those moments to count.

And protect the energy that makes your work possible. I have come to believe that, as an innovator and an educator, you must know when to rest and remember why you cannot give up. Rest creates room to regain clarity. Support makes difficult seasons more manageable. A sustainable teaching life needs both. My journey from Kenya to the United States continues to unfold. I am still learning, still creating, and still discovering how to serve with greater understanding. When I look back toward Riaisomba village, I see roots that remain part of everything I build. When I look around my classroom in Maryland, I see the responsibility and opportunity of the present. When I look ahead, I see work worth continuing.

To the teacher preparing to cross a border, or already trying to find a place in a new school: carry your experience with confidence, meet the unfamiliar with curiosity, and give yourself the patience you offer your students. You do not have to understand the entire journey today. Begin with the students in front of you. Teach with care. Learn with humility. Let each day give you something to carry into the next.

A journey that begins in one classroom can reach far beyond it.

A Reflection on Service, Growth, and Educational Impact

By Mr. Dennis Bisera Isomba - June 6th 2026

There are moments in life that invite us to pause and reflect not on personal accomplishments alone, but on the journey, the people, and the purpose that make those accomplishments meaningful.

I am deeply honored and humbled to share that I have been nominated for the AAASBE Teacher of the Year award within my school district. I extend my sincere gratitude to the Ann Arundel Alliance of Black School Educators for this recognition and for their continued commitment to celebrating excellence in education.

What makes this nomination particularly meaningful is its timing. It comes as my first freshman cohort since joining Castle – North County High School reaches graduation. Watching these students walk across the stage has been a powerful reminder of why educators do what they do. The graduation ceremony was not simply a celebration of academic achievement; it was a testament to growth, resilience, perseverance, and the collective effort of students, families, educators, and the broader community.

As an international educator, this milestone carries special significance. When I arrived in the United States, I entered a new educational system, a new culture, and a new community. Like many educators, I quickly learned that success is not built overnight. It is built through consistency, service, humility, and a willingness to learn.

There were many days when the greatest achievement was simply showing up and giving my best effort. There were moments of uncertainty, challenges that stretched my experience, and lessons learned through both success and failure. Yet those experiences reinforced a principle I often share with my students: the hardest and most important step is to begin.

Growth rarely occurs in comfort. It happens when we embrace challenges, learn from productive failure, and commit ourselves to becoming better than we were yesterday. Whether in the classroom, the makerspace, STEM programs, or leadership initiatives, meaningful progress comes from continuous learning and intentional action.

As we await the announcement of the finalists, one thing is already clear: my students, their families, and our community are benefiting from the daily sacrifices made by educators who dedicate themselves to serving others.

The true reward is witnessing a student gain confidence in their abilities. It is seeing a learner discover a passion for science, engineering, or technology. It is watching young people develop the skills, character, and mindset needed to become future innovators, leaders, and contributors to society.

Every lesson taught, every mentoring conversation, every opportunity created, and every challenge overcome contributes to a larger mission: preparing students not only for careers but for lives of purpose, leadership, and impact.

This nomination also serves as a reminder that education is never the work of one individual. I am grateful to the school leaders who have provided guidance, the mentors who have shared their wisdom, the colleagues who have collaborated and inspired, my family and friends, the families who have entrusted us with their children, and the community partners who have helped create opportunities for students to succeed.

Most importantly, I thank God for the strength, wisdom, and opportunities to serve. Every achievement is built upon the support, encouragement, and faith of countless individuals whose influence often goes unseen.

My hope is that this recognition encourages educators everywhere to continue showing up with purpose and passion. The work we do matters. The relationships we build matter. The opportunities we create matter.

At a time when education faces increasing challenges, the need for educators who advocate for access, representation, belonging, innovation, and student success has never been greater. Every classroom has the potential to change lives. Every educator has the opportunity to inspire future leaders.

Whether or not my name is ultimately called among the finalists, I remain grateful for the privilege of serving students, learning alongside colleagues, and contributing to the development of the next generation.

Because at the end of the day, the greatest recognition is not an award it is knowing that our work is helping shape lives, strengthen communities, and prepare future global leaders.

"The impact of an educator is measured not by the recognition received, but by the lives transformed, the opportunities created, and the future leaders inspired through daily acts of service."

Exploring Nuclear Science Through Practice: Reflections from the ANS Educators Workshop

By Mr. Dennis Bisera Isomba - November 15th 2025

Today provided a rare and enriching opportunity to step directly into the world of applied nuclear science during the American Nuclear Society’s Educators Workshop inside the historic NS Savannah. The experience moved beyond abstract theory and immersed educators in practical demonstrations that revealed the true breadth of nuclear energy’s potential.

For many in the public, nuclear technology is often framed through catastrophe, myth, and fear. The narratives we hear from popular media to historical events tend to overshadow the essential truth that nuclear science, when responsibly applied, is a powerful tool for societal advancement. This workshop served as a necessary counterbalance.

Engaging with experts and hands-on activities clarified how nuclear energy contributes far beyond electricity generation. From medical imaging and cancer treatment, to agricultural innovations, space exploration, water purification, and advanced materials research, the applications are far-reaching and deeply transformative.

The workshop reinforced an important idea for STEM educators: the responsibility to bridge the gap between perception and reality. When students understand the science its safeguards, its innovations, and its global value they develop a more accurate, evidence-based perspective. They also begin to see opportunities for careers, research, and problem-solving in a field that will remain vital to humanity’s energy and technological future.

Nuclear science is more than a headline it's a system of knowledge capable of saving lives, powering progress, and inspiring the next generation of innovators.

“When we replace fear with understanding, science becomes not a threat, but a tool for building a better world.”

Today's workshop reaffirmed that mission. And as educators, the work continues: to teach with clarity, challenge misconceptions, and guide learners toward truth grounded in evidence, curiosity, and responsible inquiry.
