Attending the International Master Florist Certification program at the Boerma Instituut, in Aalsmeer, Netherlands, was a transformative milestone in my professional journey as a floral designer. Under the instruction of German Master Florist Gregor Lersch, I was immersed in an intensive curriculum that expanded both my technical skills and creative perspective. The program challenged me to think more intentionally about design through principles such as formlinear composition, the Golden Rule, vegetative design, displacement, and the relationship of contrast. I also gained hands-on experience with bouquet frames, plant design, bridging and scaling, large room installations, and the importance of precise nomenclature and sketching as foundational tools for planning and execution.
Throughout the course, I explored new techniques that pushed me beyond my comfort zone and encouraged innovation. I developed a deeper appreciation for structure and storytelling within floral design, learning how to balance artistic expression with technical precision. Each project
reinforced the importance of mechanics, proportion, and harmony, while also allowing space for personal interpretation and creativity.
The final examination consisted of five components: botanical identification, a bridal bouquet, a freestanding hand-tied bouquet, a buffet piece, and a displacement design. I am proud to have graduated cum laude, meaning “with honors,” as my scores remained consistently above
average. I was especially honored that my work resonated with the judges.
My use of deconstructed Alpinia in a highly decorative application stood out, as did the well-defined and layered color palette in my displacement piece. My buffet design demonstrated strong use of repetition and was constructed entirely from scratch, while my bouquet frame featured elongated feet and incorporated wool alongside botanical elements, showcasing both texture and structural creativity.
My experience at Boerma Institute profoundly elevated my design style and reignited my passion for flowers. It refined my approach to floral artistry and strengthened my confidence in both conceptualizing and executing complex designs. I am deeply grateful to the American Floral
Endowment for providing the scholarship that made this opportunity possible. Their support has enabled me not only to achieve this personal goal but also to give back to the floral community by sharing the knowledge and techniques I have gained. I am committed to helping others grow in their craft, especially those who may not have the opportunity to travel, ensuring that this education continues to inspire and uplift the industry.

I had the privilege of attending the MF course with Gregor at the Boerma Institute and it has been the most wonderful learning experience for me. The teaching was exceptional, led by a world-class master who brought unparalleled expertise and passion to the classroom. The curriculum and course content were also outstanding, providing a comprehensive and engaging exploration of the subject matter.
Overall, I would highly recommend this course to anyone looking for a transformative learning experience. The combination of excellent teaching, rigorous curriculum, and exceptional support provided by Boerma made it an unforgettable journey that I will always treasure
My experience with the International Master Florist certification has been the most immersive and richly layered education of my career—an environment steeped in history, technique, and advanced theory that defies simple description. Gregor Lersch, a true treasure in our industry, infuses each day with a unique blend of humility and infectious passion that radiates from both his teaching and his work. Mornings began with Gregor unveiling inspired designs, sparking meaningful dialogue, and afternoons transitioned into intensely hands-on creative sessions, closing with thoughtful group critiques that deepened our collective understanding.
What sets the IMF experience apart is not only the world-class instruction but also the camaraderie and wisdom shared among fellow master-level designers hailing from across the globe. There was no space for ego—only shared reverence for floristry and a hunger for knowledge, creating a space where the best truly elevated one another. To be counted among the IMF graduates feels like the highest honor, a testament to the profound impact these individuals have on our art form.
The program itself, crafted with the meticulous care and vision of the Boerma family, leaves nothing to chance—every detail, from curriculum to daily rituals, is intentional. Even the meals reflect their dedication: fresh, organic, and nourishing, sustaining both body and soul throughout the journey. I cannot speak more highly of the International Master Florist program—it is a transformative chapter for any designer seeking depth, connection, and excellence within our botanical community.
All the courses from DFD, ADFD and IMF are so worthy of improving your creativity and floristry. They approach you to be the next level. They give you a different task every day and you can learn small details by theory lesson. Warm atmosphere all the time, and they are so friendly! Hope you don’t miss this amazing opportunity!!
