About me

Home in Phnom Pehn

My wife and I decided to relocate permanently to her home in Phnom Penh—a move that has enriched both my personal and professional life. This gives me a distinct advantage: the ability to apply my specialized knowledge within the context of local Khmer culture, ensuring my work is always culturally resonant and impactful.
