I have 40 years of experience, and specialize in the field of Asian art with specific knowledge in the areas of valuation, appraisal and documentation. I have published on such topics as appraising Asian art and the origins and manufacture of Chinese snuff bottles. I have testified on expert Asian art witness. I vetted at the International Asian Art Fair in New York City for ten years as an expert in the fields of Chinese and South Asian art. This is to authenticate objects that are for sale by major dealers from around the world.
