Originally from New Zealand, Si now resides full-time on mainland China and was WMA Canada's first instructor from Asia. Si has taught WMA courses in Thailand, Malaysia, Hong Kong, and throughout China (and Canada too). He might be the first WMA instructor to have taught on isolated pristine white sand beaches on the Indian Ocean (Gulf of Thailand). Besides teaching wilderness first aid, Si is a professional rock climbing guide and the owner and manager for Insight Adventures. Insight Adventures sprung from China Climb which was China's leading rock climbing and adventure company and WMA's first client in mainland China.
