Michael Mitsunaga, the current President and CEO of Nunzia Pharmaceutical (previously known as Arizona Gold and Onyx Mining Company), has a wealth of international and public company business experience. As a true entrepreneur at heart, Mitsunaga began in the real estate industry after college. While in the real estate business, he became known for his creative financing skills. His knowledge of financing allowed him to branch out to a myriad of business dealings in Asia and the Pacific. When he was the President of North America for Union Pacific Foods he built sales to millions of dollars a year. After continued success in this industry, he returned to his entrepreneurial heart and started two companies: TSM Recovery, Inc. (a thriving medical waste company) and Automatic Medical Technologies Company (which owns the rights to a patented blood thinner warmer). While he continues to operate those companies, he has most recently taken over the management of Nunzia Pharmaceutical.
