In 1992 Rey Alfonso left Cuba and settled in San Francisco. Over the next six years Alfonso labored to become proficient in the metal world by working with both sculptors and metal craftsmen to attain an exhaustive knowledge of metal design and fabrication. His talent and ideas were quickly recognized and several of his public works and sculptural signs remain visible in San Francisco. It was his work with aluminum on a large scale commission that first intrigued and later obsessed Alfonso as he developed his present style. Today Alfonso’s work can be found in collections in more than 40 countries. He has created works for individuals and organizations ranging from the San Francisco Opera House to the Mayo Clinic. In 2010, he was commissioned by Hilton Worldwide to create over 150 works for the private collections of the company’s owners and investors.
