Christopher Xavier O'Hare is an American artist, with extensive interests in engineering and marine biology. Since 1988 his architectural sculpture works have been commissioned by over twenty-four thousand architects on over two hundred and fifty thousand projects throughout the entire United States and as far off as Japan and the Middle East. Specializing in the medium of cast stone, he has developed a thorough understanding of limestone cement and the latest technologies in concrete and stone fabrication. He brings that knowledge to creating state-of-the-art artificial reef modules.
O’Hare’s understanding of biological systems, engineering, art and industrial processing gives him a unique ability to develop, design and build the many reef modules, habitats and restoration devices offered by Reef Cells. He holds numerous patents in the field of marine restoration and enhancement.
Originally trained as an Architect/Engineer and later a Landscape Architect, O'Hare switched careers after years of designing commercial and private gardens to devote his full attention to architectural art. After years of studying art throughout Europe, South America and Asia, he founded Pineapple Grove Designs in Delray Beach Florida in 1988 and offered his work to architects and clients throughout the world. O'Hare's body of work includes commissions by most departments and agencies of the Federal Government in addition to State, Municipal and Institutional clients. More recently, his work has expanded to include sculptural elements intended to be submerged as part of artificial reefs – see CXOART.com
O'Hare's concern for environmental issues led him to a parallel career in bio-marine enhancement. He founded Reef Cells and later, 1000 Mermaids and Ocean Rescue Alliance. The later two were divested to other people so O’Hare could focus solely on Reef Cells.
O’Hare continues to work with scientists and other stakeholders in the marine restoration field to develop new devices and methods to protect, preserve, restore and create marine ecosystems.
