Greg is usually seen at Nantucket Cottage Hospital with a stethoscope around his neck. He is a local family physician. He is also an avid landscape photographer. He taught himself to use the camera as his paintbrush and the computer as his canvas, and uses these tools to try and capture the beauty of the island and the magnificent light that bounces off of it.
His stock photography can be seen in numerous local publications, including N Magazine and Cape Cod Life, as well as internationally, represented by Getty Images.
His prints can be seen at the Joyce and Seward Johnson Gallery of the Artists Association of Nantucket.
