Sanborn's father was the head of exhibitions at the Library of Congress, and his mother was a concert pianist and photo researcher. He grew up in Alexandria and Arlington, Virginia, attending JEB Stuart High School in Fairfax, and then attended Randolph-Macon College, receiving a degree in paleontology, fine arts, and social anthropology in 1968, followed by a Master of Fine Arts degree in sculpture from the Pratt Institute in 1971. He taught at Montgomery College in Rockville, Maryland, and then for nine years was the artist-in-residence at Glen Echo Park.
His artwork has been displayed at High Museum of Art, the Los Angeles County Museum of Art, the Corcoran Gallery of Art, and the Hirshhorn Museum and Sculpture Garden. He has created sculptural works for the Massachusetts Institute of Technology, the Central Intelligence Agency, and the National Oceanic and Atmospheric Administration. Themes in his work have included "making the invisible visible", with many sculptures focusing on topics such as magnetism, the coriolis effect, secret messages, and mysteries of atomic reactions.
