Nancy Niefield started "throwing" on the potter's wheel in 1968 when she was studying art education at Douglass College (Rutgers University, New Jersey). She received a master's degree in studio art from University of Minnesota. She has taught art and pottery to every age group. She taught Ceramics at Union College in Schenectady, New York from 1999 to 2016.

In 1988 she opened TWO SPRUCE POTTERY, her studio and sales gallery in Schenectady, New York.

In 2010 the retail gallery was closed and the studio was moved to Nancy's home in Charlton, New York and later to Saratoga Springs, New York.
