Romero began making pottery in 1919 and continued through her 100th birthday. She is credited with helping to keep the micaceous pottery tradition alive at Taos Pueblo. In 2012 she was honored with a roadside marker in Taos describing her commitment to keeping the pottery art alive.

Her pieces found their way into private collections and museums such as the Los Angeles County Museum, the Southwest Museum of the American, the School of American Research, the Millicent Rogers Museum in Taos and the Museum of Indian Arts and Culture in Santa Fe.
