Steven went to The Maryland Institute, College of Art, in Baltimore, Maryland, USA, where he graduated with a degree in painting, 1976. It was a great education—he loved being in a close-knit art community, experimenting and learning in depth many art disciplines. After he graduated, he headed west and ended up in another art community, Santa Fe, New Mexico. Boone began working in portraiture and eventually, in 1986, opened a studio on Canyon Road, where to sell his paintings. Later, he owned the first STEVEN BOONE GALLERY. Eventually, the name changed to ELAN, and he had taken a partner.

In 1997, Boone's oldest daughter was diagnosed with cancer, and he sold the gallery to devote himself to her healing. She died in 1999 and Steven wrote a book about their journey together in life. It is called A Heart Traced in Sand, and has won several awards.

In 2011, Boone opened the second Steven Boone Gallery on Canyon Road. It stayed open three years. Since then I traveled out of the USA, to Africa and Europe, and around the world for a second time, continuing to paint, photograph and write. In 2015 and 2016 he opened "pop-up" Boone galleries on Santa Fe's historic plaza.

Boone's work is in many private collections across the United States, also in Canada, the United Kingdom, Germany, and Spain. Boone paintings are part of the permanent collection of The Foundation Van Gogh, in Arles, France, and the United States Department of Interior. Various of works have been used for magazines and books.

Steven married artist Amy Córdova in October of 2018. They show their artwork together. In March, 2021, Amy and Steven left the United States to live in Oaxaca, Mexico.

In November, 2023 Steven and Amy had a two person show of their Mexican paintings at Cuatrosiete Galeria in Oaxaca for Dia de Muertos. They are now represented at Cuatrosiete Galeria⏤a premiere downtown Oaxacan gallery.
