Stephen Seymour developed an interest in art at an early age. He started painting and drawing as a child and while in high school painted every day. He attended summer classes at the Art Institute in Pasadena and the Parsons School of Design at the New School Social Research in NYC.  After school he spent time designing textiles. In 2017 he retired from FedEx as the Managing Director of Operation for Northern California and Hawaii after 32 years and began to paint fulltime.

In 2018 he was appointed to the San Mateo County Arts Commission by Supervisor David Pine. In 2021 he was introduced to Ruth Waters and together with the help of Peter Cleaveland, they started the Peninsula Art Foundation. The Foundation supports individual artists and arts organizations in San Mateo County. They provide artist studios, gallery space, and learning centers at the Tanforan Mall in San Bruno. Stephen also manages the Visual Arts Exhibit at the San Mateo County Fair.

His paintings are influenced by his travels having spent time in San Miguel de Allende & Oaxaca in Mexico and Antigua and Lake Atitlan Guatemala. Both Mexico and Guatemala are rich in culture, color, and texture. The brushstrokes and vibrant colors employed in his painting reflect the flavor of these two countries.
