Dennis Doheny is a third generation Californian, born and raised in the Los Angeles area and currently residing in Santa Barbara. Growing up with an innate love of art, he spent much of his childhood drawing and painting. Although he studied some art in school, Doheny is largely self-taught. After graduating from Pacific Palisades High School in 1974, he exhibited with Peterson Gallery of Beverly Hills under the direction of Jean Stern. From 1986 until 1996, Doheny supported his family with a steady career in commercial art until his passion for painting prevailed.

Since 1996, Doheny's fine art career has developed a strong following both locally and nationally. Collectors are drawn to his beautiful renderings of the western landscape. Doheny was honored in September of 2006 with the inaugural purchase prize at the Eiteljorg Museum’s Quest for the West exhibition. In addition, upon his first showing at the Prix de West Invitational Art Exhibition in June of 2006, Dennis won the prestigious Frederic Remington Award, given in recognition for exceptional artistic merit for a painting, and won it again in June of 2008. In 2003 he was honored by the Autry National Center with the Masters of the American West Award and his painting was acquired by the museum for its permanent collection. He received the Granville Redmond Memorial Purchase Prize in 2000 for his painting New Dawn at the first annual Spring Salon of the future California Art Academy and Museum in Pasadena, California. At the beginning of his return to fine art in 1998, he was awarded First Place in the Carmel Plein Air Painting Competition.

Dennis Doheny is a Signature Member of the California Art Club.
