Dena Tollefson is an American artist whose bold contemporary  paintings focus on joyful use of color, texture and movement.

Dena Tollefson (Dena Schaefer), born 1965,  is a full-time,  professional artist.   Tollefson graduated from Iowa State University in 1988 and lived in Dallas Texas before returning to Iowa in 1991 where she developed her unique, highly textured  painting style. She lives in Cedar Rapids, Iowa with her husband and family.

Tollefson is represented in galleries nationally in New Mexico, California, Iowa, Wisconsin and Illinois.

Her "Daubism" body of work is a unique process she developed, where "daubs" of individually mixed  paint are applied with a palette knife. The largest daubs are applied with a serving spoon, allowing ridges of paint which catch the light and appear to dance and scintillate as the viewer moves past the painting. Tollefson’s work focuses on botanicals, ponds, skies, and her Corn Series of work, biographies where people are depicted as ears of corn. Her work is highly tactile.
