Keir studied fine art at California State University at Northridge, and painted his first mural at the age of 18. He found the immense standing of the social impact and the profound community involvement an ideal way to express creative ideals to a broader reaching audience. Becoming an advocate on many social issues and community groups, he has worked collaboratively in the production of murals with life inmates at state penitentiaries, elderly, college students, youth in detention centers, elementary and high school students, mentally, and physically disabled and the general public through teaching workshops.
