Born in Rutherford County, North Carolina to fundamentalist Christian parents, he came out to his parents at age 17 must to their horror. He received his Bachelor of Arts degree in psychology at the University of North Carolina at Chapel Hill where he also belonged to the Carolina Gay Association. He became a sex educator on campus as an openly gay man,
speaking to various campus and non-campus organizations about gay issues.
Kimeron then completed a Master's degree in Clinical Psychology at Western Carolina University in 1986 where he was a founder and charter member of the first lesbian and gay student group called "Lavender Bridges". He then received his Ph.D. in Clinical Psychology in 1990 from the University of Southern Mississippi where he was the first openly gay doctoral student in the department.
Returned to Duke University Medical Center for his internship where he was a
member of the Duke Lesbian and Gay Graduate Student organization. While completing the internship, Kimeron began volunteering at the Durham Gay Men's Health Project as a support group leader for people living with HIV.
In 1990, Kimeron taught at Appalachian State University as one of only a handful of openly gay faculty and co-led the only HIV/AIDS support group within 100 miles of the university at the time. While there, he also helped found the first community LGBT organization that thrived despite threats of violence from anonymous callers.
He is now the Director of the Bay Area Pain Program in Los Gatos and San Jose, California. Although Kimeron went on to develop a subspecialty within the clinical practice in the area of pain management and health psychology, he has continued to try to support the GLBT community through his writings which have included The Gay and Lesbian Self-Esteem Book: A Guide to Loving Ourselves and Queer Blues: The Lesbian and Gay Guide to Overcoming Depression, as well as GLBT book reviews, articles and workshops.
