Karen Eastman Everhart spent most of her weekends and summers as a youngster on a small farm in southeast Kansas.  There were always horses present to assist with working cattle and wherever the horses were, there, too, was Karen.  Her passion for horses never died despite the distractions of high school, college, career and family.  In 1981 Karen purchased her first horse, a Palomino mare she named Rainbow.  Twenty-five years later Rainbow resides at Rainbow Meadows Equine Rescue and Retirement, Inc.  At 31 years of age, she is the matriarch of the horses in Karen's herd.

Karen's post-graduate educational studies focused on exercise and wellness.  She spent the majority of her professional career in health care as a medical administrator and was a part-time fitness instructor for over 28 years.  In 2000, Karen founded Horse Calls, LLC, a program of equine management consultation, Centered Riding instruction, and horse training.

Her love for horses led her into Competitive Trail Riding.  She has successfully competed in distance events sanctioned by the North American Trail Riding Congress (NATRC) and the Arabian Horse Association (AHA). 

In late 2005, Karen and her husband, David, founded Rainbow Meadows Equine Rescue and Retirement, Inc. as a facility for abused, neglected or abandoned horses as well as sponsored retired horses.
