Carol and Harvey were pillars of the Longmont community and mentored others to community service, a legacy Carol continues. Carol was one of the developers of Meadow Green Farm, a thoroughbred training center. The Yoakums developed Raspberry Hill Business Park where Stevinson Lexus, Stapp Toyota, and other businesses are located today. The Yoakums were active in philanthropic endeavors in many states. Carol was one of the signers when the Longmont United Hospital Foundation was formed. They founded programs at the Ellsworth Correctional Facility in Kansas and carpeted the Spiritual Life Center there. In Pauls Valley, Okla., the couple started a 32-bed drug and alcohol treatment facility which was later sold to the Chickasaw Nation and is now an adolescent treatment facility.
