Heidi earned her Doctorate in Clinical Psychology from Wheaton College in 2002 and helped establish and build the Pine Rest Des Moines Clinic, serving thousands of patients in Central Iowa for 16 years. Heidi and her husband, Chad Quist, transitioned the Pine Rest Des Moines Clinic to Heartland Christian Counseling in 2018.
