Heidi Vermeer-Quist, PsyD
Clinical Director and Lead Clinician

Dr. Heidi Vermeer-Quist is a licensed clinical psychologist with over 20 years of clinical, teaching and consulting experience. One of her core passions is to serve the Christian church with best practices of psychology.  

 

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. She has provided psychological assessment and psychotherapy to people struggling with depression, anxiety, relational conflicts, trauma recovery, unresolved grief and adjustment, and personality disorders. In addition to her clinical training, Heidi also has obtained specialized training and extensive experience in Organizational Psychology and Family Business Governance. She has served Vermeer Corporation in various family governance roles, including serving on the Board of Directors. She continues to provide clinical services through Heartland Christian Counseling, as well as, family business and organizational consulting services through www.vqconsult.com. Heidi currently serves on the Iowa Board of Professional Psychology. 

 

Heidi recently released the first two books of a three-book personal growth series called Gardening Your Life. The first book, Grounding, and the second book, Grieving, are workbooks (ideal for small groups) that integrate the best practices of the field of psychology with solid Christian teaching. 

 

Personally, Heidi enjoys singing, raising their three amazing kids with Chad, and participating in the joy of each God given moment (though she is still learning how to do this!).
