Dr. Dardeen has been in practice working with people to improve their lives since 2002. She is a certified insomnia specialist and enjoys helping people improve their sleep. She has an additional credential in managing critical incidents and responds to traumatic events that impact our area first responders.  Dr. Dardeen has extensive training in Cognitive Processing Therapy and EMDR for Trauma and focuses her practice on treating first responders.  

Dr. Dardeen’s philosophy is that ongoing exposure to trauma causes predictable responses, and we need to train and equip our first responders to recognize and respond positively to these experiences. Traum exposure is normal, carrying it with you for a lifetime is not.  Asking for help managing this is the same as going to your medical doctor when you are sick.  Creating a strong foundation of wellness and understanding trauma's impact on their lives is critical to keeping our first responders healthy.

Dr. Dardeen attended Indiana State University in Terre Haute, Indiana for her undergraduate and graduate training and completed her residency at the Salt Lake City Veteran’s Health Care System in Utah. Dr. Dardeen and her husband have lived in several states throughout the US and enjoy travel, nature, and spending time with their two little boys.
