Erin Cook

Erin Cook, PsyD, PMH-C, is a psychologist, co-founder, and director of Red Elm Psychotherapy, a specialty practice focused on OCD and perinatal mental health. She is a Certified Perinatal Mental Health Professional through Postpartum Support International and specializes in the assessment and treatment of OCD, anxiety, and perinatal mental health concerns, with particular expertise in perinatal OCD, intrusive thoughts, pregnancy and infant loss, high-risk pregnancy, and birth trauma.

Dr. Cook has specialized clinical experience in Exposure and Response Prevention (ERP) for OCD and draws from Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and attachment-informed and relational approaches. Her work focuses on adapting evidence-based OCD treatment to the unique context of pregnancy, postpartum, and early parenthood, including helping clinicians distinguish common perinatal experiences from clinically significant OCD, anxiety, trauma-related symptoms, and other psychiatric presentations.

She provides clinical education and training for mental health professionals on perinatal mental health and OCD and is particularly interested in improving clinicians’ ability to recognize and appropriately treat OCD and intrusive thoughts during the perinatal period.
