Expert ERP + Compassionate Perinatal Care for Adults & Families
Dr. Niles Cook, PsyD
Co-Founder & Clinical Director
Dr. Niles Cook is co-founder and clinical director of Red Elm Psychotherapy, where he specializes in the treatment of obsessive-compulsive disorder (OCD) and anxiety disorders using Exposure and Response Prevention (ERP).
His work focuses on helping people break free from cycles of intrusive thoughts, uncertainty, and compulsive behaviors that reinforce OCD over time. He works with a range of OCD presentations, including harm OCD, scrupulosity, relationship OCD, health anxiety, and other forms of obsessional doubt.
Niles takes a collaborative, direct, and compassionate approach to ERP. Treatment is not about eliminating unwanted thoughts or achieving certainty; instead, he helps clients build the skills and confidence to stop organizing their lives around OCD and move toward what matters to them.
As clinical director, Niles brings extensive experience in clinical training and education to Red Elm. He has taught doctoral psychology students, supervised clinicians in Exposure and Response Prevention (ERP), and led a psychology practicum training program at the Portland Anxiety Clinic. He has also developed and taught doctoral-level coursework in basic clinical skills, diagnosis, and treatment planning. This experience informs how he approaches clinical care and the development of Red Elm's clinical model, including how clinicians are trained and supported in providing specialized OCD treatment.
He continues to maintain an active clinical practice, working directly with clients while helping shape the clinical direction of Red Elm.
Where He Works With Clients
Niles provides therapy in Virginia and through secure telehealth in eligible PSYPACT states.

Dr. Amber Morris is a clinical psychologist specializing in perinatal mental health, OCD, and trauma-related concerns. She works with women during pregnancy, postpartum, and the transition into parenthood, including those experiencing intrusive thoughts, anxiety, OCD, traumatic experiences, and the emotional challenges that can accompany major life transitions.
