Addiction therapists & psychiatrists in New York

Diana Lankenau has a Master of Science in Nursing from Florida State University and Chamberlain University. She has a Bachelor's in nursing from University of Miami. BA in Psychology from Florida International University. She is Board Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-BC).

I conduct therapy sessions in both English and Spanish. I have experience working with individuals facing challenges related to depression and/or anxiety, as well as those with a history of self-harm and suicidal ideation. I also work with clients to heal from sexual abuse, intimate partner violence, intergenerational trauma, and racial trauma.

My therapeutic approach is rooted in somatic psychotherapy, which acknowledges the mind-body connection and the ways stress is held in the body. As a first-generation Mexican, I am deeply passionate about supporting BIPOC individuals and those from immigrant families.

Additionally, I have a strong background in working with individuals who engage in problematic sexual behavior, as well as those seeking to address an unhealthy relationship with alcohol and drugs.

Clients often describe me as warm, thoughtful, and direct. I aim to create a space where you feel understood and supported, while also gently challenged to grow. I believe therapy should feel collaborative, not judgmental, not passive, and not surface-level.

Welcome! I approach my work with clients from a relational, evidence-based perspective; while I want to use research-based interventions to help you in your therapy journey, I also recognize the importance of the therapeutic relationship itself. The space I try to build with clients is warm, supportive, humorous, and actively engaging. I see clients for both short and long term therapeutic interventions depending on need.

Everyone deserves a meaningful life, though growth often requires intention and support. I’m David Coen, Licensed Mental Health Counselor, and I work with adults navigating anxiety, depression, trauma, life transitions, and challenges related to self-worth or direction. While I support clients across many backgrounds and professions, I have particular appreciation for those in creative fields—such as writers, designers, and visual artists—who may experience heightened sensitivity, self-criticism, or pressure tied to performance and originality.
