Our Treatment Focus


Dialectical Behavior Therapy (DBT) is effective in treating a wide range of DSM-5 disorders.

DBT is a specialized type of Cognitive Behavior Therapy (CBT).

DBT was originally developed by Marsha Linehan, PhD, to treat chronically suicidal individuals diagnosed with Borderline Personality Disorder (BPD). It is now recognized as the gold standard psychological treatment for this population. However,  research has proven that it is effective in treating a wide range of other disorders such as substance dependence, depression, mood disorders, post-traumatic stress disorder (PTSD), and eating disorders.

The goal of DBT is to help individuals build a life that they feel is worth living. In DBT, the client and the therapist work together to set goals . It is the collaboration that helps treatment to be  meaningful. Usually, this means they work on ways to decrease maladaptive behaviors and replace them with effective, life-enhancing behaviors.  DBT has five components that work together to make up a standard DBT program. 

Comprehensive DBT offers several modalities of treatment including individual psychotherapy, between session skills phone coaching, DBT skills training, case management, team consultation.  This is different than many other psychotherapies that consist of just one mode of treatment (such as individual therapy).  Each component or mode of treatment is intended to meet a specific function. Functions or objectives of DBT are to enhance the clients capabilities, increase motivation, ensure they generalize the skills through skills coaching and assure therapist are consulting other DBT therapist to support the treatment goals and  adherence to the treatment model. 

Consultation for treatment options

Maybe you don't think you need a specialized DBT treatment?   More traditional CBT is also available. Treatment can be tailored to an individual’s needs which would be determined at the end of the consultation evaluation.  More traditional CBT is also offered depending on the client’s needs. The consultation evaluations allows for the individual to meet and discuss their treatment needs and personal history. It also allows for orientation to the treatment and treatment recommendations based on the information provided. Those who come in for a consultation, do not have to decide by  the end of session, how they would like to proceed. Instead, they will be given written material to review before beginning treatment.   We will be there for you every step of your journey. Our goal is to help you grow from your struggles, heal from your pain, and move forward to where you want to be in  life.

Her private practice opened in 2002, while also on staff at NYPH, offering DBT/CBT to adults suffering from complex and multiple diagnoses.   After more than two decades as a psychotherapist, she is categorized as an expert in treating complex and multiple diagnoses, including BPD but not limited to BPD.  Dena has also completed intensive training in prolonged exposure, DBT-PE, for those who suffer from PTSD.  She specializes in treating young adults, though all adults are welcome.

Expertise in treating Borderline Personality Disorder (BPD), Bipolar Disorder, Major Depression, Anxiety Disorders, Eating Disorders, Substance Dependance and PTSD

Many individuals experience symptoms associated with painful diagnoses and traumatic events.  Anxiety, irritability, and hopelessness can linger and cause difficulty in daily functioning long after the trauma.   Suffering with a mental illness is also incredibly difficult and isolating.  

Treatment can help decrease unwanted negative emotions and  eliminate symptoms that interfere with daily life and the process of  healing,  

Sadness, fear and shame are some of the most common and uncomfortable emotions that disrupt the ability to live in the present. Through evidence based treatment, we are able to help you recover motivation, gain perspective, and acquire effective coping strategies.    Building resistance to excessive negative emotions and living a life without suffering can be achieved! 



Couples and Family Therapy

Relationships are often effected when a person is struggling with emotions and behavioral issues.   Miscommunications,  and  misunderstandings are very common.  Couples treatment allows the therapist to identify points of conflict, in a supportive setting.  In this safe space, we encourage healthy emotional labeling and gentle expression.  It may be beneficial in all stages of the relationship. The focus is to effectively discuss issues and solutions throughout the relationship.       Family members are also welcome  when they need coping skills and support.
