Professional statement

Diane Brennan is a Licensed Mental Health Counselor in Midtown, Manhattan. She specializes in grief and has extensive experience offering short-term support for young adults. The majority of her clients are professionals in their 20s or 30s who are navigating a first-time loss. Many individuals who come to Diane want to work through existential issues and ultimately find a way to heal.

Diane’s sessions are client-centered in that she invites her clients to give their opinion and guide sessions. She uses an eclectic combination of modalities, drawing on cognitive-based therapies, a narrative approach, and constructivist approaches. She is also experienced in facilitating creative expression in the therapy room, including through art, music, and guided meditation. Diane knows that grief is such a unique process, so she strives to create an individualized treatment plan that works for the individual she is treating.

Treatment approaches

Cognitive Behavioral Therapy (CBT)In cognitive behavioral therapy, you work with a therapist in a structured way, attending a limited number of sessions. Cognitive behavioral therapy helps you become aware of inaccurate or negative thinking, so you can view challenging situations more clearly and respond to them in a more effective way. (learn more)
Interpersonal Therapy (IPT)Interpersonal Therapy (IPT) is a time-limited psychotherapy that focuses on interpersonal issues, which are understood to be a factor in the genesis and maintenance of psychological distress. The targets of IPT are symptom resolution, improved interpersonal functioning, and increased social support. (learn more)
Mindfulness PracticesMindfulness practices include but are not limited to developing awareness, attention, and remembering. In mindfulness-informed therapy, clients develop tools to become aware of what is occurring within and around them, so they can begin to untangle from mental preoccupations and difficult emotions. Self-acceptance and compassion are also core elements of mindfulness-informed therapy. (learn more)
Supportive TherapySupportive psychotherapy is used primarily to reinforce a patient’s ability to cope with stressors by giving clients the opportunity to express their feelings and thoughts about the issues. Clinicians help patients learn how to move forward and make decisions or changes that may be necessary to adapt, either to an acute change, such as the loss of a loved one or severe disappointment, or to a chronic situation, such as an ongoing illness.
