Cassandra Duff, LMHC

Cassandra Duff is a licensed mental health counselor who focuses on thoughts and everyday habits that shape how people feel and act. She draws on client-centered methods to create conversations that are respectful and grounded in each person's experience. Cassandra aims to help people reduce stress, manage anxiety, and navigate relationship and anger challenges in practical ways.

She has nearly two decades of experience as an LMHC in New York and has worked with people facing depression, bipolar concerns, addictions, and intimacy-related issues. Her approach is collaborative - she listens first, then tailors the work to what each person needs. Many clients come for help with life changes, career questions, or ADHD-related struggles, and she brings straightforward strategies to those concerns.

Cassandra also supports people dealing with caregiver stress, commitment doubts, and family problems. She addresses feelings like guilt, shame, isolation, jealousy, and issues around infidelity in a direct, nonjudgmental way. Financial stress and multicultural concerns are part of her broader practice.

In sessions she uses practical tools drawn from cognitive behavioral ideas and skills-based techniques from dialectical behavior therapy alongside a client-centered stance. That mix helps people spot unhelpful thoughts and build new daily habits. Cassandra frames therapy as a step-by-step process toward clearer thinking and steadier routines.

She works in English and practices in New York. Starting therapy with her begins by completing a short matching questionnaire and scheduling according to availability.

Approaches that guide online work

Cognitive Behavioral Therapy helps people notice and change thought patterns that lead to distress. It breaks problems into small steps and gives concrete skills to test in daily life, which can help with anxiety, depression, and habits that feel stuck.

Dialectical Behavior Therapy focuses on building skills for emotion regulation, distress tolerance, and interpersonal effectiveness. It offers short, practical techniques people can use during heated moments or when relationships feel strained.

Client-Centered Therapy emphasizes listening and tailoring conversations to each person’s needs. The therapist follows the client's lead and supports them in finding their own answers rather than imposing a fixed plan.

Finding the right mix of approaches is part of the work. Cassandra will collaborate with each person to identify which methods fit their goals and preferences, adjusting the plan as progress is made.

Confirm which online formats are available before booking, since session types are not listed in the biography. Online sessions can make it easier to fit therapy into a busy week - for example by reducing travel time, allowing shorter check-ins during breaks, or letting people choose whether to use video or audio when those options exist. Talk with the therapist about practical needs so sessions can be scheduled to fit everyday life.
