About Cassandra

Cassandra Duff is a Licensed Mental Health Counselor (LMHC) in New York with 19 years of clinical experience. She works with adults who are managing stress, anxiety, relationship strain, anger, depression, and addiction concerns. Sessions focus on practical skills and clearer thinking rather than long theory talks.

Her approach blends client-centered work with cognitive behavioral strategies and elements of dialectical behavior therapy. That means conversations start where the person is, then move toward specific tools to recognize patterns, reduce overwhelm, and change unhelpful habits. Cassandra helps people spot triggers and develop new responses they can use in daily life.

She often helps clients worried about intimacy, commitment, or career stresses. Other topics she addresses include ADHD, bipolar concerns, coping with life changes, and issues tied to caregiving, money, jealousy, or isolation. She also works with people facing multicultural stress, prejudice, or shame.

In session she leans on straightforward techniques from CBT and DBT alongside a client-centered stance. Expect clear, step-by-step strategies for managing intense feelings, and space to talk through what’s behind those reactions. The goal is more usable coping skills and fewer moments of losing control.

Cassandra practices in New York and carries the LMHC credential. Sessions proceed with a focus on skills, understanding, and practical next steps rather than labels or abstract explanations.

Therapeutic approaches and how they work online

Client-centered therapy focuses on listening and understanding the person’s experience. The therapist follows the client’s concerns and builds practical next steps from there. Cognitive Behavioral Therapy, or CBT, looks at thoughts and behaviors and offers specific exercises to reduce anxiety, anger, and unhelpful patterns. Dialectical Behavior Therapy, or DBT, teaches skills for managing intense emotions, tolerating distress, and improving interpersonal effectiveness.

Choosing the best approach is a collaborative process. Cassandra will talk with the client about goals, daily challenges, and what has or hasn’t helped before. Together they decide which tools to try first and adjust as progress is made. The therapist’s role is to guide, coach, and practice skills with the client rather than impose a single method.

Session formats and scheduling should be confirmed before booking, as current options are not listed here. In general, online sessions can make it easier to fit appointments into workdays, reduce travel time, and allow for shorter check-ins when needed. If a client prefers fewer visual demands they can discuss alternatives that use less bandwidth or a briefer session structure. Ask about exact session options when you start the matching process so arrangements fit everyday life.
