Katherine O'Sullivan

Katherine O'Sullivan is a Licensed Clinical Social Worker (LCSW) in New York with 15 years of professional experience. She works with people facing stress, anxiety, low self-esteem, depression, and coping with major life changes. Katherine also addresses compassion fatigue and a range of related concerns including caregiver stress, communication problems, and questions about life purpose.

She helps people who feel stuck find clearer footing through straightforward conversation and practical steps. Sessions focus on identifying patterns that keep someone feeling overwhelmed and testing small changes that can alter daily life. Katherine draws on evidence-based therapeutic techniques to guide that work without promising quick fixes.

Her background includes individual, group, and family work, and she has spent considerable time supporting teens and young adults as they navigate transitions. She explains options plainly and adjusts conversation to match what each person brings to a session.

Katherine pays attention to emotional blocks like guilt, shame, and control issues, and she helps clients address isolation, social anxiety, and panic symptoms. She also works with women’s issues and supports people dealing with forgiveness and self-love struggles.

Practical steps and regular check-ins are central to her approach. People can expect focused conversations that aim to clarify what matters next, set small goals, and track how changes feel in real life.

Practical evidence-based approaches for online work

Two common evidence-based approaches she uses are cognitive techniques that look at how thoughts affect feeling and behavior, and behavioral strategies that test small changes to routines. Cognitive techniques help identify unhelpful thinking patterns that feed anxiety or low self-esteem. Behavioral strategies focus on setting tiny, achievable steps to see what changes feel different in everyday life.

Another useful approach is structured problem-solving, which breaks big, vague concerns into specific choices and actions. This helps when someone is unsure what comes next or feels overwhelmed by options. These methods are explained plainly and practiced together so the client can notice what helps between sessions.

Finding the right mix of methods is part of the work. Katherine will collaborate with each person to choose techniques that fit their goals, needs, and preferences. She frames sessions as a shared process of testing what works rather than promising a single fixed method.

Confirm current session formats before booking so you know what is offered. Online sessions can make it easier to fit therapy into a busy day, reduce travel time, and allow for shorter check-ins when needed. Some formats may also require less bandwidth or no camera, which can help people who prefer shorter or lower-tech sessions.
