How his approaches translate to online work
Client-Centered Therapy focuses on building a respectful, accepting relationship and listening closely to what matters most to the client. This approach helps people who need space to talk through feelings and make their own choices about change.Cognitive Behavioral Therapy (CBT) offers practical techniques to change unhelpful thoughts and behaviors. It is often used for anxiety, depression, compulsive behaviors, and problems like sleep or eating difficulties.
Dialectical Behavior Therapy (DBT) provides skills for managing intense emotions and improving interpersonal effectiveness. It can be useful when emotional regulation and strong reactions get in the way of daily life.
Finding the right method is part of the work together. The therapist will help clients choose and adjust approaches based on their needs, goals, and what feels doable. That collaborative process includes trying tools and checking what helps most.
If you are considering online sessions, confirm the available session formats before booking. Online work can make it easier to fit therapy into a busy week, reduce travel time, and allow brief check-ins when needed. Ask about scheduling options and how sessions are typically structured so they match your routine.
