How evidence-based techniques translate to online sessions

Matthew uses evidence-based therapeutic techniques to help people manage anxiety and addiction. Cognitive-behavioral strategies focus on identifying unhelpful thoughts and testing new behaviors to reduce panic, social anxiety, and avoidance. These approaches break problems into specific skills you can practice between sessions. Motivational techniques address readiness to change and help people find small, realistic steps when dealing with substance use, process addictions, or smoking and vaping cessation.

Choosing the right approach is part of the work. Matthew will collaborate with each person to decide which techniques fit their goals and preferences. He listens to current concerns and suggests practical tools, then adjusts the approach based on what helps most in follow-up meetings.

Confirm the session formats before booking since the biography does not list specific options. Online sessions can make it easier to fit therapy into a busy schedule, reduce travel time, and allow shorter check-ins when needed. Phone sessions often use less bandwidth and can be a simpler step than video, while video sessions allow face-to-face conversation and visual cues. Discussing which format works best is part of the first meeting so sessions can fit into daily life.
