04Online support
How Mari’s approaches work online
Client-Centered Therapy focuses on listening and building a respectful relationship. In online sessions this means time is spent understanding what matters most to the client and following their pace. Cognitive Behavioral Therapy (CBT) looks at patterns of thinking and behavior and tests small changes. Practically, this can mean setting short homework tasks or trying a new response between video or phone sessions.Finding the right approach is part of the work together. Mari will talk with the client about goals, preferences, and what feels useful. She combines methods and adjusts the plan as progress is made so the client stays involved in decisions.
Online therapy offers flexibility for busy schedules and varying needs. Video calls are useful for in-depth conversations and visual cues. Phone sessions work when bandwidth is limited or a quieter check-in is needed. Live chat and text-based messaging suit brief updates, coaching-style check-ins, or people who prefer writing. These options make it simpler to fit therapy into day-to-day life while focusing on real changes.
