How therapeutic approaches fit into online care

Dennis frequently uses Client-Centered Therapy and Cognitive Behavioral Therapy in his work. Client-centered work focuses on hearing each person without judgment and following their lead to identify what matters most. Cognitive Behavioral Therapy teaches practical tools to spot unhelpful thoughts and change behaviors that keep problems going.

Finding the right approach is part of the work together. He will ask about goals, daily routines, and what has or hasn't helped before, then recommend methods that match those needs. This is a collaborative process and adjustments are made as progress and preferences become clearer.

If you are considering online therapy, confirm the session formats before booking so you know what is offered. Online sessions can make it easier to fit counseling into a busy week, allow shorter check-ins when time is limited, and reduce travel time. Licensed professionals can guide you through skills practice, exposure work, and communication exercises effectively in remote appointments when the approach and format fit your needs.
