Background and approach
His background includes long experience supporting people who face complex emotional patterns and co-occurring difficulties. In sessions he draws from client-centered methods to follow each person's priorities. He also uses Cognitive Behavioral Therapy and Dialectical Behavior Therapy tools to teach practical skills for managing mood, thoughts, and behavior.
Dennis mixes approaches to match what each person needs in the moment. He pays attention to how attachment, abandonment, and communication styles shape relationships. That means he helps people improve how they connect, set boundaries, and handle conflict.
He also supports clients dealing with compassion fatigue and job-related stressors. Dennis aims to keep the work collaborative and goal-focused. He helps people build clearer communication, stronger self-regard, and daily coping tools.
The pace and focus depend on each person's goals and life situation.
Therapeutic approaches and online support
Client-Centered Therapy focuses on listening and following what matters most to the client. The therapist offers empathy and reflection so people can clarify goals and feel understood. Cognitive Behavioral Therapy, or CBT, teaches straightforward skills to spot unhelpful thoughts and change behaviors that keep anxiety or depression going. It is useful for managing panic, worry, sleep problems, and low mood.Finding the right approach is part of the work. The therapist will collaborate with each person to choose or combine methods based on their needs and goals. That collaborative process helps tailor sessions to whether someone wants skill training, deeper exploration, or both.
Online therapy with video calls, phone sessions, live chat, or text-based messaging makes it easier to fit counseling into a busy week. Video lets people work face-to-face when they want that interaction. Phone sessions can be a good option when bandwidth is limited or a shorter check-in is needed. Live chat and text messaging allow for brief updates, skills coaching, and ongoing support between longer sessions. These options give flexibility to keep progress moving despite travel, work, or schedule changes.
