How Dennis Uses Talk, Skills, and Focused Methods Online
Client-Centered Therapy puts the person's concerns front and center. The therapist listens, reflects, and helps clients decide what matters most. This approach supports people who need space to tell their story and set personal goals.Cognitive Behavioral Therapy, or CBT, looks at thoughts and behaviors that keep problems going. It offers concrete exercises and experiments to change unhelpful thinking and build better habits. CBT can be useful for anxiety, depression, sleep and eating issues, and stress management.
Dialectical Behavior Therapy, DBT, teaches skills for regulating intense emotions and improving communication. It emphasizes practicing techniques like distress tolerance and mindfulness to reduce impulsive reactions and improve relationships.
Finding the right mix of approaches is part of the early work together. The therapist will collaborate with each person to choose methods that match goals, needs, and preferences, and will adjust the plan as progress happens.
Online sessions are offered by video calls, phone, live chat, or text-based messaging to fit different schedules and needs. Video is good for face-to-face conversation and skill modeling. Phone sessions work well when bandwidth is limited or a simpler check-in is needed. Live chat and text messaging let people stay connected between meetings and use shorter check-ins on busy days. These options make it easier to keep therapy consistent during life transitions.
