How Dennis blends practical therapy with online care

CBT, or cognitive behavioral therapy, helps people notice and change unhelpful thoughts and behaviors. It is often used for anxiety, depression, sleep and eating problems, and managing daily stress. Client-centered therapy focuses on listening, empathy, and helping people find their own answers; it can be useful when someone needs support building self-esteem or sorting out values.

Dennis often combines these approaches with DBT skills when emotional regulation and distress tolerance are needed. Finding the right mix is a collaborative process. The therapist and client will discuss goals, try approaches, and adjust what they do based on results and personal preference.

Online formats include video calls, phone sessions, live chat, and text-based messaging to fit different schedules and needs. Video is good for full conversations and working through skills together. Phone sessions can be a lighter option when bandwidth or camera use is difficult. Live chat or messaging can work for quick check-ins, in-the-moment support, or ongoing skill practice between sessions. These options make it easier to fit therapy into a busy life and to continue progress even when in-person visits are not possible.
