Therapeutic approaches and online care

Client-Centered Therapy focuses on understanding each person from their own perspective. In practice this means the therapist creates a supportive, nonjudgmental space and helps clients explore their feelings and values so they can make choices that fit their life.

Cognitive Behavioral Therapy (CBT) looks at the links between thoughts, feelings, and behaviors. It offers practical strategies to identify unhelpful thinking patterns and develop new skills that reduce symptoms of anxiety, depression, and other concerns.

Dialectical Behavior Therapy (DBT) teaches concrete skills for regulating emotions, tolerating distress, and improving interpersonal effectiveness. It can be especially useful for people who struggle with intense emotions or relationship conflicts.

Finding the right approach is part of the work. Dennis collaborates with each person to determine which methods fit their goals, needs, and preferences, adjusting the plan as progress unfolds.

Online therapy offers flexibility and easier access to care. Licensed professionals and therapists can meet via video calls, phone sessions, live chat, or text-based messaging, making it simpler to fit sessions into busy schedules, maintain continuity during life changes, and receive support from wherever the client is located in Colorado.
