About Dennis
Dennis Siefker is a Licensed Professional Counselor with 30 years of clinical experience in Colorado. He focuses on helping people manage depression, anxiety, addiction, and relationship struggles. He works with adults who want practical tools and steady support during hard times.
Dennis uses straightforward conversation and careful listening to understand what matters most to each person. He helps clients name patterns that get in the way, learn skills to cope with stress, and set achievable goals.
Background and approach
Sessions aim to be practical and focused on day-to-day changes. He draws from several therapy approaches to match what a person needs. That might mean looking at thoughts and behaviors, practicing emotion regulation skills, or exploring attachment patterns that affect relationships.
The pace and methods are adjusted to each person's situation. Dennis pays attention to issues like grief, trauma, parenting strain, work stress, and challenges tied to identity or neurodiversity. He also offers support for intimacy, body image, and coping after major life changes.
His style is calm, direct, and rooted in real-world problem solving. Many clients come for help with improving communication, managing anger, or reducing compulsive behaviors tied to addiction or eating. Dennis aims to build practical plans people can use outside sessions.
He encourages steady progress and checks in about what’s working and what needs to change.
How therapeutic approaches adapt to online care
Client-Centered Therapy emphasizes listening and building a strong therapeutic relationship. It focuses on the client’s experience and supports people as they find their own answers, which can help with depression, low self-esteem, and feeling stuck. Cognitive Behavioral Therapy, or CBT, looks at how thoughts, feelings, and actions connect and teaches practical skills to reduce anxiety, manage mood, and change unhelpful behavior. Dialectical Behavior Therapy, DBT, adds emotion regulation and distress-tolerance skills that are useful for intense emotions, stress, and difficulties with impulse control.Finding the right approach is a collaborative process. The therapist will discuss goals, try strategies, and adjust methods based on what helps most. Clients and the therapist work together to choose techniques that match needs, values, and daily life demands.
Online sessions use video calls, phone sessions, live chat, or text-based messaging to make therapy more flexible. Video is useful for deeper conversational work and skills practice. Phone sessions are a good option when bandwidth is limited or when a shorter check-in fits the schedule. Live chat or text-based messaging can support quick reflections, brief coaching, and ongoing tracking between sessions. These options help therapy fit around work, caregiving, and travel while keeping focus on progress and practical tools.
