01About Dennis

Dennis Siefker is a licensed professional counselor in Colorado with 30 years of clinical experience. He works with adults facing depression, addiction, anxiety, grief, and complicated relationship issues. His practice centers on helping people find practical ways to cope and move forward.

Dennis uses straightforward, people-focused methods rather than jargon. Sessions focus on what is happening now and on skills that can be used between meetings. He pays attention to how past experiences shape present patterns, especially around attachment and intimacy.

Background and approach

Many clients come for help after a major life change or when stress becomes overwhelming. He also supports those dealing with trauma, eating and sleeping problems, ADHD, and compassion fatigue. Dennis addresses both emotional symptoms and everyday challenges like communication and boundary-setting.

His style blends active listening with tools from cognitive behavioral and dialectical behavior approaches. That means identifying unhelpful thoughts, practicing new behaviors, and building emotional regulation skills. He also draws on client-centered and emotionally focused ideas to strengthen connections and self-understanding.

Sessions are offered by video call, phone, live chat, or text messaging to fit different schedules. Pricing varies with location and uses a subscription model that can be canceled at any time. To begin, people complete a short matching questionnaire and then schedule according to therapist availability.

04Online support

Therapeutic approaches applied to online care

Client-centered therapy puts the person's experience first. The therapist listens closely and helps people find their own solutions, which can be useful for building self-trust and clarity about goals.

Cognitive Behavioral Therapy, or CBT, focuses on identifying unhelpful thoughts and testing new behaviors. It is often used for anxiety, depression, and stress when people want clear steps to change how they think and act.

Dialectical Behavior Therapy, or DBT, teaches emotional regulation, distress tolerance, and better interpersonal skills. It can help people who feel overwhelmed by intense emotions or who struggle with relationship patterns.

Finding the right approach is part of the work. The therapist will collaborate with each person to choose or combine methods that match their needs, goals, and preferences. That gives space to adjust the plan as progress is made.

Online sessions are offered by video call, phone, live chat, or text-based messaging for flexibility. Video is useful when visual cues matter, phone can be easier when bandwidth is limited, chat or text fits short check-ins or tight schedules. These options make it simpler to fit therapy into work, school, or caregiving routines while keeping treatment consistent and approachable.
