About Dennis
Dennis Siefker is a Licensed Professional Counselor (LPC) in Colorado with 30 years of clinical experience. He works with adults facing depression, anxiety, addiction, trauma, relationship and family concerns, and other life changes. Sessions focus on practical steps rather than abstract theories.
He uses conversational, goal-focused work to help people clarify what matters and reduce immediate distress. That can mean learning skills to manage strong emotions, changing unhelpful thinking, or finding better ways to talk about difficult topics. He draws on several approaches to match the issue at hand.
Many people come for help after a major disruption - a breakup, loss, or a big change at home or work. He helps people untangle patterns that keep repeating, such as cycles of anger, avoidance, or people-pleasing. When blended household issues or stepfamily challenges are part of the problem, he addresses practical adjustments and relationship roles that create tension.
Sessions also cover practical day-to-day struggles like sleep, eating, work stress, and parenting strain. He works with issues related to ADHD, grief, intimacy, body image, and commitment concerns. The focus is on what someone can try between sessions and how to test small changes.
People meet him to work through specific problems and to build better habits for handling future stress. To begin, the reader selects the online therapy options button, completes a short matching questionnaire, and schedules an initial session.
Therapeutic approaches and working online
Client-Centered Therapy focuses on the client's perspective and priorities. The therapist listens closely and helps people find their own solutions, which can help with relationship and self-esteem concerns.Cognitive Behavioral Therapy (CBT) looks at how thoughts, feelings, and actions link together. It teaches practical techniques to change unhelpful thinking and behaviors, useful for anxiety, depression, sleep, and coping with stress.
Dialectical Behavior Therapy (DBT) offers skills for managing strong emotions and improving interpersonal effectiveness. It is often used when people struggle with intense anger, impulsivity, or recurring conflict.
Finding the right approach is part of the work together. The therapist will review which methods fit a person's needs, goals, and preferences and will adjust the plan as progress or challenges appear. This collaborative process helps keep sessions focused and practical.
The profile does not list specific session formats, so confirm current options before booking. Many people find online sessions easier to fit into busy days, allow quicker check-ins, or make it simpler to continue therapy after a move. Discussing timing and session length during the initial matching step helps set realistic expectations for how therapy will fit into everyday life.
