About Dennis
Dennis Siefker is a Licensed Professional Counselor (LPC) based in Colorado with 30 years of clinical experience. He focuses on helping people who are facing depression, addiction, anxiety, trauma, relationship strain, and other difficult life challenges. Sessions aim to be steady and straightforward so people can make sense of their situation and take practical steps forward.
He uses a mixture of approaches, including existential perspectives that look at meaning and choice, client-centered work that follows the client's lead, and cognitive-behavioral techniques to change unhelpful patterns.
Background and approach
That combination lets him address both immediate symptoms and deeper questions about values and direction. Dennis keeps sessions focused on real-life problems such as sleep and eating issues, parenting stress, career shifts, and coping with grief or loss. He pays attention to how past hurts shape present relationships and communication.
People also bring concerns like ADHD, intimacy issues, and compassion fatigue. Therapy here is collaborative. The therapist listens, asks direct questions, and offers tools clients can try between sessions.
Progress is measured in clearer choices, improved coping, and better daily routines rather than quick fixes. Sessions are offered in English and take place remotely through video calls, phone, live chat, or text-based messaging. Dennis works with adults seeking steady support for life changes, emotional healing, or skill-building.

Online support
How Dennis blends approaches for online care
Existential therapy focuses on questions of meaning, choice, and responsibility. It helps people facing big life decisions, loss, or a sense of stuckness by naming values and exploring how choices shape daily life.Client-centered therapy places the person at the center of the work. The therapist listens closely, reflects what he hears, and follows the client's pace so people feel understood before making changes.
Cognitive Behavioral Therapy, or CBT, looks at the link between thoughts, feelings, and actions. It offers concrete techniques to reduce anxiety, improve sleep and eating habits, and shift unhelpful patterns that keep problems going.
Finding the right mix of approaches is part of the first sessions. The therapist and client work together to decide what feels most useful based on needs, goals, and personal preferences. That collaboration helps shape a plan that can change over time.
Online therapy options include video calls, phone sessions, live chat, and text-based messaging. Video is useful for deeper conversational work and visual cues, phone works well when bandwidth is limited, live chat can be a quick check-in, and text messaging supports shorter updates or ongoing coaching between sessions. These formats make scheduling easier and let people fit care into busy lives.
