About Dennis
Dennis Siefker is a licensed professional counselor (LPC) in Colorado with 30 years of clinical experience. He focuses on helping people who face depression, addiction, anxiety, trauma, and parenting concerns. His style is steady and practical, aimed at clear steps rather than jargon.
He keeps sessions grounded in what a person is living now. That might mean sorting through stressors, building better communication skills, or working on sleep and eating patterns.
Background and approach
He pays attention to emotional safety and helps clients name what they are feeling. Dennis combines several approaches to match each person’s needs. He uses client-centered methods to follow a client's priorities, cognitive behavioral techniques to change unhelpful thinking and behavior, and elements of dialectical behavior therapy to teach emotion regulation skills.
These tools get applied in simple, real-world ways during sessions. He has particular familiarity with issues such as relationship problems, anger, self-esteem, ADHD, grief, and coping with life changes. He also addresses concerns like abandonment, attachment issues, blended family questions, and compassion fatigue.
The work often focuses on practical steps and habits that can be built between sessions. People who prefer direct guidance alongside empathetic listening tend to do well with his approach. Sessions are collaborative: goals are set together and progress is reviewed.
Dennis aims to help clients find clearer choices and more reliable coping skills for everyday life.

How different approaches are used in online therapy
Client-centered therapy puts the client's priorities first and creates space to talk through what matters. It helps when someone wants to be heard and guided at their own pace rather than following a strict plan.Cognitive Behavioral Therapy, or CBT, focuses on spotting unhelpful thoughts and routines and replacing them with more workable actions. CBT is useful for anxiety, depression, sleep or eating problems, and coping with stress by teaching concrete skills.
Dialectical Behavior Therapy, or DBT, emphasizes emotion regulation, distress tolerance, and practical coping strategies. It can be helpful for strong mood swings, anger, and relationship instability by giving hands-on tools to manage intense feelings.
Finding the right approach is part of the work. The therapist will collaborate with each person to decide which methods fit their goals and situation. That plan can change over time based on what is working and what isn’t.
Online sessions are offered as video calls, phone sessions, live chat, or text-based messaging to make therapy more flexible. Video allows a fuller conversation, phone calls can be easier if bandwidth is limited, live chat works for shorter check-ins, and messaging supports ongoing reflection between appointments. These options help people fit counseling into busy schedules and different daily routines.
