About Dennis
Dennis Siefker is a Licensed Professional Counselor with 30 years of experience practicing in Colorado. He focuses on helping people manage depression, anxiety, addiction, ADHD, trauma, and relationship concerns. Dennis aims to create a calm, straightforward space where people can talk about what’s hard and figure out practical next steps.
Clients typically find sessions grounded and down-to-earth. Dennis listens first and then helps people try tools that fit their life.
Background and approach
He emphasizes better communication, clearer priorities, and small behavior changes that add up over time. His background includes long experience working with complex emotional issues such as grief, bipolar mood challenges, and co-occurring conditions. He also addresses concerns like anger, self-esteem, body image, and the stress of major life changes.
This depth lets him match the work to each person’s situation. Dennis uses a mix of approaches to suit the individual. He draws on client-centered listening, cognitive behavioral techniques for changing thinking and behavior, and skills-based work from dialectical behavior therapy.
He adapts sessions to what a person needs in the moment. People who are ready to try practical strategies and honest reflection tend to do well in his practice. Sessions can include goal-setting, skill practice, and talking through past hurts to reduce their hold on daily life.
He helps people take steady, manageable steps toward healthier routines and relationships.
Approach and online session options
Client-centered work focuses on listening and understanding a person’s experience. It helps people feel heard and then guides them to set their own goals and pace the work, which can be useful for relationship and self-esteem issues.Cognitive Behavioral Therapy, or CBT, involves identifying unhelpful thoughts and testing new behaviors. It is practical and useful for anxiety, depression, and many everyday habits that get in the way of functioning.
Dialectical Behavior Therapy, DBT, adds skills for managing intense emotions and improving interpersonal effectiveness. It offers concrete techniques for stress tolerance, emotion regulation, and clearer communication.
Finding the right approach is part of the work. The therapist will collaborate with each person to choose which methods to use based on goals, current struggles, and personal preferences. Sessions may blend elements from different approaches as needed.
Online therapy can make regular care easier to fit into life. Video calls allow face-to-face conversation; phone sessions can be shorter check-ins or fit high-motion days; live chat and text messaging let people share between sessions and track progress. These options add flexibility so therapy can continue despite distance, busy schedules, or variable daily demands.
