About Dennis
Dennis Siefker is a Licensed Professional Counselor (LPC) in Colorado with 30 years of clinical experience. He works with adults facing issues such as depression, addiction, anxiety, grief, anger, and relationship concerns. He also helps people dealing with career strain, sleep or eating problems, ADHD, and the emotional fallout from trauma.
Dennis uses straightforward, conversational sessions to help clients sort through stress and recurring patterns. He focuses on practical skills people can use between meetings. Sessions often include talk, problem-solving, and strategies to change unhelpful thoughts and behaviors.
He draws from Client-Centered methods to follow the client's lead when exploring difficult material. He also uses Cognitive Behavioral Therapy to identify thinking habits that feed anger or anxiety. Dialectical Behavior Therapy skills are applied for managing strong emotions and building tolerance for distress.
Dennis pays attention to how attachment, abandonment, and communication problems affect relationships. He works with people who face blended family concerns, caregiver burden, or codependency, and those coping with chronic health challenges like cancer. He does not claim to diagnose or guarantee outcomes, but aims to help people make clearer choices about their next steps.
People who prefer plain language and direct feedback may find his style a good fit. To begin, readers should confirm current session formats and scheduling details before booking.
How sessions work
How therapeutic approaches translate to online work
Client-Centered Therapy focuses on the person's own goals and experience. Online sessions using this approach let the therapist follow what matters most to the client and build on the client's priorities.Cognitive Behavioral Therapy (CBT) targets the thoughts and behaviors that keep problems active. In remote sessions CBT can include reviewing thought patterns, assigning short practice exercises, and tracking changes between meetings.
Dialectical Behavior Therapy (DBT) offers specific skills for handling intense emotions and reducing impulsive reactions. Online DBT-style work tends to focus on learning a few concrete skills for distress tolerance, emotion regulation, and clearer communication.
Finding the right approach is part of the process. Dennis will work collaboratively to choose which methods fit a client's needs, goals, and preferences rather than assuming one way will suit everyone.
Session formats are not listed here, so confirm current options before booking. Online work can make it easier to fit therapy into a busy life - sessions can be shorter check-ins, used during lunch breaks, or arranged so travel time is reduced. The focus is on practical adjustments that help people apply skills in real situations.
