About Dennis

Dennis Siefker is a Licensed Professional Counselor (LPC) practicing in Colorado with 30 years of clinical experience. He works with people facing depression, addiction, trauma and abuse, relationship challenges, anxiety, stress, grief, and a wide range of other concerns.

He helps clients who struggle with intimacy-related issues, eating and sleeping problems, parenting strain, anger, low self-esteem, and career stress. There is also focus on ADHD, bipolar concerns, compassion fatigue, and coping with major life changes.

Dennis draws on Emotionally-Focused Therapy (EFT) alongside client-centered methods and cognitive behavioral tools. Sessions often involve naming hard emotions, looking at patterns in close relationships, and practicing different ways to respond. He also uses techniques from dialectical behavior therapy and existential approaches when helpful.

The work is practical and direct. Conversations aim to clarify what is causing pain now, try out new ways to communicate or cope, and build skills for daily life. Dennis pays attention to attachment and abandonment themes when those come up.

He sees how life events like illness, blended family changes, or disasters can complicate coping. He also addresses issues such as codependency, body image, and communication problems so people can get clearer about their next steps.

How Dennis integrates EFT, client-centered work and CBT online

Dennis uses Emotionally-Focused Therapy to help people spot and name the emotions that drive relationship patterns and painful interactions. EFT focuses on feelings and attachment needs to help people shift how they relate to themselves and others.

He also uses client-centered therapy, which centers the person's experience and pace. That approach emphasizes listening, reflection, and helping people feel heard while they explore what matters most. Cognitive Behavioral Therapy is used to identify unhelpful thinking and try practical experiments to change behavior and mood.

Finding the right mix of approaches is part of the process. The therapist will work together with the client to choose methods that fit the client's goals, preferences, and the issues at hand. That collaboration can mean combining emotion-focused work with skill-building from CBT when useful.

Session formats are not listed on the profile, so confirm the current online options before booking. Online therapy can make it easier to fit sessions into a busy week, allow shorter check-ins when needed, and reduce travel time. It can also let people choose audio-only meetings when camera time is difficult or use video when visual connection helps the work.
