Dennis Siefker

Dennis Siefker is a Colorado-based therapist with 30 years of experience in the mental health field. He has worked across both inpatient care and outpatient services, serving a range of clients and clinical needs. His background includes work with family systems, individual and family counseling, domestic violence interventions, chemical and gambling addiction treatment, and care for severe mental health needs.

Currently, he provides services in a correctional setting and leads a specialized Juveniles Convicted as Adults Program that assists offenders in transferring from a correctional setting after serving at least 25 years of their sentence. He approaches counseling from a client-centered, solution-focused perspective, integrating cognitive-behavioral techniques with logotherapy to help those who choose to engage in therapy explore the drivers of their behavior and address purpose and meaning in their lives.

Logotherapy, which he uses alongside other methods, is a school of psychology and a philosophy that emphasizes the human motivation to live purposefully and meaningfully. It holds that people find meaning by responding authentically and humanely to life’s challenges. By examining belief systems through logotherapy, clients can gain clearer insight into how to make changes to their thoughts, feelings, and actions.

He is a licensed professional counselor in Colorado, and his long career spans work in institutional and community settings aimed at helping individuals and families move toward healthier, more purposeful lives.
