About the Therapists

Dawn Dungan MS, LCPC-S, CCTP


I began my career as a lay counselor in the Pastoral Care department of a local church here in Billings, MT.  I then decided to return to school to further my education so I could better understand how the psychological, physical, and spiritual (mind-body-spirit) components of a person interact to complete a picture of wellness.  I serve adults and adolescents age 15 years and over.  I offer individual, family, and couples counseling. My therapeutic orientations include primarily attachment-based, person-centered along with cognitive-behavioral, strengths-based, solution-focused therapies along with faith-based therapy when requested. I practice trauma-informed care.  I specialize in concerns related to sexual, emotional, and domestic abuse and trauma, PTSD, as well as depression, anxiety, grief and loss, boundaries, faith-based concerns, building coping skills, communication tools, relationship concerns, chronic illness, and end-of-life issues.  I am also trained in EMDR (Eye-movement desensitization and reprocessing) therapy. I have received training for and am a Clinical Supervisor.

Patti Barkell MS, PCLC


I started my journey in the counseling field as a pastor at a local church here in Billings, MT from March, 2007 through August, 2017.  I provided clinical, pastoral counseling (under supervision) for students (age 14 and up), individuals, couples, and families experiencing difficulties in their lives caused by emotional, physical and/or sexual abuse, grief and loss, identity issues, anxiety, depression, faith-based concerns, and relationship betrayals.

My decision to go to school was to further my education so that I could also be formally and scholastically trained to provide care in addition to faith-based counseling.  During my tenure, I noticed how difficult it is for people to live a balanced life, especially when we have unresolved trauma or other experiences that spill into our current situations, which led to my passion for helping those who struggle with complex trauma and PTSD.

My therapeutic orientations include person-centered with strengths-based, attachment-based, cognitive-behavioral, solutions-focused therapies, and faith-based therapy upon request.  I am also trained in EMDR (Eye Movement Desensitization and Reprocessing) therapy.  My goal is to offer assistance in understanding the connection between the psychological, physical, and spiritual (mind-body-spirit) components of an individual and how they interact with each other to provide a holistic approach to wellness by helping people learn tools, skills, and boundaries to address their needs.

Marlayne Worthington


I have always been a “people watcher” and have a keen interest in learning about what motivates behavior. As I continue my education and work to develop my skills as a counselor, I am able to draw on my experience of being married for the last 26 years, and the mother of 8 children.  I have also had the opportunity to serve as a youth leader of teens for 8 years. Those roles have given me the opportunity to learn about human development, behavior, and relationships. It has also given me experience in many of the trials that can stand as obstacles that prevent us from getting where we want to go and achieving the life we want. These struggles can come in the form of life events, transitions, or mental illness. Several years ago, upon completing my Bachelor’s degree, I felt strongly that I needed to continue on and receive my Master’s Degree in Counseling. Although that was not part of my original plan and had never been a career I had considered before, it felt right and it was something I knew I needed to do. My faith plays an integral part of my life, and to those who are seeking faith-based counseling, I feel that I can provide that as well. I look forward to working with my clients in finding meaning and purpose in their lives, to helping them achieve their full potential, and finding the joy and peace they desire in their lives. My therapeutic styles include solution-focused therapy, reality therapy, cognitive behavioral therapy and strength-based therapy. I treat individuals, couples, and families.
