Mental Health Team

Josh Holloway
CEO, Owner, LCPC

I am a man of faith & family. I am married to an amazing woman, and have 4 fabulous kids! We love to spend time with friends and their families and enjoy gaming together as nerdy as that may sound.

I genuinely love people and helping. I very much consider myself a guide or a partner with my patients. Many of us have answers lurking under the surface, those answers that seem so far out of reach. Therefore, we lay awake at night, often get stuck in situations we see no way out. It is my goal to help you narrow down your thoughts and focus them on goals, which in turn help you find peace and learn again how to make the world small.

I do so through collaboration with other professionals and people (Natural Supports) you already have built into your life. As a guide, the patient and I collaborate and walk through the therapeutic process together. Operating from: Bibliotherapy, ACT, CBT, and psychodynamic perspectives we team up and work toward helping you find freedom! Bringing back “hope” that in today’s world is often a fleeting or unimaginable pastime.

Anna Rosteck
Clinical Supervisor, LCSW

Hello! My name is Anna Rosteck. I’m a Licensed Clinical Social Worker, an Ordained Minister with the Assemblies of God, and a Missionary to Tanzania, Africa. I’ve been working in mental health for 15 years, and have a passion for showing God’s love to others. In my free time, I enjoy spending time with friends and family, exploring the outdoors, and traveling.

Roberta Powell
Clinical Supervisor

Greetings! My name is Roberta (Berta) Powell, and I was born and raised in Great Falls, Montana. My husband, Larry, and I have two grown sons and daughters-in-law and are the proud grandparents of 3 grandchildren, ages 5, 13, and 15. We enjoy camping, gardening, and feeding our friends and family!

As a 1999 graduate of U.G.F. (now the University of Providence), I became a Licensed Clinical Professional Counselor in 2001, and have served women, children, couples, and families in this community ever since. I especially enjoy working with depressed and anxious women, helping families through empowering moms. I am a believer that “change comes in relationship,” and focus heavily on the importance of a healthy attachment process in both brain development and healing.

I have known Josh Holloway since 2011, and have witnessed his strong commitment to helping individuals and families improve their functioning and relationships. Having been Josh’s clinical supervisor as he worked toward licensure, I was honored when he asked me to join Open Door as both a clinician and supervisor of clinical interns. I am looking forward to mentoring a new generation of competent and compassionate therapists, as we serve our community together!

My name is Katie Ndongala. I grew up in a rural Montana community where my family farmed and ranched. I love Montana families and have the heart to see them grow and thrive spiritually and emotionally.

My passion for spiritual and mental health coincided in college in 2008 when I took my first psychology class! I studied Counseling in Texas and got a Masters in Social Work in New York.

In New York, I worked in a youth homeless shelter. My husband and I have worked with youth for the last seven years and work together to bring health to individuals & families.

My passion is helping people become healthy and whole, one step at a time so that they can live life in healthy relationships.

I am married to an amazing man and have two wonderful kids! We spend a lot of time together relaxing and enjoying the everyday moments with family and friends.

Ruxandra Fee
Mental Health Intern, LAC

Hello, my name is Ruxandra Fee. I am married and have two adult sons. In my free time, I enjoy spending time with family and friends. I also enjoy hiking, gardening, traveling, and reading.

I am a Licensed Addiction Counselor (LAC). I have a Bachelor in Addiction Counseling and Psychology from the University of Providence. My long-term goal is to obtain a master’s degree in Clinical Mental Health Counseling necessary to succeed in any counseling-related occupation. I am currently working towards my Master of Science in Counseling.

My personal life experiences have helped me become empathetic and able to walk alongside individuals experiencing the consequences of substance abuse. My experiences have given me insight into mental illness and a strong desire to educate myself to become a counselor to help other victims of psychological trauma find freedom. I lived and worked in three different countries and am trilingual, speaking English, German, and Romanian. This life experience has helped me to become culturally sensitive to multicultural individuals and immigrants and aware of the struggles they experience. Speaking German also helped me to become accustomed to the culture of the Hutterite colonies.

Dominic Smith
Mental Health Intern

Hello, my name is Dominic Smyth. I’m originally from Liberia, Africa, and a citizen of the United States of America. After a little over eight years of service as a Parish Priest and Reserve Chaplain with the U.S. Army, I now serve on Active Duty as a Chaplain in the U.S. Air Force, with the 341st Missile Wing, Malmstrom AFB, MT. I am an ordained Pastor endorsed by the Evangelical Lutheran Church of America (ELCA). 

I completed undergraduate degrees in Philosophy (BA) from St. Paul’s College Major Seminary, Gbarnga, Liberia – Holy See, and Theology (B.Th.) from the Pontifical University of Thomas Aquinas, Rome, Italy – Holy See. I also completed a master’s degree in Divinity (MDiv.) at the Lutheran Theological Seminary at Philadelphia.

I cannot overstate enough the invaluable need to effectively learn and hone lifesaving skills, theories, and experiences in mental health that are indispensable in helping people rediscover and sustain their mental health. This is why I am pursuing my master’s in Clinical Mental Health Counseling at Liberty University.

I have a particular affinity for nature, especially the outdoors. I am married with kids and enjoy spending time with my family.

I am a born and raised Montana girl who enjoys exploring, reading, just having fun with friends, watching good movies, and much more. 

Part of the much more would be what I am privileged to do for my work. I love watching the transformation that can happen in people and part of that transformation happens in the body. I love getting to be a part of people finding healing or even just letting go of stresses. Thank you for the privilege of allowing me to work with you!
