The Team

Viken Matossian, MD
Child and Adult Psychiatrist

I was exceptionally lucky in my early exposure to brain science as well as psychotherapy. I trained under some of the pioneers of modern psychiatry; Sam Guze, Eli Robins, Barb Geller, to name a few.  I had a firm foundation in brain research and basic science working in the lab as an undergraduate with Gerry Fishbach, who was a pioneer in studying how nerves grow and make healthy chemical signaling connections.

This basic pharmacology work prepared me well for the flood of new medications that have come into common use in psychiatry.  Though my primary role in the clinic is to support psychotherapy with medications, I still view medications with a healthy dose of  caution. I was deeply influenced early on by family systems therapy, which shifts focus from individual disease to seeing behavior as a product of a system of family and community relationships.   In my fellowship program in child and adolescent psychiatry my training concentrated on family systems therapy, dyadic play therapy, interpersonal therapy, dynamic trauma therapy, and forensic interviewing for sexual abuse cases. I also continued work in the lab on the side, working on genetic studies for autism, bipolar disorder, and Tourette's syndrome; this led to yet another year extension of my training as I went on for a post-doctoral fellowship in genetics of personality development at Western Psychiatric Institute and Clinic in Pittsburgh.

With Advanced Behavioral Medicine, I have worked to create an evidence-based clinic relying on state-of-the-art methods in both psychotherapy and sensible, informed use of medications. We aim to improve not just the quality of life of our patients, but to improve the whole community, sharing collaboratively with local physicians, mental health providers, lawyers, law enforcement, and schools.

I have been working as a professional psychotherapist for over 25 years. I enjoy a diverse practice working with all ages, including young children and the elderly. When you come to me with a problem, I will try to understand the full context of your experiences, your relationships, your talents, and the challenges you confront every day to help you find the most effective ways to improve your life. In working with children, I meet regularly with their parents and consult whenever possible with others who care for them, such as extended family and teachers. In working with adolescents, I create a space where they can look beyond their immediate crisis and start to see who they will become. You will find some of the most effective, research-proven techniques, like cognitive behavioral therapy, family systems therapy, exposure and response prevention therapy, individual and parent-child play therapy, and a variety of dynamic therapies in my tool box, but I am mindful that the tools aren’t there for me; they are for your use.

All people have resources for self-healing and my goal is to help you mobilize these strengths. I keep up with advances in the field and train with outstanding teachers when game-changing new techniques come along so I can get you where you want to go as quickly and efficiently as possible. While I love a quick ‘cure’ as much as anyone, I’m dedicated to working hard for you for as long and as often as it takes to get you back on track in your life, while always looking for a new approach or opportunity to get you on your feet again. I am compassionate and tactful, but also direct and practical. We will have a clear path, specific goals, and regular reviews of where we are on that path and what we can do better. I have a very broad background in psychotherapy techniques, and I am always adding more training and skills. I am a Certified Advanced Alcohol and Drug Counselor, though my practice over 35 years has included much more than addictions counseling. I have excellent skills in the many dialects of cognitive behavioral therapy, marital therapy, interpersonal therapy, mindfulness therapy, biofeedback, and dynamic trauma therapy, to name just a few. I work with adults, couples, and families.

I feel privileged to work with people striving to overcome tough challenges in life. I consider myself a generalist, but I have especially extensive experience working with anxiety disorders, grief and loss issues, and depression. I understand that problems felt at a personal and private level are also exceptionally sensitive to the quality of relationships in the extended family, social network, and work environment. This expanded perspective when considering opportunities for change that are not obvious from considering only the viewpoint of a single individual. I provide parent consultations when I work with children and adolescents, and often meet with parents one-on-one. I am available to coordinate care with primary care physicians or participate in meeting with schools or other agencies. I have seen amazing benefits from counseling, but I also understand the courage it takes to seek out a better way of living life. I have the utmost respect for anyone who chooses to set out on the path of change.

She draws from an exceptionally firm grounding in narrative therapy, cognitive behavioral therapy, and dialectical behavioral therapy, but her outstanding talent is giving each person the sense from the first session that they will be heard and they will be well cared for.

As a Licensed Professional Counselor I am committed to helping each person reach their goals. Life can be difficult and counseling is a good option for those who are seeking to change, understand themselves better, and explore solutions to their problems. As human beings we have a life-long capacity to change and with motivation, knowledge and effort, a greater level of physical and emotional health can be achieved. I enjoy working with teenagers, individuals, couples and families who decide to seek counseling for a variety of reasons. I have seen many positive things happen in therapy. With the proper tools you have the power to be the healthy person you want to become. I deal with marriage and individual counseling in a humorous way so it isn’t intimidating to anyone.

I am a highly experienced therapist who comes from a holistic perspective – that is, all aspects of a person’s life are significant. It is my intention that you experience a sense of being understood and cared for. I especially enjoy helping you find inner resources to understand and resolve your own difficulties. It is a tremendous relief to experience the ability to manage your busy, distracted mind, to calm overwhelming emotions, or to escape the constant distraction of chronic pain for the first time, through a specific blend of mindfulness meditation and cognitive behavioral therapy. I would love to see you turn painful experiences into increased strength, or transform anxiousness into confidence. As you discover your capacity to successfully manage your life challenges, you will feel empowered to love well in the world. I am also a Methodist minister, and I am qualified to discuss questions pertaining to a wide range of theological perspectives and scriptures.

This is what I would like you to know about me, so that you can feel a connection, or have a sense that I might be someone who knows what they are doing. I have been in the mental health field seeing adults, individuals, families, and couples for over 20 years. I can tell you that I have a history of working in many modalities and use cognitive/behavioral pattern-changing, problem-solving techniques. I love my work, as difficult as it is sometimes to hear and experience someone’s pain, anger, and fear.

I have learned something from every person who has shared their story with me. My clients have been my teachers. It is my deepest hope that I have been their teacher in some meaningful way.
Seeing a therapist can be your opportunity to create a relationship with your feelings and learn to trust your own knowing. Learning about yourself through the advantages of self-discovery can be one of the most powerful and valuable journeys of your entire life.

Do you find yourself trapped? Doing things that you never wanted to do? Is your child in trouble, withdrawn, angry, disrespectful, using drugs? Are you depressed, considering divorce? These are some of the problems I’ve been able to successfully assist people in addressing and overcoming.

I have 20+ years of experience working with individuals, families, groups and couples. I’ve worked in inpatient hospitals, outpatient clinics and prison settings. I’ve worked with patient populations in substance abuse, depression, anxiety, sexual identity, post-traumatic stress disorder, anger management, sexual addiction, African-American and Hispanic ethnic identity issues, and Christian identity issues.

Everyone deserves to have a good day and a better tomorrow. Coming to therapy is intimidating. So I strive to listen, listen again, and then respond to your needs. I have always been fascinated by how people change and grow and how images and words, when linked to feelings and self-insight, create lasting change. I realize that taking on a personal change out of desire or necessity is often harder than it sounds. How multiple attempts, will-power, and rewards are probably not enough. I know that the events of life do not always go the way we plan, need or desire. Personal growth is exciting and scary.

My aim is to help guide others through difficult storms to places of security, adventure, and wholeness. I enjoy working with all ages, life-stages, and conditions. People arrive with their bag of “stuff:” hopes, disappointments, wounds, trauma, diagnoses, affections, connections. Whether you’re new to therapy or deeply traveled, I always begin where you are at and work with you to create a path to a better place of well-being.

I have experience treating depressions, anxiety, addictions, trauma, and attachment. I use many therapeutic frameworks, including narrative, psycho-dynamic, cognitive, dialectical, and Internal Family Systems, to help people find meaning and hope. Professional training includes a Master’s in Divinity from Princeton Seminary, and a Master’s in Social Work from the University of Michigan, where I focused on the treatments for complex trauma. I’m currently working on becoming certified in Hand-in-Hand Parenting, parenting by connection.

On a personal note, I am married to a psycho-therapist with whom I have two children. Before moving to south-eastern Michigan 20 years ago to pastor a mainline Protestant church, I worked as a machinist and an advertising account manager.
