Meet Mackenzie

Professionally…

I am a clinical psychologist (having completed my Ph.D. in 2002 from the University of Texas at Austin) and became a Somatic Experiencing Practitioner (SEP) in 2014. I have worked primarily with veterans with addictions and combined mental health problems since my internship at the Central Texas Veterans Health Care System from 2001-2002.

Dr. Mackenzie Steiner

I never saw myself in the long-run working in addictions or with veterans, but was surprised by how meaningful both were for me starting during my internship.  I came to realize that the reasons I found this rewarding made a great deal of sense, since I have a family history of addictive behaviors and also of military service.  While the latter was not entirely hidden, it was always kept in the periphery by my maternal grandfather, most likely as a result of trauma from his service during World War II.   After a brief stint in private practice I decided to take a job at the Central Texas VA and eventually accumulated a total of 20 years of federal service as the team lead and manager of the integrated substance and mental health treatment program; modernizing and adapting the program in keeping with scientific research and best clinical practices as well as supporting the growth and autonomy of my teammates to do the same.  I am deeply proud of our team and the work we did.   

These years of practice were fertile ground for learning how to treat people with the broadest possible range of mental health problems, including various anxiety disorders, mood disorders like depression and bipolar disorder, schizophrenia and other forms of psychosis, and challenging cases of complex PTSD and dissociative disorders (including dissociative identity disorder).   As a result of this, I sought out advanced training in mindfulness practices (like Mindfulness Based Cognitive Therapy and Mindfulness Based Stress Reduction, treatment for dissociative disorders and complex PTSD, family systems, Accelerated Experiential Dynamic Psychotherapy, and Somatic Experiencing). While I already came to this job with an appreciation of differences economically, I am profoundly thankful for the way my work at the VA brought me into the lives of so many people I otherwise never would have met and humbled my mind and heart to appreciate the incredible diversity of human experience (outside of the relatively privileged and secluded life of a white child growing up in a small rural community).  

Lastly, as I articulate more below, I have never felt “at home” in any one approach to treatment (as my mosaic implies) and have been deeply challenged and ultimately enriched by the process of bridging and connecting these various approaches to recovery and healing.

Personally…

a little history

I grew up in a conservative and traditional tight-knit family, the child of an introverted, artistic, diligent and nature-loving mother from a blue-collar family and a hard-working surgeon and hard-playing father from a white-collar family.  We lived mostly throughout California, eventually settling down on what we turned into a small ranch in the stark beauty of a small town (Felton) in the redwood-blanketed mountains outside of Santa Cruz.  I had the fortune of being immersed in the beauty of nature and raising and tending the land and our menagerie (horses, cats, dogs, sheep, goats, chickens, geese, rabbits, etc).  We were a very active family and I started early in sports like soccer, tennis, and skiing/snowboarding.  Thanks to a summer trip to Yosemite, I found one of my life passions in rock climbing.   Through college and my younger brother, I became increasingly aware and appreciative of liberal and progressive perspectives; particularly related to environmental and ecological perspectives emphasizing the complex and essential systemic relationships among all things and the ways in which ignorance and disrespect for them could wreak havoc.   It was in graduate school that this ecological perspective was expanded into the area of human behavior and relationships, which has become my guiding passion ever since both personally and professionally. 

In my heart…

I am introverted, introspective, and curious by nature, loving to stay active and get outdoors often. I am committed to values of integrity, wisdom, humility, harmony, and service.  I have known deep love and commitment to family through my 25+ year marriage and my two young adult children, but several years after coming out and attempting to preserve our marriage I have also learned that sometimes in our pursuit of personal truth some of these fundamental relationships must evolve as well. 

From early in life I never felt like I really fit into or identified with any one community, but rather connected with people across different types of communities and cliques. At the core, I think a significant factor in my not identifying with any exclusive group or community arose out of how, despite being assigned male at birth, I identified much more strongly with the feminine. I lived most of my life internally identifying as androgynous, what would now be called non-binary, until I came out as transgender in 2021. I fundamentally see myself as a bridge-builder and feel one of my greatest strengths has come as a result of having traversed many different frontiers over my life; both personally and professionally related to things like gender, spirituality, political identity, class, and race/ethnicity.  As a result I am able to respect and connect with people across a broad array of different backgrounds, recognize that what binds us is greater than our differences, and remain humble enough to recognize there is much about others and this world we live in that is a mystery we can choose to explore. 

Spiritually: While originally on the atheist side of agnostic, nature was my spiritual home and from a young age I was intuitively drawn to other traditions that centered nature in their spirituality. While I have always retained a spirituality centered around nature, over the years I have embraced traditions and practices from Buddhism as well as mystic Christian theology (the latter inspired by prior ministers Tim and Barbara Cook of the Church of Conscious Harmony), I deeply value finding the common spiritual values that cut across different traditions and faiths and believe that incorporating one’s spirituality in therapy greatly supports our life journey and our capacity to change.

May I step into the mystery with you?
