Kimberly Brammer, M.A.

Clinical Director

Kim is a graduate of George Washington University and practices as a licensed professional counselor and board-certified (Art Therapy Credentialing Board) art therapist. She specializes in stress & anger management, emotional regulation, and art-based trauma interventions.

She began working at Tenley in 2016 and recently started a private practice. Kim has created and implemented therapy programs for adults and children in inpatient and outpatient facilities throughout the DMV area. In these facilities, she realized her passion of working with individuals who struggle with addiction, but came to realize that she wanted to assist clients in maintaining sobriety rather than detoxing.

She loves watching her clients change as they get further away from their active addictions. She believes that everyone can reach their fullest potential when their creativity is explored and put into practice, allowing them to benefit from greater degrees of profound self-knowledge and healing.

Outside of her professional life, Kim likes to hike and rock climb with her family.

Steve is a person who knows what it is to be in the throes of addiction, having been in recovery himself since 2003. Overcoming all the losses that people with addiction inevitably incur, he committed himself to doing everything he possibly could to help others avoid the ravages of alcoholism and addiction.

A native Washingtonian, Steve graduated from the highly respected counseling program at Loyola University of Maryland with a master’s degree in Clinical Mental Health Counseling. He has professionally helped people in recovery since 2011.  His training and education, coupled with his personal experiences, have helped him to quickly distinguish himself as one of the area’s most reputable substance abuse counselors.

     When asked about his approach, Steve is quick to point out that, above all, people in early recovery need compassion and empathy.  “We must find a way to make room in our hearts for those that suffer while understanding the that we deal with a disease that it cunning, baffling, and powerful.  It is therefore vital to understand when to encourage the client and when to challenge or confront the client.  Medical science provides much useful information for us. Bringing the hope of recovery to the individual person is where the art of effective substance abuse counseling lies!”  With great conviction he is fond of saying,” I love what I do!”  No one knows this better than the people with whom he works.

Steve also brings in experience as a successful Father, Husband and Businessman.


Mark Servatius, B.S

Mark started his experience in the chemical dependency field after completion of long term residential treatment at a therapeutic community called Operation PAR in Clearwater Florida in 1986. He had already completed a Bachelor of Science degree at University of West Florida in Management. The management discipline was a group experiential program focusing on behavior of an individual within a group setting and proved beneficial to both his future recovery and clinical endeavors.

Mark continued with Operation PAR in a variety of modalities including detoxification, residential treatment, individual and group education (especially for DUI offenders) and at the end of his time at PAR as a Senior Counselor (C-III) at PAR's Tier IV outpatient program at Clearwater Community Correctional Facility. It was a joint venture by PAR, the State of Florida and the US government. Mr. Servatius was not only responsible for doing the majority of the clinical work but also for day to day operations to satisfy The Joint Commission's (then JCAH) standards. He continues what has been a succession of volunteer and part time contributions to recovery which includes hundreds of hours of continuing education as well as over seventy-five hundred hours of group facilitation as both a primary and secondary counselor, facilitator and educator.

In June of 2004 Mr. Servatius was recognized as an "Unsung Hero" by Caron Foundation at their inaugural Washington Metropolitan Community Service Awards Breakfast. He was cited for his diligent work in the Washington area delivering the message to those "affected by their addiction so that they can overcome their disease and live a sober life...."
