Shannon Murphy Cerise

Licensed Clinical Social Worker (LCSW) in Texas and Louisiana

Shannon is a Certified Theraplay® Therapist, Trainer, and Supervisor-in-Training.  In addition, she is a Trust-Based Relational Intervention (TBRI) practitioner and holds a post-graduate adoption-competent practice certificate from Louisiana State University.  She completed the Adult Attachment Interview Training program in 2019.  

Since 2016 Shannon has worked for a nonprofit in Dallas with a long history of serving vulnerable children and families.   Her practice currently centers on helping biological, adoptive, and foster families that are experiencing stress, struggle, and disconnection.  From 2006 to 2014 Shannon worked for a nonprofit in Baton Rouge, first as a therapist for people impacted by Hurricane Katrina and later as a specialized adoption therapist.  From 1993 to 1998 she was the director of a residential and educational program for at-risk youth. 

Regarding supervision, Shannon considers herself a life-long learner and approached her own Theraplay training as an opportunity to challenge herself professionally and personally.  Specifically, she sought to build clinical skills in working with children and caregivers, lean hard into authenticity and transparency within the supervision process, and stretch and grow her capacity to live in the present moment.  Training and supervising clinicians with The Theraplay Institute are the newest iteration of her desire to learn and grow.

In a volunteer capacity, Shannon serves on the Advisory Board for the Karyn Purvis Institute of Child Development at Texas Christian University, the Interracial Healing Task Force in the Diocese of Dallas and is a member and past chair of the Board of Bishop Dunne Catholic School in Dallas.  She is a sendee of the Living School, a program of the Center for Action and Contemplation in Albuquerque, NM, where she developed her contemplative practice.  Mother to three children, now young adults, she enjoys exercising, reading, puzzling, and making new friends, particularly in her role as the co-founder of Dallas’ Multicultural Women’s Book Group. 

If her background and interests resonate with you as a new Theraplay practitioner, Shannon would be pleased to connect with you.  She can be reached at [email protected].
