Dr. Megan Mansfield is a Psychological Assistant (PSB94024218) working directly under the supervision of  Dr. Kate Truitt. Prior to her graduate studies, Dr. Mansfield served as a Crisis Interventionist and Advocate at Los Angeles’ longest-standing rape crisis center. Since then, she has continued to gain clinical practice and research experience to develop a specialization in the treatment of trauma, especially trauma caused by violence. Dr. Mansfield understands that troublesome or traumatic experiences often disrupt several aspects of one's life, such as relationships, work performance, spiritual connection, and physical well-being. This allows her to use a deeply empathic and holistic approach to foster genuine self-compassion and empowerment. Her knowledge of the impact trauma has on the brain enables her to provide treatment beyond traditional talk therapy, which leads to permanent neurological healing. 

My clinical practice and scientific studies have led me to specialize in the treatment of eating disorders, traumatic stress, and PTSD. My research focuses on brain health during the recovery process and treatment outcomes. I actively honor the belief that each individual is unique and dynamic and seek to connect with each client in a way that is safe and comfortable for where they are presently in their healing process. I strive to create an empowering environment for my clients, guiding them through their transformational journey as they seek and obtain their fulfilled life.

I was the first Certified Practitioner and am the first Certified Trainer of the Havening Techniques™in Los Angeles, California. Havening Techniques™ is a powerful treatment for traumatically encoded life experiences. Havening is an incredibly fast, efficient, and effective tool that heals the brain. As a result, the symptoms of trauma diminish and, frequently, permanently disappear. I am honored to release my clients from traumatic experiences that have resulted in the development of PTSD, depression. phobias, anxiety, anger difficulties, eating disorders, and many more ailments that have impacted them for years, sometimes decades. My clients report feeling empowered and stronger at the end of treatment as their brains heal and finally process the traumatic experiences that have kept them psychologically paralyzed.  Learn more in the book chapter Fifteen Minutes to Freedom in the book by the same title ​Fifteen Minutes to Freedom by Harry Pickens.

​Dr. Carter understands that while symptom relief may be success enough for many patients, going beyond symptom relief and focusing on healing the causes of the disturbance will lead to long lasting change. Dr. Carter seeks to not only support insight development into the patterns that get in way of living one's excellence but to also teach transformative skills to empower his patients to create long term health for themselves. Combining emotional regulation techniques informed through neuroscience with traditional talk therapy methods, Dr. Carter actively participates in the healing process of his patients. His patients experience great success by working collaboratively to build upon the strengths inherently present while focusing on creating opportunities to  unlock the ability to Live their Excellence.

Dr. Mansfield views the therapeutic process as a sacred collaborative experience that involves the mind, body, and spirit.

Dr. Mansfield frequently incorporates the Internal Family Systems model of psychotherapy founded by Dr. Richard Schwartz, to provide a clear, strengths-based, and empowering method of healing. With a sincere appreciation for the uniqueness of each individual, she works with each patient to discover the pace of psychotherapy that feels most meaningful and effective to them.

Shannon is passionate about helping people heal from the ‘inside out’ and within their relationships. In couples’ work her focus is facilitating each partner’s capacity to attune to and support the other’s personal growth. Shannon fosters the revealing of one’s self through an expression of feelings and thoughts, without blame or accusing, teaching them to respond with empathy while holding onto themselves. Shannon’s goal is to create a safe haven for individuals and couples to deepen their capacity for presence, healing, fulfillment and connection and achieve lives not only free from symptoms but filled with a new sense of vitality and hope.  

“I truly admire those willing to embark on the courageous journey toward transformation and am honored to stand beside them in their quest for happier, healthier, more productive and successful lives."   ~ Shannon Byrnes
