My name is Elizabeth Penniston, and I am a Licensed Clinical Social Worker (LCSW) with a degree from Saint Louis University. Throughout my academic journey, I dedicated myself to gaining both theoretical knowledge and practical experience, which led me to complete my practicum and supervision at a respected Domestic Violence organization. This experience has allowed me to work closely with individuals who have faced challenging and complex situations, further enhancing my skills in trauma-informed care, advocacy, and therapeutic support.
I am deeply committed to providing compassionate and effective mental health care, utilizing evidence-based practices, and fostering a safe environment for my clients. My work has instilled in me a profound understanding of the unique needs of those affected by domestic violence and the importance of empowering individuals as they navigate their healing journey.
Hi there! Just a little bit about me; I am a wife, a mom of twins, a lover of books, an Eight on the Enneagram & I love the work that I am blessed to do every day. I have my MS in Counseling as well as my certificate in Life Coaching. I am licensed clinically in KS & MO, and I am a Supervisor in both states. I specialize in treating eating disorders. I also enjoy working with anxiety & mood disorders, perfectionism and other co-occurring disorders.
I have over 20 years of experience in healthcare. My career began as a pharmacy technician, then as an emergency room nurse, and later supervising behavioral health units at Mercy St. Louis before becoming a Psychiatric Mental Health Nurse Practitioner.This background allows me to understand mental health from both medical and psychiatric perspectives.
