Addiction therapists & psychiatrists in O'Fallon, MO

I have been provided therapy services since 2021. I was trained in EMDR in 2024 and have been practicing since then. I have worked with individuals of all ages, but prefer to work with ages 14 and up.

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.

I work with adolescents, adults, and couples and specialize in supporting clients facing addiction, anxiety, and depression. My goal is to help people grow through practical tools, self-awareness, and renewed hope.

I bring years of experience using evidence-based therapies to support meaningful change. Whether you’re navigating a major life shift, struggling with motivation, or working through long-standing challenges, I’m here to meet you where you are and walk alongside you as you move forward.

Hi, my name is Dr. Charles Quinn. I am a retired military soldier, served 25 years, and have been in the field of counseling for over fifteen years. I have worked with clients with a wide range of concerns, including anxiety, depression, relationship concerns, grief and loss, past traumatic experiences, conflict resolution, self-injury, bullying, and other issues. The modalities that I incorporate into my sessions are Cognitive-Behavioral, Dialectical Behavior, Solution-Focused, and Trust-Based Relational Intervention, among others. It is important to meet the client where they are and tailor a specific program that addresses their unique concerns and needs. I practice from a perspective of compassion, acceptance, and trust building. It is my mission to ensure my clients feel safe, not judged, and accepted as we begin to work together. I am committed to creating an environment that fosters truth without judgment, safety without fear, and hope in an otherwise hopeless situation.

Let's begin this journey together.
