Trauma and PTSD therapists & psychiatrists in Saint Peters, MO

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.

You came here because something isn't working. Maybe it's the moods that swing without warning, the emotional intensity that keeps spilling into your relationships, anxiety that won't quit, or the weight of something you've been carrying for longer than you should have to. Maybe you've been leaning on substances to get through and know something needs to change.

I work with adolescents, adults, and seniors across Missouri through telehealth, and I specialize

in the kinds of struggles that don't fit neatly into one category: mood disorders, trauma, anxiety

borderline personality, substance use, and relationships under strain.

You've probably spent a lot of time pushing through — carrying the anxiety, the grief, the stress, or the weight of things you haven't quite said out loud yet. Maybe you've wondered if what you're feeling is "bad enough" to bring to therapy, or whether anyone would really understand your specific situation. It is. And they will. I'm Jenna Miller, a Licensed Clinical Social Worker supporting individuals across diverse backgrounds — offering a space where you can finally feel heard, not just managed.

My clients seek to understand and accept themselves and their life experiences. Together we will explore how your past is impacting your present, so you can ultimately move toward a better future.

I work with individuals, couples and families from an attachment and systems perspective, knowing we experience many wounds through relationships but through the right relationships we can also experience healing.

It is important in my work that I allow the client's cultural context inform my treatment.

I care about real connection, steady progress, and creating a space where you can show up as yourself. I’ve spent years helping people sort through heavy thoughts, navigate big life changes, and rebuild a sense of direction. I won't rush you or force you into a mold, I help you understand what matters to you and take the steps to move towards it. I'm happy to be the calm, steady guide who will walk alongside you.
