Find a therapist in O'Fallon, MO — covered by insurance

I’m Dr. Pearson, and I draw on over 30 years of counseling experience helping individuals, couples, marriages, families, teens, children, and organizations work through life’s challenges. I support clients dealing with depression, anxiety, stress, anger, relationship issues, family conflict, addiction and alcohol concerns, military-related stress, and major life transitions. My background includes working with people across many stages of life, including active-duty military members, veterans, DoD staff, military families, couples preparing for marriage, families under stress, and individuals seeking healthier ways to live at home, at work, and in their relationships. I believe therapy should offer hope, practical support, and a clear path toward healthy change.

If you are moving through a major life transition, especially one you did not choose, you may notice that old ways of coping no longer work. Many people I see are adapting to a new chapter, trying to build skills for what is next while caring about how change will affect the people they love. Some arrive unsure about trying therapy again after a difficult experience. Together, we explore how your family of origin and earliest relationships echo in what you face today.

Your story has made you who you are. I offer a judgement free space for you to share that story.

Hello!

I proudly bring lived experience to the table, so I know a different life than comes in textbooks. It increases my odds of understanding you better and of being able to develop unique strategies for you in a shorter amount of time. I've wanted to work in mental health since I was a child, and bring that enthusiasm to my work. Hope to see you soon.

If you're dealing with anxiety that won't let up, a life change that's left you off-balance, or relationship tension that keeps getting in the way — I can help. After 10 years as a school social worker in St. Louis, I know what it looks like when people are overwhelmed, and what it actually takes to move through it. Today I work with adults navigating similar territory: the pressure that builds quietly, the transitions that feel harder than expected, the moments in relationships that leave you stuck. My focus is on making therapy practical, grounded, and worth your time.

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.
