I am a Licensed Professional Counselor in Missouri with over three years of experience helping individuals navigate and process traumatic events. I am passionate about supporting clients in growing and excelling amid life's challenges. I want everyone to grow and become a healthier, more balanced version of themselves.

I am curious and validating, providing a nurturing environment to talk openly and honestly about your struggles, strengths, weaknesses, needs, likes, and dislikes. I love helping people explore their unique and particular powers as well as how these powers impact their world and their relationships. As a passionate supporter of those who have been through unjust or otherwise traumatic experiences--including those experiencing discrimination based upon race or gender identity or sexual orientation--I am particularly interested in helping people gain skills for dealing with, and making sense of, the remnants of their pasts.

Having completed Bessel Van der Kolk's Trauma Research Foundation's Certificate in Traumatic Stress Studies in early 2025, I have a strong foundational understanding of the most cutting edge approaches to treating trauma. I am also comfortable using a combination of approaches, including Psychodynamic, Gestalt, and Acceptance and Commitment Therapy. I received an MSW from the University of Pennsylvania, a psychodynamically focused program, after which I completed Bryn Mawr's certificate program in psychodynamic psychotherapy. I have also completed 1 year of Gestalt Therapy training and the Acceptance and Commitment Therapy Immersion Program.

As an LCSW, my training emphasized the role of social environment--from the family to society at large--in how we construct our narratives, enabling me to help you make sense of what in your life is yours to own and what is a product of your environment.

I am a licensed professional counselor. I enjoy working with children as well as adults to help them achieve their goals.

I provide counseling therapy to individuals with an Open Bible, offering therapeutic insight from a Christian perspective. I am a trained, licensed therapist who understands God's role in healing and integrates Biblical principles into therapeutic conversations to guide you toward better mental health. GOD is Good! My goal is to help you see this through Scripture, which provides guidance and navigation through the toughest times in life. Your emotional pain is more than a physical or mental struggle – it’s a spiritual response to suffering. I’ll walk beside you as we examine what is true, worthy, honest, and right.

I believe that everyone deserves a safe space to feel heard and supported. I pride myself on being a proactive advocate for my clients, ensuring that every strategy we implement is tailored to their unique long-term goals.
