Addiction therapists & psychiatrists in Wichita, KS

I believe therapy works best when you feel understood, respected, and never judged. My approach is collaborative and practical, helping you develop skills that you can use outside of our sessions rather than simply talking through problems week after week. I primarily use Acceptance and Commitment Therapy (ACT), an evidence-based approach that helps people respond differently to difficult thoughts and emotions while taking meaningful action toward the life they want to build.

Whether you're struggling with anxiety, depression, trauma, life transitions, relationship challenges, or overwhelming stress, my goal is to create a space where you can be honest about what you're experiencing and feel supported as we work toward lasting change. I strive to balance compassion with directness, offering both validation and practical strategies to help you move forward in a way that aligns with your values.

If you’re feeling weighed down by anxiety, depression, trauma, mood shifts, or ADHD symptoms and wondering whether medication could help, you’re not alone. I work with teens and adults navigating mood and anxiety disorders, PTSD, OCD, ADHD, and stress-related challenges.

Clients often tell me they appreciate my mix of medical expertise and genuine compassion. With a background in both psychiatry and intensive medical care, I understand how closely the mind and body are connected. My goal is to make care accessible and consistent, which is why I offer flexible scheduling and telehealth appointments.

In our first sessions, we’ll review your history, clarify your symptoms, and determine whether medication is appropriate. If it is, we’ll build a treatment plan that feels realistic, evidence-based, and aligned with your goals and overall health.

Outside of work, I find balance through yoga, comedy, time with my dog, and enjoying sunny days — reminders that healing comes from both steady progress and moments of joy.
