What should a new client know about working with you?

My approach to care is compassionate, collaborative, and personalized. I believe that every individual deserves to be heard, understood, and treated with respect. I take the time to listen carefully to your concerns and work with you to develop a treatment plan that aligns with your goals, values, and lifestyle. I provide evidence-based, holistic care that considers the connection between your mental, emotional, and physical well-being. Whether you're seeking support for ADHD, anxiety, depression, insomnia, or substance use, I strive to create a safe, nonjudgmental environment where you feel comfortable asking questions, expressing concerns, and actively participating in your care. My goal is to build a trusting therapeutic relationship and empower you with the tools and support needed to achieve lasting wellness.

What is your typical process for working with clients?

During your first session, we'll take time to get to know one another. I'll ask about your medical and mental health history, current symptoms, life experiences, and what brings you to treatment. Most importantly, I want to understand your goals and what you hope to achieve. Our first visit is a safe, supportive, and judgment-free conversation where you can share your concerns at your own pace. Together, we'll discuss your symptoms, explore treatment options, and develop a personalized plan that fits your needs. My goal is to ensure you leave the session feeling heard, understood, and confident about the next steps in your care.
