My journey into this field was deeply influenced by my own personal experiences, which have shaped my desire to create a safe and supportive environment for others. I believe that vulnerability is a vital aspect of healing, and I strive to foster a space where clients feel comfortable sharing their struggles. By actively listening and validating their experiences, I aim to empower them to confront and overcome the obstacles in their lives.

I believe therapy should feel supportive, practical, and empowering. Clients often describe me as warm, direct, and easy to talk to. I work with adults who want to better understand their emotions, patterns, and relationships, and I focus on helping clients build skills they can actually use in daily life. You don’t have to have everything figured out to start—just a willingness to show up.

I am a board-certified Psychiatric Nurse Practitioner with a passion for integrative, whole-person care. By blending the principles of integrative psychiatry with a deep understanding of adult medicine, I am committed to treating the mind and body as a unified system. I believe that true wellness requires dedicated attention to both.

More importantly, I create a space where you can show up just as you are and feel truly seen, safe, and supported.
