As a dedicated psychologist specializing in neurofeedback, biofeedback, and quantitative EEG (QEEG) assessments, I am passionate about helping individuals understand and optimize their brain’s unique patterns for greater emotional, cognitive, and physical well-being. With a science-backed, holistic approach, I integrate cutting-edge brain-mapping technologies with personalized treatment plans to support clients dealing with anxiety, ADHD, trauma, sleep issues, and more. I believe in empowering people with insight into their own nervous systems, guiding them toward sustainable self-regulation and lasting change. Whether you're seeking peak performance or relief from long-standing symptoms, my goal is to provide compassionate, data-informed care that honors your individual experience.

Approach Description: My approach to therapy is integrative, client-centered, and rooted in neuroscience. I combine evidence-based techniques with advanced tools like neurofeedback, biofeedback, and QEEG brain mapping to tailor each treatment to the individual. By addressing the physiological foundations of emotional and cognitive challenges, I help clients achieve deeper awareness, resilience, and self-regulation. I view therapy as a collaborative process, where safety, trust, and curiosity guide meaningful change. Whether we’re working to calm the nervous system, improve focus, or process past experiences, my goal is always to support lasting growth from the inside out.
