Introduction

As the Clinical Director of Fuse, my work is grounded in a commitment to thoughtful, evidence-based psychiatric care that remains open to new perspectives and emerging approaches. I believe that meaningful healing often occurs at the intersection of science, curiosity, and a willingness to explore beyond traditional frameworks. My approach integrates rigorous clinical standards with a broader, more holistic understanding of mental health. I aim to consider the full context of each individual, recognizing the interplay between biological, psychological, and experiential factors. Safety and efficacy remain central to every aspect of care, with careful attention to both established treatments and evolving research. I have a particular interest in ketamine-assisted therapy and the growing evidence supporting its use in conditions such as depression and trauma-related disorders. I view ketamine not as a standalone solution, but as a powerful tool that, when used responsibly, can facilitate meaningful therapeutic change within a structured process that includes preparation and integration. I am also deeply interested in the expanding field of psychedelic research and its potential to transform mental health care. This interest is guided by a commitment to ethical practice, patient safety, and long-term outcomes, with an appreciation for both the promise and the responsibility that come with these emerging treatments. At Fuse, my goal is to help create a space where innovation is balanced with integrity, and where individuals feel supported in pursuing lasting, meaningful change.
