Co-Founder | Co-Chief Executive Office | Chief Operations Officer

As the visionary leader of Advanced Allergy Therapeutics (AAT), I have been driving the company’s digital evolution and strategic expansion since co-founding our technology platform in 2005. From the beginning, my mission has been to transform the way practitioners address the symptoms and conditions associated with allergies and sensitivities, scaling AAT into a global leader by advancing innovation, expanding our reach, and ensuring our technology remains at the forefront of the industry.

My leadership extends beyond operational oversight—I focus on big-picture strategy, scalability, and market expansion, ensuring AAT continues to empower healthcare practitioners with cutting-edge tools to help their patients. A cornerstone of this vision was my role in designing AAT’s graphical user interface, ensuring a seamless, intuitive experience that enhances both usability and patient outcomes.

AAT’s success is built on supporting our practitioners—not just through technology, but through education, marketing resources, and strategic business development. I am committed to equipping them with the tools they need to grow their practices, expand awareness of AAT in their communities, and improve patient outcomes through symptom relief.

Before AAT, I built a career in global brand strategy and market development, working with industry leaders such as Warner Bros., Macy’s, The Gap, and Neiman Marcus. I led international brand expansion, overseeing creative and strategic execution across diverse global markets, including Hong Kong, Singapore, Japan, and Australia. These experiences shaped my ability to navigate cultural nuances, consumer behavior, and brand positioning on a global scale—a skillset I now leverage in AAT’s continued expansion.

As AAT moves into its next phase of growth, my focus remains on scaling our impact, optimizing our business model, and expanding into new markets. The future of AAT is global, and I am dedicated to ensuring our technology reaches more practitioners and helps more patients worldwide.

Beyond AAT, I am passionate about personal development, leadership, and mentoring the next generation of industry innovators. Living near Lake Tahoe, I find inspiration in travel, exploring new cultures, and the adventure of hiking and mountain biking through the Sierra Nevadas.

Co-Founder | Co-Chief Executive Office | Chief Clinical Officer

As a Co-founder of AAT, I’ve had the privilege of playing an instrumental role in the company’s growth and evolution since 2001. As the Chief Clinical Officer, I oversee AAT’s training, treatment protocols, digital library, and clinical operations. Over the past two decades, I’ve personally trained more than 400 AAT practitioners worldwide, supporting them to successfully integrate AAT into their practices. I have also played a pivotal role in expanding AAT into international markets including Australia, Japan, Canada, and the United States, by training, launching, and managing multiple seven-figure AAT clinics globally.

From AAT’s early development to its current global reach, I’ve been at the forefront of our innovations. My contributions span software and protocol development, treatment and training implementation and the creation of our online training program. I am especially proud to have built and organized our comprehensive digital library, which includes over 65,000 substances and continues to grow. This library enables practitioners to perform highly accurate assessments and deliver personalized treatments, making it a cornerstone of AAT’s effectiveness and success.

I continue to lead clinical training for all AAT practitioners, ensuring the highest standards in the therapy’s application. Beyond training, I stay hands-on with the practitioners, providing clinical support, addressing inquiries, advising on cases, and refining best practices for the therapy.

Alongside my leadership role with AAT, I’ve had the honor of successfully treating thousands of patients with the AAT therapy over the past 25 years as a licensed acupuncturist, and I continue to maintain a private practice in Northern Virginia. Working directly with patients keeps me attuned to the challenges practitioners face and helps me stay current with health trends and the evolving needs of both patients and practitioners. This experience drives my commitment to continually improve and expand the AAT therapy. To further this goal, I regularly collaborate with a select group of experienced AAT practitioners—including medical doctors, chiropractors, acupuncturists, naturopaths, and nurses—to explore ways to enhance treatment options and outcomes across the AAT community.

Passionate about patient care, I find fulfillment in teaching and training practitioners to incorporate AAT into their practices, knowing it can help more people. As a lifelong learner, I am dedicated to continuous study in the field of health and wellness for both the mind and body, firmly believing that with the right tools, the body can heal itself. Outside of work, I enjoy spending time with my husband, traveling, and staying active outdoors.
