Co-Founder & President

TrueSelf Foods was the first producer of Certified FODMAP Friendly foods in the United States. A growing body of research has found certain foods, which are high in fermentable sugars known as FODMAPs, may trigger symptoms associated with gastrointestinal discomfort. A diet lower in FODMAPs may bring meaningful relief from these symptoms. I oversaw the operations of the company as President from initial ideation and company formation, through product development and brand creation, go to market strategy and sales to individual consumers and third-party retailers. I'm honored to have worked with my other co-founders to raise awareness of this diet and to help meet the needs of a significant portion of the population that suffers from these symptoms.
