We’re Diana and Jose, your type 2 diabetes expert coaches! Diana is a Registered Dietitian, Certified Diabetes Educator, and has a Master’s in Nutrition Science. Jose is an Exercise Physiologist with a degree in Exercise Science.

Diana is a nationally-recognized Registered Dietitian, Certified Diabetes Care & Education Specialist and holds her Master's in Nutrition Science & Policy from Tufts Friedman School of Nutrition.

Diana graduated with a Bachelor of Arts in Communications from Villanova University in 2011. After working at Major League Baseball for over three years, Diana decided to pivot her career and pursue her passion for nutrition. In 2015, Diana received her Master's in Nutrition Science & Policy from Tufts Friedman School of Nutrition and her Didactic Certification in Dietetics from Simmons College. She completed her clinically-focused supervised practice in several different fields within nutrition including diabetes, cardiology, and oncology during her Dietetic Internship at UC San Diego Health. 

After passing the Registered Dietitian national exam, Diana decided to focus her career on type 2 diabetes. As a Registered Dietitian, Diana gained experience in various settings, including at Boston Medical Center, Labcorp, and InsideTracker. She worked alongside endocrinologists, dietitians, and other diabetes professionals, eventually fulfilling the requirements to become a Certified Diabetes Care & Education Specialist (CDCES).

In 2019, Diana met Jose and together they started Reversing T2D, a digital health platform that helps individuals reverse, manage, and prevent pre- and type 2 diabetes. Reversing T2D uses an integrative approach to tackle diabetes focusing on plant-based nutrition, exercise, and mindset.

As an advocate for health and the environment, Diana follows a primarily plant-based diet. She is a lover of nature and the outdoors, and you'll often find her hiking in Boulder, CO, where she resides. Diana enjoys teaching people about the benefits of plant-based diets and how to use this approach to tackle chronic illness especially type 2 diabetes. 

Jose is a plant-based certified health coach and exercise physiologist. He holds his Bachelor's degree in Exercise Science from University of Maryland.

Initially wanting to become a physician, Jose took pre-med courses at the University of Maryland and gained experience working with physicians who used plant-based nutrition to heal chronic illnesses, including diabetes. ⁠He saw patients reverse metabolic conditions just by following a plant-based diet; and was left utterly speechless after seeing an A1c of 16% come down to 9% in less than 2 months.

However, he changed his path after several physicians warned him about the mundane and repetitive nature of a physician’s job. He switched his major to Exercise Science and graduated as an exercise physiologist. However, his interest in plant-based nutrition persisted. After college, he worked with scientists who used plant-based nutrition to heal diabetes and became a certified plant-based health coach. 

In 2019, Diana and Jose met through Instagram and quickly realized how much their mission and goals aligned—wanting to help people with type 2 diabetes using plant-based nutrition and other lifestyle modifications. Together, they formed Reversing T2D.
