I am a registered dietitian and clinical nutritionist who spent years doing what every dietitian does, calculating BMI on a notepad, flipping through reference tables, building meal plans in Excel, and spending more time on paperwork than on patients.

That frustration became a mission.

TNS, The Nutrition Side, was built from the ground up by a dietitian, for dietitians. Not by a tech company that consulted a dietitian. Not by developers who read a textbook. By someone who has sat across from a patient, run the numbers by hand, and thought: there has to be a better way.
