Meet Theresa

I'm a board-certified Registered Dietitian Nutritionist with 18 years of experience in clinical nutrition. My areas of focus include heart health, cholesterol and blood pressure management, and sustainable weight loss — the kind that sticks.

I built these tools because I believe good nutrition information should be accessible to everyone — whether you're an ICU dietitian running complex calculations or someone just trying to make better choices at dinner tonight.
