Helping You Navigate The Renal Diet And Optimize Your Nutrition

Maria in kitchen

Welcome! I’m so glad you’re here. 

My mission is to provide easy to understand, evidence-based nutrition information to help people live a healthy life on dialysis. This is an area that I am passionate about! 

Transitioning to life on dialysis and learning the “renal diet” has its challenges to say the least. As a specialist in kidney nutrition I am here to provide the support you deserve to hopefully make the process a little easier. 


I am an experienced Registered Dietitian Nutritionist who has specialized in kidney disease for over 19 years. 

Our understanding of your nutrition needs on dialysis has evolved over the years -especially recently with a more plant-based focus. 

As a Certified Specialist in Renal Nutrition my goal is to reach more people and have a larger impact on the chronic kidney disease community. 

Stay connected for monthly blog posts with informative information! I am here to serve you and appreciate your support.
