Background

My passion as a registered dietitian lies in increasing food literacy—empowering individuals and families with the knowledge to make confident, nourishing food choices that are supportive of their health and lifestyle. I believe that understanding what we eat is the first step toward building a healthier, more balanced life. This belief was a cornerstone of my public health internship, where I focused on weight loss and weight management. Through this experience, I developed a deep understanding of the practical and emotional challenges people face on their health journey, and I learned how to create sustainable strategies that go beyond short-term fixes.

In my practice, I have had the privilege of working with families to navigate some of their most significant nutrition challenges. I have extensive experience in helping parents manage diabetes in their children, providing them with the tools and support needed to balance blood sugar levels while still allowing their kids to enjoy a normal childhood. Additionally, I specialize in addressing picky eating challenges, offering practical, stress-free solutions that turn mealtime battles into opportunities for exploration and growth. My goal is to create a positive and supportive environment where parents and children can learn to love food and feel confident in their dietary choices.
