About Tiffany

Hi, I'm Tiffany, RD, based in Fresno, California. I earned a BS in food science and nutrition and bring five years of experience as a Registered Dietitian across clinical hospital settings and Renal/Dialysis care. I love exploring new foods, visiting different places, and spending time with my children, and I’m a coffee lover who believes good nutrition can fit into everyday joy. I’m here to listen, learn your story, and help you build a sustainable path to better health, one small, doable step at a time.

Approach to care

My care is guided by current science, but always centered on you. I work with an evidence-based approach that translates the latest research into clear, practical steps you can try this week. I’m empathetic and warm, and I won’t judge your food choices or your pace. We’ll set actionable goals, track progress, and adjust as needed. I practice with a Health At Every Size lens, focusing on behaviors and well-being rather than a number on the scale. We’ll educate you so you feel confident in every choice. Holistic care means considering sleep, stress, and daily routines alongside nutrition, and I’m here to guide you every step.

Your first session with Tiffany

Our first appointment is a warm, collaborative conversation, not a test. We'll start by reviewing your medical history and current care, then establish short-term goals that feel doable. We'll take a deeper dive into your relationship with food and the everyday patterns that support or challenge you. You don't need to have everything figured out yet; I’ll listen and we’ll tailor our plan to your life. Together, we’ll identify one or two practical next steps to begin your sustainable, long-term journey.
