Background

I'm Kat, a California-grown, Hawaii-based Registered Dietitian Nutritionist who believes food should be both nourishing and joyful. After falling in love with nutrition science at Cal Poly San Luis Obispo and completing my internship at Pepperdine University, I became a Board-Certified Specialist in Renal Nutrition (CSR) because I saw how transformative the right nutrition approach could be for kidney health. As someone who's navigated celiac disease since age 15, I also bring personal understanding to helping clients with gluten-free needs.

What Makes Working With Me Different:

• Health at Every Size® practitioner - we focus on behaviors, not weight

• Sustainable change specialist - no rigid meal plans or diet rules

• Medical nutrition therapy expert (not weight loss)

• Plant-based nutrition guide (as a longtime vegan)

• Celiac and gluten-free expert (from personal + professional experience)

• Nutrition myth-buster - for confident food choices

Together, We Can Focus On:

✓ Protecting kidney function with personalized nutrition

✓ Managing blood pressure through enjoyable foods

✓ Creating satisfying plant-based meals

✓ Navigating celiac/gluten-free needs with compassion

✓ Developing a peaceful relationship with food

✓ Getting science-backed facts, not fads

My Personal Nutrition Journey:

When I was diagnosed with celiac at 15, I learned firsthand how overwhelming dietary changes can be - and how powerful the right support can be. This experience fuels my passion for helping others navigate health conditions without feeling restricted or overwhelmed.

More About Me:

When I'm not helping clients, you'll find me hiking Hawaii's beautiful trails with my husband, playing with my two adorable cats or reading (I devoured 230+ books last year!). I bring this same curiosity and dedication to your nutrition care.

Why Clients Love Working With Me:

• Realistic strategies that any lifestyle

• No judgment - all foods and bodies are welcome

• Science-based advice you can trust

• Personal understanding of dietary challenges

• Changes designed to last (no quick fixes)

Let's Create Your Nourishing Path:

Whether you're managing kidney disease, celiac, plant-based eating, or just want to feel better without dieting, I'm here to help. Let's build an approach that works for YOUR life - full of flavor, freedom and confidence.

Bonus: As a celiac, I promise to help you find gluten-free options that actually taste good!
