​​​
If you’re searching for a registered dietitian in Frisco or Prosper who understands blood sugar, weight gain, and real medical conditions, you’re in the right place.
​
​​Catrina works with adults who feel:​
• Frustrated with high blood sugar or rising A1C
• Confused about what to eat for diabetes
• Stuck with weight that won’t move
• Worried about high cholesterol or heart health
• Overwhelmed after a new diagnosis
• Tired of being told to “just lose weight”
Catrina brings a strong clinical foundation to her work, blending hospital-based experience with a practical, real-life approach to nutrition. She previously worked at Baylor Scott & White Health, where she supported patients managing complex medical conditions including diabetes, heart disease, kidney disorders, GI concerns, wound healing, and critical illness. That experience allows her to approach each client with both clinical precision and compassion.
​
She understands that lab numbers can feel intimidating and diagnoses can feel overwhelming. Instead of handing you a rigid plan, Catrina focuses on helping you understand what’s happening in your body and what realistic steps will move you forward. Her approach is structured but flexible — rooted in evidence, but tailored to your life.
​
At Marley Nutrition, her focus is prevention and long-term stability. Whether you’re working to improve A1C, support heart health, or build sustainable weight loss habits, she helps you create a plan that feels doable and grounded — not extreme.
​
Her goal is simple: to help you feel steady in your choices, confident in your labs, and supported every step of the way.
