The support I provide flexes between nutrition therapy and coaching, focusing on understanding patterns, reducing food anxiety, and building sustainable habits.
I work with adults and adolescents who feel stuck, overwhelmed, or frustrated with food, eating habits, or body dissatisfaction. While my specialty is eating disorders and mental health, I work with clients across the full spectrum of disordered eating. Many are tired of rigid rules, quick fixes, loss of control, or fear around food and eating. They want guidance that fits their life, helps them build confidence, and supports lasting change without guilt or pressure. My focus is on progress and healing, not perfection.

My ideal client can be of any age or background. They may be seeking weight loss, better performance, improved labs, muscle gain, or a healthier relationship with food. What matters most is that they’re open to problem-solving—willing to examine habits with curiosity, apply evidence practically, and use accountability to measure progress. They understand that change requires consistency, reflection, and course correction; if they’re not fully ready, they’re willing to explore what’s in the way.
