My role is to provide structured, individualized nutrition support that reinforces your recommendations while helping patients build sustainable habits outside the exam room. 

Nutrition is often the missing piece in reaching long-term goals, especially for patients managing metabolic conditions, cardiovascular risks, GLP-1 medications, or chronic disease.

I partner with physicians & healthcare providers to deliver thoughtful, evidence-based nutrition care that supports your treatment plan and offers patients deeper guidance for long-lasting results.

Who I partner with

Areas of Focus

A no-pressure introduction for your patient to ask questions, understand how I work, and decide whether we are the right fit. Always complimentary, no commitment required.

Referred patients do not need to commit to a monthly membership to get started. They can be seen on an a la carte basis, at a discounted rate and transition to a membership at any point if desired.

Nutrition isn’t one-size-fits-all, and sustainable progress doesn’t come from generic or surface-level insights. If you’re looking for a registered dietitian who delivers science-backed care grounded in real life, I’m here to help. 

We both want the best for your patients. Let’s make their nutrition part of that standard.
