---

I work with organizations that serve children, parents, and families and want to do so responsibly, ethically, and effectively.

My advisory services are best suited for:

• Healthcare systems and professional organizations
• Family- and child-focused food brands
• Health and wellness companies
• Media organizations and publishers
• EdTech and digital health platforms

If your work touches children’s nutrition, feeding, growth, weight, or wellness, my role is to help you navigate complexity with clarity.

What I Do as a Childhood Nutrition Advisor

At this stage of my career, I do not work on an hourly or task-based basis.

Instead, I serve as a strategic advisor—providing guidance, perspective, and clinical judgment to help organizations make sound decisions that stand up to both science and real family life.

As an advisor, I support clients with:

• Nutrition and feeding strategy
• Parent-facing messaging and education
• Product and program development
• Claims review and risk awareness
• Ethical considerations related to child health and weight
• Alignment between evidence, messaging, and real-world impact

I advise. Your team executes.

How Advisory Retainers Work

Advisory relationships are structured as monthly or quarterly retainers, designed to provide consistent access to my expertise while protecting both scope and time.

Typical Retainer Includes:

• One monthly strategy call (60–90 minutes)
• Asynchronous review of materials (up to an agreed limit)
• Strategic guidance and feedback via email or shared documents
• Thought partnership on high-stakes decisions

What’s Not Included:

• Copywriting or content creation
• Project management
• Day-to-day execution
• On-call or unlimited access

This structure allows for focused, high-impact work without scope creep or burnout.

Advisory Focus Areas

Clients typically engage me as an advisor in one or more of the following areas:

1. Brand & Messaging Advisory

Ensuring nutrition and health messaging is accurate, responsible, and parent-appropriate—especially in sensitive areas such as weight, growth, and feeding.

2. Product & Program Development

Guidance on the development of products, tools, or programs intended for children or families, with attention to long-term health impact and unintended consequences.

3. Risk & Ethics Guidance

Helping organizations identify and reduce potential harm related to restrictive messaging, weight-centric approaches, or misaligned wellness strategies.

4. Thought Leadership & Credibility

Advising on expert positioning, educational content direction, and alignment with current best practices in pediatric nutrition and feeding.

Engagement Terms

Advisory services are offered through monthly or quarterly retainers and are designed for organizations seeking ongoing strategic guidance rather than short-term or task-based support.

Engagements are offered on a minimum 3- or 6-month basis and represent a meaningful investment, reflecting the scope, level of involvement, and strategic nature of the work.

All advisory relationships are customized to ensure clarity, mutual fit, and long-term impact.

Why Organizations Work With Me

I bring:

• 34 years of experience in pediatric nutrition and feeding
• Deep understanding of both clinical evidence and family dynamics
• A whole-child, non-diet approach grounded in research
• Experience translating complex science into practical guidance
• A strong commitment to minimizing harm in child health messaging

My role is not to chase trends—but to help organizations make decisions they can stand behind long-term.

From Speaking to Advisory Engagements

Many organizations first engage me through a keynote, training, or internal presentation related to my whole-child nutrition framework. Advisory relationships often follow, allowing teams to apply whole-child principles more deeply across their work.

Inquire About Advisory Services

• Your organization
