Professional Mentoring

Do you work in the pediatric and family nutrition space?

Is your healthcare career as fulfilling as you want it to be

Do you want to start a side hustle or move away from clinical nutrition?

Do you have an existing business but want to offer more resources and increase your revenue

Do you want to stand out from the crowded nutrition space and be known for your ideas?

If you are nodding your head YES to any of these questions, you’re in the right place!

I offer resources, trainings and professional mentoring to pediatric and family-focused healthcare professionals.

The Power of Professional Mentoring

Hello! I’ve been a dietitian and pediatric nutritionist since 1990 and started my own business venture in 2008. As a self-employed dietitian of almost 15 years, I consider myself an entrepreneur.

I have blazed the trail of private practice (twice!), have published 5 books, get paid to speak, and I’ve built a nutrition school for parents called The Nourished Child®.

I serve as a nutrition consultant and advisor to child-focused start-ups and companies and enjoy spreading my philosophy about childhood nutrition with other healthcare professionals, parents and organizations on the stage.

A thought leader and speaker since 2010, I’ve spoken internationally, landed a TEDx talk, and am a sought-after media dietitian.

Because I have “been there, done that,” many pediatric and family-focused nutrition professionals request me as a professional mentor to guide them on their own journey of growing their businesses, expanding their thought leadership, and working with families.

As a professional mentor, I share my experiences and business insight through a variety of programs. 

Explore the different options to work with me below (use the drop down tab to get the details)!


Skip the Mistakes!

Taking the next step in your career can be pretty scary. I know! I’ve done it several times… and I’ve made my fair share of mistakes along the way.

But there’s no getting around the inherent fear of starting something new. Or the anxiety of taking a big step in your career or business. Or making a big investment.

Yet, often, this is EXACTLY what needs to happen in order to grow. Unfortunately, our mindset and self-imposed obstacles can get in the way.

The good news? A seasoned entrepreneur and professional mentor like me can help you skirt the major mistakes, wrangle the mindset issues, and get on a strategic path for business growth.

You don’t have to wonder if you’re making the right decisions, managing your business in the most efficient ways, or setting yourself up for future success.

With me on your side, mentoring you, those big business steps are much less scary and much more strategic.

Let me help you start or grow your nutrition business!  

This 6-month business mentoring program offers 28 CEUs.

THRIVE: A Mastermind for Pediatric Healthcare Practitioners is designed for the family and pediatric practitioner who has been independently working in the childhood and family space. She (or he) wants to start a business or accelerate an existing business’ growth, while boosting revenue and sharpening his or her influence.

Whether a private practitioner, blogger, online business owner, speaker or consultant, this program brings together smart, creative, experienced professionals to share ideas, strategies and experiences so that business growth accelerates, revenue swells, and influence expands.

As an independent professional, you know how hard it can be to make big decisions in your business, not to mention how lonely it can be as a solo-preneur.

THRIVE takes the best business ideas and the power of a collective “mind” to help you grow and develop your business model and next business move.

Whether you are starting your business, expanding your practice, or venturing into a new revenue stream, building is easier when you have a professional mentor like me at your side.

Plus you’ll have the support, guidance and accountability you need to succeed.

What You’ll Get from THRIVE

Facilitated by me, a 30-year veteran in pediatric nutrition and one of the “original” business owners in the field of pediatric nutrition, THRIVE meets in group sessions, one-on-one strategy sessions, expert calls with business entrepreneurs, and an in-person weekend retreat.  

Throughout our regular interactions, you’ll get collaborative feedback, inspiration, guidance and support to take your career and business to the next level.

You, my friend, will move your business forward with growth-worthy ideas, imaginative business additions that serve your clientele, and a clear point of view that propagates your influence.

THRIVE is a 6-month program beginning in January of each year. Get more details about the program to know when the next enrollment phase begins. Offers 28 CEUs.

“Working with Jill in the THRIVE Mastermind was one of the most invaluable business investments of both my time and money. Before I had the opportunity to work with Jill and collaborate with like-minded colleagues, I felt overwhelmed with ideas and unsure how to best execute an actionable plan that would keep me moving forward in my business as a private practice dietitian. Jill provided a safe and nurturing community, valuable resources, and ongoing support and accountability that allowed me to become crystal-clear on my entrepreneurial journey. She took the time to get to know me and my business and provided insightful feedback, guidance, and advice that helped me clearly understand how to refine my messaging for my target audience. Her experienced perspective and leadership through this mastermind was pivotal in accelerating my online presence and business, allowing me to grow exponentially and expand my reach to those I have been so eager to help.”

Let me help you keep the momentum in your business going strong. STRIVE is a 10-month mastermind.

STRIVE is a Mastermind for the pediatric or family-focused nutrition professional who is established in business and is looking for support, accountability and strategy support to sustain ongoing business momentum.

This 10-month mastermind is perfect for you if:

  • You’ve completed my 6-month program, THRIVE.
  • You’ve been running a business and want to harness your momentum and put some serious cash in the bank.
  • You want to be part of a collective of nutrition professionals who are motivated, accomplished, and vested in the growth of the pediatric nutrition business field.
  • You want to crush 6-figures.

In STRIVE you will be able to:

  • Refine your business strategy, systems and money-makers.
  • Develop a strategic mindset about your business, offerings and services.
  • Break down the barriers that prevent you from growing.
  • Be surrounded by ambitious nutrition professionals who generously share insight, ideas and open doors.
  • Be coached by me, a multiple 6-figure business owner.

If you’ve made investments in your business and had some success, you may find you’re going it alone. When things start to lull or get crazy busy, you begin to stall or get mired in overwhelm. Or worse, you regress to old, counterproductive thinking, rely on a “work more and harder” approach, and lose sight of effective processes and strategies.

This is a recipe for losing your momentum.

Let’s not let that happen! Check out all the details about STRIVE and book a call to chat about it. Rolling enrollment is available.

ARFID Training for nutrition professionals

Avoidant Restrictive Food Intake Disorder (ARFID) is on the rise in children. It’s a form of extreme picky eating. As a nutrition professional, you may encounter more of these kids in your practice.

Children with extreme picky eating present with a variety of health concerns. Often, they have a very limited diet, nutrient deficiencies, fear and anxiety associated with eating, and feeding and parenting dynamics that need to be addressed. The extent and intensity of these cases can be highly variable.

This professional group program is for nutrition professionals who want to develop deeper expertise in working with children who experience extreme picky eating, or ARFID, in the outpatient setting or private practice.

Generally, participants join because they want to:

  • Develop into a stronger and more confident practitioner in the area of ARFID
  • Be a resource to families and other healthcare practitioners in your area for this condition
  • Grow and develop this area of your business

If training in this area is something you’d like to develop in your practice, get on my professional newsletter list to learn more.

Because each case of extreme picky eating requires an individualized approach and a deep set of clinical and counseling skills.

Helping families with bigger kids workshop for nutrition professionals

If you want to move away from diets and diet culture toward a holistic, whole child model for helping families develop the health behaviors that support a lifetime of health, at any size, then this is the workshop for you!

In this workshop, you’ll explore:

  • The Whole Child Health model which focuses on physical health and emotional wellbeing
  • Whether weight/growth is really a concern and how to know
  • When weight isn’t a concern, how to support a frustrated and concerned parent
  • When weight is a health concern, how to pinpoint the contributing factors and help families move to a better place
  • How to reverse/refine the factors that contribute to excess weight
  • What to do if you can’t improve health or lifestyle habits
  • How to facilitate realistic and helpful goals, without doing harm

After running a pediatric nutrition private practice in which over 50% of my clientele were families with larger children (with and without health concerns), I know that how you detect the unique challenges of kids who live in larger bodies, meet families where they are, and help them improve their lifestyle will differentiate you from the “fix weight” model while truly helping parents take a holistic and helpful “pro-lifestyle” approach for the whole family. 

I’ve prepared this special workshop to help you find your footing with families of bigger kids so you can feel confident and good about helping them.

Because every parent deserves to feel confident about raising a larger child, and every kid deserves to feel good about themselves, at any size.
