THRIVE A Mastermind for Pediatric Practitioners  

Who Want to Accelerate Business Growth, Boost Revenue, and Sharpen Their Influence 

APPLY NOW!

Are you ready to up-level your pediatric-focused business? Maximize your efficiency and accelerate growth? Be known as an influential authority? Generate income like never before?  

You’ve launched a business. You’ve been working hard to make it successful and profitable, but you dream of bigger things. A bigger practice. Bold ideas you want to share with the world. A product you want to sell. The next “layer” you want to add to your business model. Or your next big step along your career path.  

But do you have the tenacity to take charge of your business and get to the next level?  

Let’s face it, big dreams are exciting, but they are also scary.  


So much so, you may be putting off that next, essential step.

  • IF you were certain of the best business strategy and could minimize the inherent risks associated with growing, you’d expand your private practice and grow your online business.
  • IF you could tap the brain trust and support of other like-minded pediatric nutritionists, you’d feel at ease, more confident, and be inspired with new ideas and approaches.
  • IF you knew how to accelerate your fan base and leverage it, you would have a community with which to share your unique point of view (and services).
  • IF you had a step-by-step plan for accumulated business development, you’d create a growth-minded business model that secured financial success over time.
  • IF you had all this, not only would you survive, you’d THRIVE.  

I bet you have your next step in mind. I bet you can feel it…and even taste it.  

  • A career that not only allows you to make a difference in this world for kids and families, but one that also puts you in the sweet spot of satisfaction -- emotionally and financially.  
  • A career that pays you what you are worth.  
  • A career that you manage, not one that manages you. 

So, what’s holding you back? Fear and doubt get in the way… You know this dream career is possible. In fact, when you allow yourself to dream about your future, you know the possibilities are endless. The sky [really] is the limit to what you can do! But, the reality is, you’re worried.  

Worried…  

About your competition. The nutrition space is getting crowded, voices are getting louder, and the platforms are bigger. How will you stand out?  

About your business savvy. You don’t have a business degree. The last thing you want to do is invest more of your precious time and hard-earned money into something that might not work.  

About your time. You’re already strapped with work. How will you fit in more work?  

About your ability to commit to the work. Can you really stay motivated and devoted to what it will take to level up, grow and thrive?  

About your ability to make the hard decisions. To get started. To make the move. To say no. To say YES!  

It all feels overwhelming.  

So much so, it’s easier to pack it in. To look the other way. To put this next step in your career on the back burner…for another season.  

Fear, anxiety, overwhelm…what you’re feeling is real.  

It really feels like a ENORMOUS step!  

That saying, “Just do it!” is great in theory, except when you’re putting yourself out there -- your business and your reputation… on the line.  


I was filled with fear.

I was a fear-filled dietitian in 2008. I had been a full-time mom for 9 years, having turned in my lab coat in 1997 when I had my second child. In 2007, as my youngest entered preschool, I could see my future. A future of volunteering in the school lunch room and on field trips, giving free talks to local groups in my town, of doing laundry every day, grocery shopping and cooking, going out to lunch with friends, and maybe playing some golf.  

Not a bad life.  

Although these were noble, valuable things to do with my life, I knew in my heart, these things would not sustain me long-term. And, I didn’t want to start a business journey AFTER my kids launched.  

I wanted to be in the position to scale up when they left the nest. 

So, I spent 2007 learning how to start a private practice. 

I read every book the nutrition industry had on the subject at the time. I took the study guide tests. I read the online resources from the Small Business Association. I did teleconference trainings, lurked on the Nutrition Entrepreneurs Dietetics Practice Group for every business tidbit I could learn, and slowly planned my business.

We moved to Nashville at the end of that year and my son entered Kindergarten. After settling in, I knew it was time to take the leap. In May 2008, full of anticipation, fear and doubt, I opened my private practice. I had my first official client on July 3, nearly two months later.

Since then, I have taken many risks, and have had my share of failures and successes.  

I’ve launched and operated two private practices. I’ve hired and fired. I’ve been a freelance writer, a blogger for almost 10 years, a podcaster, and a consultant (all wins!). I’ve been a legal expert (yuck!). I’ve helped companies develop, launch, and market new products. I’ve developed, launched, and marketed my own products. And, I’ve been on national, international and TEDx speaking stages sharing my thought leadership, too many times to count.  

Through it all, I still experience fear and doubt. And if anyone tells you they don’t, they’re lying to you.  

Every single time I try something new, do something different, or plow ahead into an area where few have gone, I feel that familiar tummy swell of discomfort. Doubt, fear, and a desire to run in the opposite direction, set in.  

My friend, fear, doubt, and angst…they never really go away.  

They become familiar friends on the journey of growth and development.  

You learn to live with them. Deal with them. Keep your head down and keep going.  

You get comfortable with being uncomfortable.  

Yes, I have forged my own career. On my own time, on my own dime, and with little help, support or guidance.  

Often, I found myself in a position with no clear indicator of whether something would fly or tank.  

Yes, I learned how to run and scale up my business the long and hard way. While my recognition as a childhood nutrition specialist grew quickly, cracking the six-figure mark took much longer. The truth is, it all took thoughtful planning and hustle.  

I don’t want it to take that long for you.  


What if? 

  • You could take control of your next steps feeling confident, calm, and clear?  
  • You could grow your business quickly and smartly, with a clear-cut path to get you there? 
  • You could steep your unique point of view into your brand and business from top to bottom?  
  • You could sharpen your influence and ensure future demand of your time and talents? 
  • You had a brain trust of smart pediatric nutritionists, an experienced authority in the field to lead and support you, and the structure and accountability you need to make your dreams come true?

Here's what past THRIVE members had to say!

~ Jessica Gust, MS, RDN

~ Amy Reed, RDN


"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."  

~ Crystal C. Karges, MS, RDN, IBCLC


“Coaching with Jill Castle really helped me hone in on my marketing messages and provided an actionable framework to accomplish my professional goals for the quarter. Jill provided clear and concise direction, honest and candid feedback and generously shared her expertise and guidance to help me get my product launched and to meet my sales goals!” 

~Katie Ferraro, MS, RDN 


 “Jill has a natural talent for helping others efficiently drill down to what is important and keeping them on task. Her know how regarding feeding children and their families, and all that goes into beginning and growing a business helped me stay focused and assured that I was working on the right things to achieve my goals. She is a pleasure to work with!” 

~Jane Henley, MS, RDN


"THRIVE has helped me see beyond the day-to-day of working with clients. It has expanded my mindset and opened a world of possibilities in the realm of pediatric nutrition.  

I really liked all aspects of this program: the 2-hour sessions were well-balanced with instruction, hot seats, and feedback. I also really enjoyed and was inspired by your guest speakers. The individual strategy sessions are always super helpful and help me focus. And the retreat was amazing!  

Although I have a long way to go, I have much greater insight into what is possible."

~ Susannah Wallenstrom, MS, RDN


“I would definitely recommend this Mastermind experience to other RDs.” 

~ Karen Glander, MS, RD


“Jill helped me see that I do have a lot to offer and that has given me more confidence in approaching other businesses to offer my services.” 

~ Amy Reed, MS, RD


“When I started the program, I knew what I wanted to do but felt stuck. I joined the THRIVE beta group, knowing that this was decision time. I would either continue to pursue private practice or move on to something else! With your help and insight, I’ve been able to set goals and envision what my next step will look like and the steps I need to take to get there.” 

~ Laura McDaniel, MS, RD
