A Mastermind for Pediatric Practitioners

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

Are you ready to gain traction in your pediatric-focused business?
Finally, hunker down and identify your zone of genius?
Stand out in a crowded industry?
Identify your brand strategy?
Translate your expertise into revenue?  

You’ve been working hard to make it successful and profitable, but you dream of bigger things. A specialty niche expertise. 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.  

But do you have what it takes to get to the next level?  

Let’s face it, what your business could be is exciting, but it’s also scary.  

So intimidating, you may be putting off that next step. But what if...

  • You had a clear cut business idea, brand and marketing strategy and could minimize the inherent risks associated with growing, you’d expand it and grow your business.
  • You had a posse of like-minded pediatric nutritionists, you’d feel supported, at ease, confident, and inspired with new ideas and approaches, not to mention be able to fast-track your success because you’ve avoided so many mistakes along the way.
  • You knew your zone of genius, brand and overall business strategy, you’d accelerate your fan base and leverage it, and share your unique point of view (and services).
  • You had a step-by-step strategy for developing your business, you’d create a business model that secured your financial success over time.

    IF you had all this, not only would you survive, you’d THRIVE with...  

  • A career that not only allows you to make a difference in this 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?

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.  

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 be accountable for your outcomes. Can you really stay motivated and own what it takes to grow a business?  

It all feels overwhelming.  

So much so, it’s easier to put your business on the back burner…for another season.      

That saying, “Just do it!” is great in theory, except when you’re putting yourself on the line.  

I was filled with fear when I was starting out, too.

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, 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 12 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 probably not being honest. 

Every single time I try something new, do something different or plough 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.  

These feelings never really go away.  

They become familiar friends on your business journey.  

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

You get comfortable with being uncomfortable.  

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

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.

Here's what past THRIVE members had to say!

"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

~ Jessica Gust, MS, RDN

“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

~ Melissa Halas

“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

“This program has made me stick to my plan of expanding my space and practice. My confidence has grown, and, despite the little inner voice that makes me doubt myself sometimes, I have Jill’s voice inside me telling me to move forward.” 

~Karen Mountjoy, RD

THRIVE helped me focus on whether or not I wanted to continue developing my business and if so, what I needed to do to make that happen. It was helpful to be in a group where all of us had different strengths and weaknesses. I learned so much from my fellow THRIVE attendees and their different approaches to making their businesses thrive. Having a mentor like Jill is invaluable. I appreciated the planned yet organic nature of how the 6 month course was set up.” 

~Sharon Wieder, RD

“I feel 100 percent more clear about what I want to do on my career path, and I feel that I have a very realistic plan and steps to get there. I am in an entirely different place than I was before starting the program, and since I wasn’t particularly happy or focused on work that was fulfilling for me, that’s a fantastic thing! Jill is at once inspirational and no-nonsense. If you are a healthcare practitioner, dietitian, or nutritionist struggling through private practice and you have more to say to the world about your work and your point of view, this is a fantastic program for you. In six months, you will have a vision, resources and a plan.” 

~Nicole Bianchi

~ Amy Reed, RDN

“I wouldn’t be where I am today without the group and Jill encouraging me to follow my passion for gymnastics nutrition. THRIVE is a great starting place for those wanting to build a practice, either brick-and-mortar or virtual. I’m so glad I got to be a part of this program and super thankful for where it helped me get in my business today.”

~Christina Anderson, MS, RD
