Within 60 days, my client had dropped over 30 pounds, had her energy back, had balanced her blood sugar, and was telling everyone how wonderful she felt and how amazing I was in getting her on the right track.
When people in my community learned about this new path for me, they started to refer to me as "the hormone expert".

There really is nothing like NEPT.
I've been through a lot of schooling, certification programs, marketing training, etc, to the tune of multiple 5-figures in my career. But I've never seen anything nearly as comprehensive as NEPT. Dr. Ritamarie doesn't hold back in sharing her expertise, people skills, and clinical knowledge. The course covers everything you need to know to deliver health transformations to your clients, from physical exams and history taking to conventional and functional lab tests, to genetics and coaching skills. She starts with biochemistry and dives deep into how she incorporates it clinically. Then, she provides worksheets and resources that you can use to market your practice or even apply to your current clients right away. I love the energy of the community, especially on the support calls. She even teaches and mentors you through niche selecting and building your practice. Everyone really wants you to succeed. There really is nothing like NEPT. If you're on the fence, do it!

I felt like a poser
NEPT was exactly what I needed to get my confidence as a coach. I love the program. I have learned how to assess my clients' problems and I get step by step details on how to get to the root of their problems in my NEPT group.

Finishing the NEPT program has given me a sense of accomplishment and confidence.
It was a process of a lot of personal growth as well as professional education. I still have dreams to get to that next level, but I have more confidence and ability and am willing to step out of my comfort zone and move into the discomfort of trying to go further.

Before meeting Dr. Ritamarie I had a flailing practice, I had education, credentials and knowledge, but I didn't know how to grow my practice. Now, after joining Practice Accelerator I have a waiting room practice.

Joining NEPT is the best investment I've ever made
Joining NEPT is the best investment I've ever made, both with knowledge, getting very in depth with the material, keeping on top with current research, and the support from the people in the program. Now I have great confidence when I consult with my clients, which is huge

About Dr. Ritamarie Loscalzo
Meet the Founder of the Institute
of Nutritional Endocrinology.
Over the past 30 years, I’ve learned that the secret to having a steady stream of new clients eager to regain their health is to provide an empowerment system that gets the results they crave.
I invested thousands of hours and hundreds of thousands of dollars on my education. I realized that to have a successful and thriving business and impact thousands of lives, it wasn’t enough to just work on my clinical skills. I also needed to learn how to get people in the door and keep them there long enough to truly integrate the healthy lifestyle changes I had suggested.
And now, with decades as a functional health and wellness practitioner under my belt and lots of trial and error I have figured out how to deeply impact lives AND make a good living doing what I LOVE to do.
That’s why I want you to join my Nutritional Endocrinology Practitioner Training (NEPT) - so I can personally walk you through my system that’s helped change thousands of lives.
It’s for you if you know you have a lot to share and you need a proven formula for doing it in a way that feeds you physically and emotionally, with ease and grace.
NEPT employs a blend of functional medicine assessments, biochemical testing, nutrient evaluation, and comprehensive diet, fitness, mind-body, and lifestyle skills development that empowers you to feel confident about your ability to help the clients with even the most complex health challenges to get the results they are seeking.
Now it’s time to get started. Together we can transform how healthcare is practiced.
