More About IFMNT Training Programs

Functional Medicine works best when nutrition is applied with clinical precision, depth, and discernment. Yet many healthcare professionals are asked to implement nutrition-driven strategies without having received the level of training required to do so efficiently or confidently—especially in complex, chronic cases.

Integrative and Functional Medical Nutrition Therapy (IFMNT) training exists to change that.

This advanced training is designed for licensed and credentialed healthcare professionals who use nutrition within their scope of practice and want to strengthen clinical decision-making, streamline care, and improve outcomes across a wide range of patient presentations.

With more than 550 hours of advanced, clinically focused education, IFMNT is not introductory or protocol-based training. It is a comprehensive system that develops the practitioner’s ability to assess, prioritize, and individualize nutrition interventions—reducing guesswork, improving efficiency, and supporting better long-term results for both patients and practices.

Practitioners who complete IFMNT training consistently report greater confidence, clearer clinical reasoning, more effective case management, and stronger collaboration with other members of the healthcare team. These skills translate directly into improved patient outcomes, greater professional credibility, and increased practice sustainability.

Developed and led by Susan Allen-Evenson, RDN, LDN, FMNS, this program reflects more than 30 years of clinical experience, teaching, and mentorship within the Functional Medicine space. The evidence-based curriculum is intentionally structured for working professionals, offering both live and pre-recorded learning options. All live sessions are recorded, allowing practitioners to engage deeply with the material while maintaining full clinical schedules—without the time and expense of constant travel to in-person events.

In addition to the comprehensive Certificate of Training pathway, all IFMNT modules are available for individual enrollment, either as live training series or pre-recorded courses. This allows practitioners to customize their education based on experience level, scope of practice, and immediate clinical needs.

Participants gain access to a robust collection of clinical tools, protocols, handouts, and customizable forms designed for direct implementation in practice—not theoretical learning.

A defining feature of IFMNT is its live clinical discussion, mentorship, and private professional community. This collaborative environment allows practitioners to refine clinical reasoning, explore nuanced patient cases, and learn from colleagues across disciplines. The result is not just more knowledge, but better judgment—an essential skill in advanced Functional Medicine practice.

Flexible payment plans are available, and group discounts may be offered upon inquiry.

A Certificate of IFMNT Training is optional and includes a final exam process. All participants receive a Certificate of Completion for each module they complete regardless. Practitioners who earn the Certificate of Training are eligible for inclusion in the IFMNT Practitioner Referral Directory (in development).

These days, there is so much information available about alternative healing modalities including supplements/herbs, nutrition, fitness, alternative/functional medicine, mind-body practices, etc. It’s hard to sift through it all and know what to trust or how to use in practice. Next Level Functional Nutrition offers you reliable research and clinical experience based information and training that will help you stay on the leading edge of your profession and, more importantly, empower you to more fully and effectively serve the clients you work with.

Our program is suited to Registered Dietitians and Professional Nutritionists, along with any other credentialed healthcare clinicians who wish to add a nutrition focus to their practice, such as: MDs, DOs, RNPs, RNs, DCs, DOMs, etc. Due to the heavy emphasis on the clinical application of our training, registration is limited to licensed or professional healthcare clinicians (as noted above) who have at least a 4-year undergraduate or a 2-year Master’s, science-based degree.

Note: although we gladly include non-nutritional medical professionals in our training programs, we encourage you to partner with an IFMNT Nutritionist (also called a Functional Nutritionist) for the maximum application of nutritional services and to ensure the most successful outcomes with your patients. The value of this training is that you appreciate the importance of IFMNT nutrition as a vital component of patient care and that you can work effectively as a team to provide the most comprehensive care to those you serve

Founder & Mentor, Next Level Functional Nutrition

Thirty years ago my mentor in the field of Functional Medicine helped me realize there was more to nutrition than I learned in my traditional training. Enticed, this led me down an exciting path of discovery that transformed me, both personally and professionally. I hear often from my clients, “No one else has ever told me this” and “I feel better than I have in years!”

Enthralled with my success and career growth using IFMNT, I realized I just had to share this with my peers. This vision is what birthed my own mentor program almost 20 years ago, which eventually grew into the international training initiative Next Level Functional Nutrition, where noted experts join me in influencing thousands of healthcare practitioners to incorporate Functional Nutrition into practice.

My mission is to see nutrition considered the very cornerstone of health and to have my colleagues experience no less than the level of respect and success they so deserve, yet often struggle to have. I truly believe Functional Nutrition is the key!

I am proud to be considered one of the pioneers in our global healthcare transformation. Join me on this amazing journey and see for yourself how much more you can grow and make a difference yourself!

“With Next Level Functional Nutrition and Susan’s experience and knowledge, I have learned without having to leave my home and with the support of other nutritionists whom also serve as mentors…even as they are learning, too.”

Lynsey Argota, RDN
This course has literally taken my career to the next level.  The information is up to date and on the leading edge.  A single class would not do you justice as the body is so interconnected.  The complete certification is priceless and I wish I would have done it sooner.
Thank you so much.  I’ve completed one year of education and am ready for more!
Paulette Weber RD, LD/N, CLT

My assessment skills have improved tremendously. The functional lab analysis has truly amazed me – this skill alone can transform an RD’s practice! I appreciate that the sessions are recorded. To me the biggest benefit is access to the Facebook group and Susan who has been available to answer questions about individual cases.”
