To our community of healers, students, and practitioners,
We are thrilled to announce the reestablishment of a historic partnership between the International Institute of Iridology and the School of Natural Healing.
This collaboration marks a return to our roots. Dr. David J. Pesek’s first distance education courses were in partnership with the School of Natural Healing. Dr. Pesek was invited to continue the teachings of Iridology previously offered by their founder, Dr. John R. Christopher, who utilized Iridology as a vital method of assessment throughout his life’s work.
Today, we honor that history by combining the “Art and Science” of Dr. Pesek’s Holistic Iridology with the world-renowned herbal education of the School of Natural Healing.

Continuity and Quality You Can Trust
We understand how deeply our students value the integrity of Dr. Pesek’s teachings. We want to assure you that while the administration has a new home, the education remains unchanged:
- The Same Curriculum: You will have access to the same high-quality online courses Dr. Pesek developed.
- The Same Prestigious Certification: Students will continue to earn their Holistic Iridology Levels I, II, and III certifications and diplomas, maintained at the highest level of excellence.
- Enhanced Learning: Students now have the unique advantage of seeing how specific herbs and foods directly support the systems revealed through Iridology.
Your progress, access, and certification standing are not changing and remain fully protected. No action is required on your part.
Announcing Exclusive Live Training
In addition to our online offerings, we are proud to offer live classes led by Jo Francks, MH, CCII-3,—the only instructor in the United States personally sanctioned by Dr. Pesek to carry his teachings forward. These live sessions provide an incomparable opportunity to study this healing art under expert, authorized guidance.
Honoring the Vision
The School of Natural Healing is honored to care for Dr. Pesek’s students as they continue their educational journeys. By bringing these two institutions together, we are not just teaching assessment and application—we are providing a complete path for the modern practitioner.
We invite you to join us in this new chapter.
