Empowering Dentists Through Real-World Learning
Where Clinical Mastery Begins — In Practice, Not in Theory
At International Focus on Healing (INFOH), we believe that what you repeat, you remember — and nothing stays with you more than treating real patients, in real time, under expert supervision.
Founded by internationally recognized educators Dr. Antonio Sanz and Dr. Gayle Fletcher, INFOH provides advanced, CE-certified dental training with live patients in Guatemala City. Our courses were designed for professionals who want more than theory — they want lasting transformation.



Our Courses
From Classroom Concepts to Confident Clinical Execution
In most continuing education programs, you sit through lectures, watch demonstrations, and return home with unanswered questions. At INFOH, you treat real patients — not models, not simulations — gaining the skills, confidence, and decision-making power you need to succeed on your own terms.
Whether you’re a recent graduate in need of hands-on experience, or a specialist looking to elevate your practice, our immersive curriculum delivers tangible results, starting the moment you return to your office.
