About Us



Child Health & Resilience Mastery (CHARM) is a qualifying charitable organization based in Nogales, Arizona. We provide unique strengths- and evidence-based experiences, education and training, and health-promoting resources to improve well-being, and strengthen resilience, 

especially for vulnerable children and families.  


Unique Experiences & Resources

We offer evidence-based ways to improve children’s health outcomes and boost their resilience. Our programs incorporate approaches such as Dr. Ginsburg's “seven C’s" model for resilience, to nurture skills such as: 

coping, confidence, connection, character, contribution, control and competence. We've also added a few C's, including creativity and culture! 

We host fun mini-camps for children, provide workshops for families, and partner with like-minded nonprofits and businesses to support educators and health providers in our communities. 

In addition, we curate a virtual Hub of Love of resources and lovingly open our doors at CHARM's Hub of Love, located at Hacienda Corona de Guevavi, to collaborate with the surrounding community, local schools, and nonprofit organizations aligned with our mission to provide resources that cultivate wellness and resilience.
