Houston will always be known first as the Lone Star State's biggest energy city. But at our core, we're a medical community. This is, after all, the city of DeBakey, Cooley, and Duke. In recent months, we at CultureMap have been taking a look at charities making an impact in the community, and the list of health and wellness-related organizations in Houston, not surprisingly, is the longest one yet.

CultureMap's new Houston Charity Guide, presented in partnership with Frost's Opt for Optimism campaign, is a one-stop resource for locals looking for ways to give back — including to the health of people in the community.

Here’s a look at some Houston nonprofits making an impact on health, healing, and wellness, from addiction recovery to curing childhood diseases and helping people age gracefully. Know of a group that should be added? Let us know.
