Philippines 2026

Operation Walk Los Angeles has breaking news:

We are happy to announce that our 2026 mission will be a return to General Santos City. This marks our third trip to the Philippines, and we couldn’t be more excited to work with our colleagues at St. Elizabeth’s Hospital and reunite with patients still waiting for joint replacement surgery.

But wait….

There’s more!

Fresh off a successful mission to Havana, Cuba, we need your help preparing for 2026.

Thanks to a generous donor, we’re running a match campaign where every dollar you give will be matched! Your $50 gift becomes $100, helping us provide hip and knee replacement surgery to patients waiting for their miracle. Help us meet our $5,000 goal. All funds raised go directly towards our mission to the Philippines in 2026.

You can change a life today. Don’t hesitate, click the button below to donate now and give the gift of mobility.
