About us


Timmy Global Health expands access to healthcare and empowers students and volunteers to tackle today’s most pressing global health challenges. To achieve this goal, Timmy sends medical service teams to support the work of international partner organizations and channels financial, medical, and human resources to community based health and development projects. Through our work, we strive to empower volunteers to lead the fight for global health equity and help deliver the promise of a healthy future – one patient at a time.


Timmy Global Health was founded in 1997 by Dr. Charles (Chuck) Dietzen, a pediatric physical medicine and rehabilitation specialist. After working in a number of international settings, including with Mother Teresa, Dr. Chuck was inspired to serve more communities by engaging the next generation of healthcare leaders. The organization was named after Dr. Chuck’s brother Timmy, who passed away in his infancy. The organization is a legacy to both Dr. Chuck’s brother and family, as well as a tribute to all the patients around the world that deserve quality healthcare.

Timmy Global Health is an independent, nonpartisan 501c3 organization that does not endorse or oppose any political party or candidate.
