Dr. Arash Hakhamian is the co-founder and medical director of GGHTx. 

A Doctor of Dental  Surgery, Dr. Arash is an avid traveler, international lecturer, and global philanthropist who has volunteered with various medical missions and organizations for many years before helping establish GGHTx. As one of the only volunteer organizations exclusively for young professionals, Dr. Arash believes GGHTx was formed to allow young volunteers to travel around the world while also provide immediate medical and dental relief to the most underserved populations.

Dr. Arash explains, ”These incredible volunteer missions change both the lives of our participants and the patients they serve by allowing our young volunteers to experience various aspects of healthcare and medicine while providing a much needed service to the poorest individuals from 3rd world countries in Latin America.”

Julio Chàvez B.Eng.


Julio - by trade - is a civil engineer who has a deep love for helping people in any way he can. He is passionate about public health and creating change, which led him to become the director and project development manager for clinic ASSADE which, in partnership with DOCARE, is a clinic home to approximately 32,000 people, most of whom are indigenous farmers with very low incomes.

"I am very happy that there are more people getting involved in global health with GGHTx" exclaims Julio. "There is a lot of work that still needs to be done and it's definitely not easy, but seeing our American volunteers go overseas during their vacation time continues to give me a sense of hope and that is something I thank God everyday for." Julio has been very appreciative for all the work that has been done in conjunction with GGHTx, especially for the ASSADE clinic that was built with the sole purpose of providing medical and dental relief for all, no matter one's income, while also meeting basic US standards.

ASSADE currently employs a full-time doctor and nurse, in addition to other health and support staff, and treats on average 30-45 patients per day - seventy percent of whom are women and children. In addition to caring for acute conditions, the staff increasingly focuses on preventive medicine to better avoid certain tragic outcomes that affect the population there.   

Julio is fluent in English, Spanish, and various local indigenous tongues spoken only by few.


What makes GGHTx Different

Additional Information

“GGHTx differs from all other volunteer groups and organizations because we really wanted to incorporate a fun and adventurous tourism aspect to our mission trips where we would dedicate our mornings to changing patients' lives and then have several hours of 'vacation-time' for our participants so as to allow our volunteers to experience the amazing  extracurricular activities of each country we visit,” explains Avi. 

It is not unusual to have days where our volunteers are assisting medical staff with delivering babies at 6:30 in the morning in some off-grid rural village with chickens flocking near our feet, while only later - that same day - changing out of our soiled scrubs so that we could get ready for our latin dance lessons from our amazing salsa-dance instructors, Nancy and Jose!

- Avi Kerendian, Project Manager (GGHTx)

One of GGHTx's core values is to hope to instill in the future generations of doctors, dentists, and clinicians attending these trips a sense of social responsibility and an opportunity to gain medical/dental experience while helping reduce the great health disparities prevalent in underserved populations in countries around the world.

With that said, it is also GGHTx's priority to provide our hard-working volunteers with a safe, exciting, rewarding and unforgettable trip that will reshape their perspective and their futures! 

It is an exhausting and emotional trip and it is not for everyone, but with it comes this deep sense of fulfillment and pride that one can't just have to experience it; and that is something that I would not trade for anything. it's eternal." 

- Dr. Arash Hakhamian, Medical Director (GGHTx)
