Daniel Boctor – Park Clinic Coordinator

Growing up in Cairo, Egypt until the age of 18 showed me how much we have to offer, even in the absence of medical degrees. My passion for medicine drives me to be exposed to as many different people as I can, in hopes of offering them opportunities to better their lives. I strongly believe that healthcare providers have the power to ensure the sustainability of humanity. My ability to communicate in four languages reinforces this passion. I am a fourth year student at UCSB in the College of Creative Studies, majoring in Biology. I am heavily involved in retinal cell biology research on campus, and I aspire to one day become as good a clinician as those who volunteer for Doctors Without Walls

Matt Sumethasorn – Street Teams / Special Missions Coordinator

Matt Sumethasorn is a graduate student at UCSB. He is interested in finding the genetic and environmental factors that influence ethanol related behaviors in fruit flies. Matt joined Doctors Without Walls as a way to foster personal growth while at the same time fostering growth in our own community. He quickly found Street Teams to be his favorite branch of DWW, allowing a more personal interplay with both providers and patients alike. Matt hopes to to bridge the gap between our patients and our organization, so that we can provide better care to those who need it.
