John Rasla, DO

West Virginia School of Osteopathic Medicine

Dr John RaslaDeeply affected by his grandfather’s diagnosis of late-stage cancer, John decided to pursue a medical career, and challenged himself educationally to prepare for that career by building a solid science foundation. John completed his undergraduate studies at Northeastern University, earning a B.S. in biology in 2012.

Prior to entering medical school in 2015, John explored several medical specialties by volunteering at local West Virginia hospitals, where one opportunity in particular exposed him to a world that captured his interest: radiology.

He has worked in his family’s pizza business, tutored students in Elementary Arabic 1 &2, and worked as a research technician at the Dana Farber Cancer Institute in Boston. John has a long history of volunteerism: summer camp leader, West Virginia flood relief efforts, and Shriner’s Hospital for Children fundraiser, to name a few. John’s hobbies include fishing and tennis.

Georgios Sideris, MD

University of Athens School of Health Sciences

Dr Georgios SiderisWhen Georgios was a teenager in Greece, an episode involving radiologists’ conflicting assessments of his mother’s mammogram bewildered him. This experience greatly shaped his interests once he began medical school in 2009. During his student years, he spent a one-month observership in Pediatric Radiology at the Children’s Hospital of Philadelphia.

After medical school, he was awarded a post-graduate clinical scholarship, and spent 4 months rotating through Interventional Radiology, Diagnostic Radiology, and the ICU at a hospital in Greece. He served as a medical officer for the Hellenic Navy. In 2017, Georgios entered a post-doctoral research fellowship in Interventional Radiology at Johns Hopkins, and in 2018, he entered his Internal Medicine preliminary year at Montefiore Medical Center in the Bronx.

He loves the theater, the arts, and singing, and acted in his medical school drama club’s musical.

Amninder Singh, MB,BS

All India Institute of Medical Sciences

Dr Amninder SinghBorn in Abohar, India, Amninder does not come from a family of medical professionals. His interest in medicine was piqued when, as a child, he had his first interaction with diagnostic imaging, and was awestruck by the idea of “seeing” beyond human capabilities.

He entered medical school in 2012, during which time the role of radiologists inspired him to know and understand more about the specialty. In 2017 and 2018, Amninder spent two away rotations at the Cleveland Clinic, and an away rotation at NIH in Bethesda, Maryland. He has co-authored peer-reviewed journal articles, and poster and oral presentations. He feels that diagnostic radiology is at the forefront of technological advances in medicine, and he is very interested in cardiac imaging.

In his spare time, Amninder enjoys getting close to nature, especially hiking, trekking, and cycling. Ask him to tell you the story about his getting stranded during a trek in the Himalayan forests at 15,000 feet!
