He practiced traditional internal medicine from 1997 to 2007 with a large part of his practice doing inpatient as well as HIV medicine. He also spent time moonlighting in Emergency Rooms and Urgent Care. From 2005 to 2007 he practiced part time at Oregon Health and Science University as an HIV consultant. In 2007 he switched to full time hospital medicine and, as his children were growing older, he started to spend more time working overseas again. Most of his experience at that time was in India, but later in Haiti, Uganda and most recently in South Sudan. His interest in point of care ultrasound began during his residency but there were no mentors and he was not aware of any formal training for internists at that time, so struggled using it, trying to teach himself. Finally in 2016 he decided to embark on a year long fellowship with the Ultrasound Leadership Academy. This program focuses on people that not only want to learn point of care ultrasound, but also ones interested in being instructors and leaders in the field. POCUS help his practice tremendous, especially in many of the resource limited settings he was practicing in.
