Internal Medicine Faculty

Jessica Amos, DO

Jessica Amos, DO

IM Associate Program Director

Medical School: West Virginia School of Osteopathic Medicine

Completed Residency: Charleston Area Medical Center, Charleston, WV

Professional Interests: I have always been passionate to care and serve the community in which I grew up in. However during residency I quickly learned that academic medicine would also be an integral part of my future as an Internal Medicine physician. Academia not only allows me to have the ongoing opportunity to advance my own knowledge of medicine and patient care but also provides me the avenue to use that knowledge to educate the next generation of physicians. My role in leadership as Associate Program Director has also allowed me to provide continuous program development and work closely with residents to provide and meet their needs to become excellent physicians.

Hobbies / Interests: Weekend trips to Lewisburg area for outdoor adventures and R&R time with family and friends.

Strengths of Training at CAMC: Innovation. CAMC not only provides excellent education but we also work continuously with residents and use their input to help with ongoing program improvement. We train some of the best general Internists but also offer advanced training in fellowships that is growing every year.

Life in Charleston: Even though Charleston is the largest city in WV and has the typical variety of restaurants and activities, it still offers that “small town” feel of community.

Strengths of Training at CAMC: The culture of CAMC (and West Virginia) is welcoming and warm. Within the program egos are dropped and there is a sense of family.

Attempts at minimizing stress and having a clinical learning environment that is not only focused on patient centered care but also resident education across the institution.

Life in Charleston: The proximity to outdoor focused activities is incredible. Within a 1 hour drive you can be whitewater rafting world class rapids on the New River Gorge, trail running/hiking some of the most beautiful areas on the east coast, and skiing in the winter. In addition, we are 3 hours away from multiple cities (Pittsburg, Columbus, Lexington, etc.) that gives the opportunity for weekend trips. The city has excellent running opportunities including a path on the river that passes in front of the state capital. The most important positive about Charleston though is the people. Welcoming, warm, and helpful are just a few of the adjectives I would use to describe them.

Strengths of Training at CAMC: Health care is not a top priority of some individuals in West Virginia, thus we get to see disease coming in at all stages without prior treatment. This helps to understand natural course of diseases. Residents are still front line to manage patients, not standing behind rows of other learners.

Life in Charleston: Minimal traffic so you can get around easily. Safe for family. In normal year (non covid) have a lot of family friendly festivals to attend. This state has a lot of outdoor activities to do that are not far from Charleston.
