 GeraldGrace Gerald, MD

I grew up in Charleston, SC, and Pelham, NY. My father was a pathologist and my mother is a nurse. I chose ETSU because I knew that I would be well trained as a general surgeon and still have the opportunity to pursue a fellowship if I decide to specialize. I also knew I would enjoy living in the area because of all of the outdoor activities available in East Tennessee.

MeyerJeremy Meyer, MD

I grew up in Johnson City, and never thought I would be returning here for residency. But after my interview here I realized that ETSU was unique in many ways that really appealed to me. They have a great focus on rural, broad-based general surgery and I have a particular passion for third-world missions. I believe ETSU will be a great place to prepare for my future, whatever is in store. Outside the hospital I enjoy spending time with my family. My wife and I are active people and love spending time outdoors from hiking and mountain climbing to water- skiing and snowboarding.

I returned to my hometown of Johnson City to attend ETSU College of Medicine. My favorite thing about coming to ETSU is the close-knit community and friendly atmosphere. In my spare time, I love spending time with my family and friends, playing tennis and computer games.

Pryor William Pryor, MD

I'm originally from Tennessee but I went off to school in South Carolina. Growing up near Chattanooga I am very fond of East Tennessee, and so I am very excited to be back. Of course this means I am a huge fan of the Tennessee Vols. Go Big Orange! I placed ETSU at the top of my list because of their emphasis on training the broad-based general surgeon and exposure to trauma. Two important things that will one day serve me well as an Air Force surgeon. When not in the hospital, I love to find adventure in the great outdoors or stay active by going for a long run.

Trevy Ramos, DO

I originate from Merrillville, IN. From the crossroads of America I ventured to almost heaven, West Virginia, for Medical School. I chose ETSU and ETSU chose me. It is an institution that takes pride in providing well-rounded and well-educated surgeons. ETSU puts its students first and strives to produce technically competent surgeons through early experience in the operating room.

Korsica Lassiter, MD

I was born and raised in Eastern North Carolina and had the pleasure of returning home to attend medical school.  I chose surgery as my specialty early on because of the ability to physically intervene in a patient's disease course.  I enjoy the broad-based general surgery training this program provides.  In my free time, I enjoy traveling, baking, and, of course, shopping!

I grew up in South Florida as the oldest of 4 girls.  I first fell in love with surgery when my dad (an anesthesiologist) took me to the OR with him at age 10.  I chose ETSU because I like the friendly atmosphere, broad general surgery emphasis, and the beautiful mountain scenery.  I have been very happy here so far!  In my free time, I enjoy reading, watching movies, spending time outdoors, cooking, and playing with my dogs.

Jessica Stephens, MD

I chose ETSU because of the atmosphere of cooperatively and excellence between residents of this program.  Although I believe I will specialize, (currently I like trauma critical care) I believe having a strong foundation as a general surgeon is key to any future practice.  When I am not working I like lounging around with my 2 cats, hiking, rock climbing, swimming, and pretty much anything involving the outdoors.  I look forward to all the next 5 years will bring.

Edward Gray, MD

In choosing ETSU Quillen College of Medicine, I have found both a strong residency program and a beautiful region of our country. I found that the general surgery program provides broad experience in general surgery. While I will likely pursue a fellowship and have an interest in Trauma / Critical Care, having a wide foundation is important in any surgical specialty. In my free time I enjoy mountain biking, working out, hiking, and when I am not outdoors I enjoy cooking a good meal.

In our free time we enjoy traveling, cooking, going to the lake, and spending time outdoors. For all these reasons ETSU Quillen College of Medicine is a great fit for us.

Nandita Rao, MD

I grew up and went to college in eastern North Carolina, where my dad currently practices broad-based general surgery. I guess the apple does not fall far from the tree, but I was really drawn to surgery when I witnessed the great potential for making a positive impact on people's lives. ETSU Quillen College of Medicine's surgery residency program was an easy choice because of the approachable faculty, supportive colleagues, and history of graduating excellent surgeons. When I am not working, I love to travel overseas with my family. I plan to cross a few more countries off my list before I graduate!

Jack Johnston, MD

I was raised in Greeneville, South Carolina, where my three brothers and I were always playing soccer or being active outside.  I have always enjoyed the mountains and the outdoors.  I attended Clemson University where I met my wife, Kate.  I spent my first year of general surgery as an intern in Charleston, South Carolina.  I felt that early autonomy, broad-based operative experience, and a program that serves a large population was vital to my development as a surgeon, which is what I found at ETSU.  Also, what I found was the heightened value for family at ETSU.  My wife and I enjoy attending Clemson games, hiking, traveling, and hanging out with our dog, Ruby.

Katharine Lasher, MD

I was excited to come to ETSU for my surgery residency because I was looking for a broad-based training experience with opportunities for training in a rural setting.  I enjoyed all my interactions with the residents and staff on interview day, and I loved the mountain setting of the Tri-Cities area.  My husband, Justin and I moved with our dog, Brody, into an old farmhouse outside of Jonesborough.  Currently, my free time is dominated by working on the house, but I also love cooking, reading, and      crocheting.

Mohamed Mohamed Kelli, DO

I am Kurdish and was born in Aleppo, Syria. My family moved to Germany when I was 6 years old. Then, my family immigrated to the United States about 12 years ago to pursue the "American Dream".  My goal is to become an excellent well-rounded general surgeon. ETSU Quillen College of Medicine has all the necessary resources, including the case load, mentors who are eager to teach, and supportive residents to help me become a great surgeon. I was a Biology major and played D1 soccer at Wofford College. In my free time, I enjoy outdoor activities, running, and of course playing/watching soccer. While my older brother is following his dream as a Cardiology fellow at Emory University, I am continuing my journey and pursuing my passion as a surgical resident.
