Caroll D. Koscheski, MD, FACG
After finishing undergraduate work at the University of Oklahoma I worked in the medical field as a Medical Technician for a few years before making the decision to apply for medical school. I then attended Louisiana State University Medical School in New Orleans where I not only completed my medical school training but stayed on through my residency and GI fellowship. The thought of private practice had always appealed to me and I began practice in a multi-specialty group in the foothills of the Blueridge Mountains in Hickory, North Carolina. Three years into practice the other gastroenterologists who joined me separated from the multi-specialty group and formed our own independent practice in gastroenterology here in Hickory. The practice has thrived as we have worked through the many decision points involved in business management including contract negotiations with insurance companies, office management and the always difficult decision of when to add a new associate. We eventually added an endoscopy ASC to our unit which is entirely owned by us as well. We currently are a practice of 8 physicians.With our sons moving on toward college and careers of their own, I have finally allowed more time to devote to my involvement in the ACG. This has included being elected North Carolina Governor. I have also been very involved with the political aspect of medicine, especially at the state and federal level and am serving on several committees by request of the North Carolina Medical Society. I was a past chair of the ACG National Affairs Committee, which is an obvious area of great passion that I have enjoyed.

Ronald D. Szyjkowski, MD, FACG
As a student, the physiology of achalasia fascinated me and sparked my interest in gastrointestinal diseases and having rotated on GI doing my first colonoscopy with one of our surgical staff at Loyola in Chicago, I was hooked. It seemed to me that gastroenterology was a perfect fit for a Med-Peds graduate. After finishing my training in El Paso at William Beaumont Army Medical Center, I pursued fellowship training and was lucky enough to receive great training and exposure to both adult and pediatric patients and fished my fellowship at Brooke Army Medical Center. After completing my 14 years of Army service, my family and I relocated to our home area of Upstate New York where I presently am lucky enough to serve as Training Director and Division Chair of gastroenterology. At each stop along this journey I remained very active in medical education, holding many different positions, but throughout, my passion lies in diseases of the foregut and esophagus with emphasis on the care and treatment of patients with Barrett’s and achalasia. Procedurally, I enjoy diagnostic and therapeutic EUS as well as endoluminal therapy of Barrett’s and adenocarcinoma.
