Dennis J. Ahnen, MD, FACG

Dr. Dennis Ahnen completed his Medical School Training at Wayne State University in Detroit Michigan and completed a Medical Residency and Chief Residency at Hutzel Hospital in Detroit before coming to the University of Colorado as a Fellow in Gastroenterology in 1977. After completing his Fellowship, he completed a Membrane Pathobiology Fellowship at Stanford University before coming back to join the faculty of the University of Colorado School of Medicine in 1982 where he is currently a Professor of Medicine.

Dr. Ahnen’s research interest is in understanding the process of colorectal cancer and its prevention. His laboratory has conducted both basic and clinical investigations related to this issue. At the basic level Dr. Ahnen’s laboratory has examined the biologic and biochemical mechanisms of the chemopreventive effects of the non-steroidal anti-inflammatory drugs (NSAIDs). Dr. Ahnen’s laboratory was one of the first to demonstrate that NSAIDs induce apoptotic cell death as well as cause cell cycle arrest and his laboratory showed that this effect could be induced by metabolites of NSAIDs that did not inhibit cyclooxygenases suggesting that there were other biochemical targets for these drugs, one of which is a subclass of cGMP phosphodiesterases and another is inhibition of EGF receptor signaling. Pam Rice PhD has been a co-investigator with Dr. Ahnen in the laboratory and is central to the basic science work.

Dr. Ahnen’s laboratory also is active in clinical and behavioral studies of colon cancer prevention. The clinical laboratory group has conducted trials of screening colonoscopy, stool DNA testing, and adenoma prevention trials with non-steroidal anti-inflammatory drugs, folate supplementation and calcium and is currently conducting adenoma prevention trials testing selenium, Vitamin D and Calcium and DFMO as chemopreventive agents. In collaboration with Drs Jan Lowery and Al Marcus, Dr. Ahnen conducts behavioral trials designed to improve colorectal cancer screening rates in high risk populations such as first degree relatives of patients with colorectal cancer. In collaboration with Dr. Jan Lowery, Dr. Ahnen directs the Colorado site for two Cancer Registries that identify families with clustering of colorectal or other cancers.

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 multispecialty group in the foothills of the Blueridge Mountains in Hickory, North Carolina. Three years into practice the other gastroenterologist who joined me separated from the multispecialty 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, of which I am in my second term. 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. Last year I was asked to chair the National Affairs Committee with the ACG which is an obvious are of great passion that I am enjoying at this time as well.

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.
