Christopher Irobunda, MD, is a full time faculty member and an assistant professor of medicine at Columbia University College of Physicians and Surgeons and attending physician at NewYork-Presbyterian Hospital. He trained as a general and interventional cardiologist. Dr. Irobunda has been a full-time faculty since 2003. He obtained his MD/PhD in the Medical Scientist Training Program at the Albert Einstein College of Medicine in the Bronx, NY. His PhD was in Molecular Pharmacology specifically on the cyclic Adenosine MonoPhosphate/beta-adrenergic signal transduction system. He subsequently completed internship and residency in internal medicine at New York University Medical Center followed by his General and Interventional Cardiology Fellowship here at Columbia University Medical Center. After completion of his medical training and research study, he shifted his concentration to patient care and the education of aspiring young physicians.

Dr. Irobunda is ardently dedicated to uncompromised patient care and teaching. His primary focus is individualized patient care and patient advocacy. Given his training as a medical scientist, it is hardly surprising that he is a keen diagnostician. He has a penchant for complex cardiac issues and other medical problems that can sometimes mask or aggravate cardiac disease. His aptitude for unraveling these medical conundrums, have led to medical diagnoses for patients who have come to him for second and even third opinions. However, above all else, his true genius is his ability to relate to his patients with intelligence, curiosity, patience, compassion, and humor. His ability to waylay even the most apprehensive of patients with his aura of reassurance and understanding, has garnered him a continually growing medical practice. Again and again, individuals will refer family members and friends because of the empathy and level of care constantly provided. Indeed, his unceasing diligence has led him to become a physician member of Columbia University Medical Centers Patient Facilitated Services, an organization that is directed at patient satisfaction and outreach. Dr. Irobunda has also been the primary cardiologist for patients undergoing liver transpalnt evaluations at New York Presbyterian since 2004.

When not in his private practice, he takes great pleasure in helping train the new influx of physicians in the only ethical way to practice medicine—patient centered care. Dr. Irobunda has been a Supervisor and Attending Faculty for the Fundamentals of Clinical Medicine for First Year Medical Students at Columbia University College of Physicians and Surgeons since 2011, a program which endeavors to instill exceptional patient-doctor communication and trust. He encourages these future practitioners of medicine to listen to the patient and to learn to interpret and analyze the information that is being imported; to realize that the seemingly insignificant details sometimes lead to the culprit of an individual's illness. He has been a lecturer with International Postgraduate Organization for Knowledgetransfer, Research and Teaching Excellent Students (IPOKRaTES) in Europe. IPOKRaTES offers opportunities for physicians from a plethora of countries to observe and gain instruction regarding differing methods in patient care practices. Since the summer of 2012, Dr. Irobunda has become involved in New York Presbyterian Hospital's Lange Youth Program which seeks to prepare and enumerate the rigors of medical school for high school students.

Dr. Irobunda is active in numerous community outreach organizations-Abyssian Baptist Church (NY), JP Morgan Chase Employee Education Program, Riverside Church Seniors, and Sister to Sister: The Women's Heart Health Foundation, to name a few. He seeks to educate the public on cardiovascular issues and ways to make everyday life style modifications to help reduce these risks. In addition to being an interventional cardiologist who can perform angioplasties and stent placements, he emphasizes the prevention and treatment of heart disease through diet, exercise, and medical therapy.
