GME Internal Medicine Residents

Chief's Welcome

Hello and Welcome to Mercy!

I am overjoyed to be the Internal Medicine Chief Resident for the 2026-2027 Academic year! This new role is the first chapter of my career as an independent physician and I am grateful to have you all be part of it.

I am originally from the East Coast, spending my formative years in the same town that my parents immigrated to from Poland. As a first-generation Polish American, my parents were a continuous example of the pursuit of the "American Dream," yet my heritage continued as a deep part of my identity. They encouraged me that all goals were worth the pursuit and supported me every step of the way. To this day, that support continues as we celebrate the culmination of my training and the start of being an attending physician. 

A career in medicine was always meant for me. I completed my undergraduate degree in Biochemistry at Seton Hall University. Upon graduation, I held roles in the pharmaceutical industry moving across various manufacturing sites in the United States but ultimately, I realized that I should be bedside with the people these medications and vaccines were reaching. I completed my medical training at St. George's University School of Medicine matching Internal Medicine at Mercy Hospital. The Midwest was an unofficial second home and I formally set roots here for training. When I first started here as an intern, one of the things that struck me the most was how the department embraced the decor of "DoM." To them, I realize it simply stood for "Department of Medicine," but for me "DoM" in Polish, translated to "home," and home it became.

I have very much cherished my last three years at Mercy. Through the unconditional support of the department - leadership, supervising physicians and administrators - the experiences in residency have made me both the doctor and person I am today. But it is my patients that I am most appreciative of - the immediate entrustment they have given - what a privilege to be part of their lives.

I hope that as you learn more about our program you become excited to! Mercy Hospital (St. Louis) has a rich history in medical education as one of the oldest community hospitals in the nation for internal medicine training. The trainee experience is filled with a variety of clinical exposures like that of a university program with a level of individualized learning only possible in a community setting. Our Graduate Medical Education is comprised of various other training programs and continues to grow each year.

I am forever thankful for this training, feel well-prepared to move into independent practice and look forward to witnessing the continued development of many quality physicians who will graduate from this program. And for you, if it becomes the right fit, I hope you find "home" here too.
