Laura L Onderko

After completing my internship in Internal Medicine-Pediatrics and residency training at Maine Medical Center, it was an easy decision to stay at Maine Medical Center for my adult cardiovascular disease training, serving as chief fellow in my final year. I am excited to be staying in Maine to practice as a clinical cardiologist with special interests in cardiac imaging, including cardiac CT, echocardiography and nuclear imaging and cardio-oncology, which focuses on the intersection between cardiology and oncology.

Outside of work, my interests include running, hiking and exploring Maine with my husband and two daughters. I look forward to practicing cardiology here in Maine where I have trained, and being able to provide the best care possible to Maine’s population.
