Why did you choose to specialize in cardiothoracic imaging? Because I liked the dynamic/functional aspects of cardiothoracic imaging - it pairs well together with my nuclear medicine training.
What attracted you to Mayo Clinic for fellowship training? I was here for residency and have grown to love working with the attendings who are excellent teachers, and our imaging quality and technicians are second to none.
What makes the cardiothoracic imaging program unique? The program has a lot of exposure to congenital heart and transplant (heart and lung) cases. It also has great attendings who are good mentors and teachers.
What do you love about the program? I love that if I have a question on a study, even if it's outside of the chest, I can walk over to that division and ask their opinion. There's no judgement for questions here.
What is it like for you to live in Jacksonville? Jacksonville is not too big of a city that it feels too crowded and not too small that you don't have anything to do. It's right in the middle. I like that I can still go to the beach or other nature areas and am not landlocked in a concrete jungle.
What are your favorite things to do in Jacksonville? My favorite things to do are vegan baking and cooking, beachcombing, playing videogames, and spending time with my friends and cats.
