Why I chose this residency program: I chose USF/Moffitt Cancer Center because of the relationship between the residents and the faculty. The staff prioritizes the learning experience of residents along with providing significant guidance and support in resident-led research. Furthermore, the combination of Moffitt’s high clinical volume and resident autonomy offers superb clinical training for our future careers.

Jeffrey Peacock, MDJeffrey Peacock, MD
Why I chose this residency program: My relationship with Moffitt began 10 years ago as an undergraduate in the SPARK Research Program. At Moffitt, I was exposed to cutting-edge research combined with compassionate patient care. That, along with my work in breast cancer research with a physician-scientist, shaped my future as a physician. I knew 10 years later as an MS4 student that I wanted to do my away rotations in radiation oncology at Moffitt. I knew it was the perfect place to train as a radiation oncologist. The educational opportunities here are plentiful and readily available. The Moffitt residency program prioritizes education above all else.  The environment is supportive and friendly among residents and faculty alike. Moffitt has enabled me to realize my professional goals. Every day that I walk through the Moffitt entrance as a radiation oncologist in training, I could not be happier with my decision.

Russell Palm, MD
Russell PalmRussell Palm was born in Columbus, Ohio, and grew up in West Virginia.  He attended The College of Wooster as an undergraduate while majoring in neuroscience and then performed research in Alzheimer’s disease at Case Western Reserve University in Cleveland, Ohio in the laboratory of Gemma Casadesus. He completed medical school at the University of Toledo College of Medicine and subsequently a transitional year internship in internal medicine at Riverside Methodist Hospital in Columbus, Ohio. 

Why I chose this residency program: When I was evaluating residency programs, I was encouraged by Moffitt due to their excellent reputation as well as the strong patient volume that comes to a NCI comprehensive cancer center. The work environment is collegial and the quality of life is superb in Florida.  Additionally, there are ample resources and support available to pursue clinical and translational research. In my free time I enjoy exploring the Tampa/St. Pete area including the surrounding beaches, trying new restaurants and breweries, and going to football/hockey games and live concerts.

Austin Sim, MD, JD
Austin SimAustin Sim is originally from Bel Air, Maryland. He attended Washington University in St. Louis where he double majored in Biochemistry and Finance. He completed medical school and law school as the first student in the joint MD/JD program at the University of Virginia before finishing his internship in Internal Medicine at Virginia Commonwealth University. Outside of medicine, he has interests in implementation/legislation of health policy, the science of cooking/baking, and making craft cocktails. 

Why I chose this residency program: I chose Moffitt for residency because of the depth and breadth of opportunities paired with excellent clinical training. As one of the highest volume cancer centers in the country, Moffitt provides rigorous training, but without being overwhelming due to excellent support structures that prioritize education. Additionally, with initiatives like Total Cancer Care, Moffitt offers a wealth of research opportunities. Lastly but no less importantly, the collegiality and camaraderie both within and beyond the department make Moffitt a fun and warm place to train.

Anupam Rishi

Anupam Rishi, MBBS
Anupam was born and raised in India. He attended Calcutta University for medical school and later pursued Residency in Radiation Oncology from Post Graduate Institute of Medical Education and Research, Chandigarh, and Senior Residency form Tata Memorial Hospital, Mumbai. During residency he initiated and completed Randomized Study in locally advanced oropharyngeal cancers which received an ASTRO abstract award. Anupam completed a Surgical Intern year at USF before starting his residency at Moffitt. Outside work, Anupam, a former college-level Cricket player in India, loves to travel with his wife Papri (a current USF Ob/Gyn resident), and cook recreationally. He has a new-found interest in fishing.

Why I chose this residency program: I chose Moffitt/USF for my residency training as Moffitt offers a very strong research infrastructure, large volume of patients and collaborative environment for both clinical or translational research. Most importantly, the Radiation Oncology department has very cordial environment, and the faculty are very invested in resident well-being and mentorship. In addition, no one can deny beautiful life in Tampa, many vacation-worthy nearby places and beach in Florida. Love the sunshine state!

Ammoren DohmAmmoren Dohm, MD
Ammoren is a native of rural Minnesota and the oldest of five siblings. He attended Brigham Young University where he majored in neuroscience and married his lovely wife. Together they moved to North Carolina where Ammoren attended medical school at Wake Forest and his wife completed her MHA. They recently purchased a home in Wesley Chapel and are looking forward to their time in Florida. In their free time, they enjoy traveling, hiking, beach days, tennis, pickleball, and dinner with family and friends.

Why I chose this residency program: During the interview process, I was impressed with Moffitt leadership's clear vision and execution strategy for the Radiation Oncology Department. I wanted optimal training opportunities, and I knew Moffitt could deliver because it has been nationally ranked by U.S. News & World Report since 1999, is consistently ranked in the Top 10, is one of only 51 National Cancer Institute-designated Comprehensive Cancer Centers nationwide, and is a research powerhouse with over 450 clinical trials. I found the culture at Moffitt to be ideal for me: warm, encouraging, and ambitious. Moffitt is also geographically appealing as Tampa is one of the country’s top vacation and retirement destinations.

Casey LiveringhouseCasey Liveringhouse, MD
Casey Liveringhouse grew up in Plymouth, Minnesota. He attended Luther College in Decorah, Iowa, where he majored in biology. He completed medical school and his internship in internal medicine at the University of South Florida. In his free time, Casey enjoys fishing, golfing, and spending time with his son, wife, and dogs.

Why I chose this residency program: I chose to do my residency at Moffitt Cancer Center because of the collegial atmosphere and stellar reputation, both clinically and in research. As one of the NCCN Member Institutions, Moffitt combines high clinical volume with exposure to rare cancers, which provides excellent clinical training. Resources for research are abundant, with an emphasis on developing strategies for the personalization of radiation therapy, which will be increasingly important as the field of oncology evolves. Most importantly, the camaraderie between residents and faculty fosters a supportive culture where I felt like I fit in very well.

Maria SandovalMaria Sandoval, MD
Maria Luisa (Mari) was born and raised in Quito, Ecuador and came to the US at age 18 for college. She attended Clark University in Worcester, MA then pursued a Masters in Physiology at Case Western Reserve University in Cleveland, OH where she completed her thesis in breast cancer stem cell markers and their role in response to treatment. She then attended New York Medical College for medical school and completed her intern year in medicine at the University of South Florida. In her free time, she enjoys boating with her husband and dog, traveling, drawing cartoons and organizing get-togethers for friends and family.  

Why I chose Moffitt

I chose to do my residency at Moffitt Cancer Center because it really encompassed all the features that I felt were essential in a program. One of the many strengths of this program was the genuinely warm and collegial atmosphere not just between residents but between attendings and residents. At Moffitt Cancer Center I have found that each attending and staff member in our department is truly committed to resident education. Additionally, as a high-volume cancer center and the only NCI-designated Comprehensive Cancer Center based in Florida, it provides an extensive breadth of opportunities for clinical training as well as abundant research opportunities. Finally, Tampa is a great place to live with many exciting indoor and outdoor activities.
