“Dear Endocrinology Fellowship Applicants, on behalf of the program leadership of the endocrinology fellowship program of the University of Miami, Jackson Memorial Hospital, and the Miami VA Healthcare System, we would like to extend our heartfelt congratulations to you for successfully matching for an endocrinology fellowship program. This marks the beginning of a challenging yet rewarding chapter in your medical career. The training years will undoubtedly be filled with long hours, complex cases, and a wealth of knowledge to absorb.

  1. Embrace the challenges that come your way. While training years feel like a marathon, they go by faster that you can imagine. See as many patients as you can, engage in meaningful research, and take advantage of the faculty and resources at your programs.
  2. Keep an open mind. When you receive feedback, take a moment to reflect and incorporate changes to yourself and learning habits.
  3. Look around you and help your co-fellows. These are your colleagues with whom you will engage with throughout your careers. The training years can often feel humbling and daunting, but you have chosen one of the most challenging, and rewarding careers in the world. Before you know it, you will be looking back at these years with a sense of pride and accomplishment.

As you embark on this journey, carry with you the excitement of this moment. Stay curious, stay resilient, and remember that you are being handed an opportunity to impact the lives of patients and the broader medical community. Congratulations once again, and we look forward to witnessing your growth and success as a future leader in endocrinology.

To those of you that did not match, do not lose hope. This setback does not define your capabilities or potential. Take this time to reevaluate your individual situation, assess your goals, and consider the next best steps in your career. Unforeseen circumstances can sometimes lead to unexpected opportunities, and a different path may unveil itself.” Wishing you much success!

— Rokshana R. Thanadar, MD


“Welcome to the endocrinology family! We are all excited to meet you, teach you, learn from you, and work with you as future colleagues. You will learn endocrinology in your fellowship but your internal medicine knowledge will be at its peak at the end of residency. Therefore, take advantage of the end of residency to consolidate your internal medicine knowledge and prepare for your internal medicine exams. The beginning of fellowship will be busy with a steep learning curve so the more you have prepared for the board exam already, the more you can focus on making the transition successful.” 

— Ole-Petter R. Hamnvik, MB BCh BAO, MMSc, MRCPI, Program Director, Endocrinology Fellowship, Brigham and Women’s Hospital, Associate Professor of Medicine, Harvard Medical School, and Education Editor, NEJM Group


“Congratulations! In July you will be starting a new chapter in your career. There will be a steep learning curve in the first few months of fellowship. We all go through this. Enjoy your last stage in training. I would advise you to find good mentors (it can be one or more one).  In my career my mentors have been my biggest advisors and have helped me achieve my goals. Good luck!”

— Gisella Carranza Leon, MD, Associate Professor of Medicine Medical Director, Vanderbilt Eskind Diabetes Clinic Division of Endocrinology, Diabetes and Metabolism, Vanderbilt University Medical Center
