From the program directors

Thank you for your interest in our program. We believe we have one of the best genitourinary fellowships in the country. The breadth of material and volumes in our practice provide an immersive setting for our fellows, not only to become competent in the handling of routine genitourinary cases but to develop expertise in uncommon and rare entities.

Our curriculum encompasses many hands-on experiences and allows the fellows to progress in responsibility and independence in the sign-out of genitourinary specimens. Our fellows participate in every aspect of every case, including preliminary assessment, selection and integration of ancillary studies, and consulting with other subspecialty experts if needed.

The consult service provides additional exposure to diagnostically challenging material and allows the fellow to participate in cases from the perspective of nationally recognized genitourinary experts. The close collaborations we have with other colleagues in anatomic pathology, molecular pathology, hematopathology, and molecular genetics are unique to our training.

Our core faculty are very engaged in education and research and have additional expertise in several other complementary subspecialties, including molecular, breast, renal, neuropathology, endocrine, and head and neck pathology. Our fellows are also involved in presenting at tumor boards and intradepartmental conferences and have the option to participate in several educational lectures and conferences available to the residency program.

Mayo Clinic is a unique workplace where the interests of the patient are at the center of all we do, which fosters deep collaboration and teamwork with our clinical colleagues.

Our faculty are committed to teaching and facilitating the growth of medical knowledge. Many of our faculty members have published and lectured extensively and are highly regarded in their fields.

Advisers and mentors

Fellows are assigned dedicated faculty mentors who can provide comprehensive educational advice and personal support. Trainees meet with their mentors periodically throughout the fellowship to review progress and career goals and ensure that their educational needs are being met. Mentors also serve as a contact point for introducing fellows and their families to Rochester, Minnesota, and the Mayo Clinic system.

Visiting professors

Many prominent professors visit Mayo Clinic each year. They present their work during lectures and participate in grand rounds and informal discussions with trainees. Fellows are encouraged to take full advantage of these educational opportunities.
