Our residency draws trainees from across the U.S. and around the world. While all our trainees have a love of learning and a compassionate approach to patient care, they come from diverse backgrounds, family status, and professional and personal interests.

Why did you choose Mayo Clinic?

I chose Mayo Clinic for its reputation in clinical excellence and research. The supportive training environment and emphasis on education really stood out to me. The subspecialty structure, strong case diversity, and access to rare and complex cases were major draws. I also appreciate the balance of autonomy and mentorship throughout training and value the strong focus on teaching and genuine investment the faculty have in residents' growth and success.

What stood out to you about this program?

I had the opportunity to complete my medical school training at Mayo Clinic, and had a wonderful experience. The staff and faculty were incredibly influential in my decision to pursue pathology, and I wanted to continue working with them in residency. 

There is an incredible emphasis on mentorship and training at Mayo Clinic. The faculty and staff are excited to teach, and help provide unique opportunities to grow and learn. It felt as though for any interest I could think of, there was at least one person that shared that interest, and was willing to help me pursue it. Not only that, but there seemed to be a vested interest in creating a positive, supportive environment for education and research.

What stood out to you about this program?

It's a really well-rounded training program and you get excellent exposure to both AP and CP.  Having access to Mayo Clinic Laboratories means you get to see interesting tests coming in from across the world as well as consult cases from outside Mayo.  Also, I felt that I would have access to a lot of resources across 3 campuses.  There's always someone doing research on something new and cutting-edge here, so I knew that whatever I wanted to do with my career as a pathologist, there would be opportunities to get involved in something exciting.

What do you like about living in Rochester, MN?

I love Rochester because it is a fun, safe, and affordable place to live, work, and play. It offers a myriad of recreational activities and dining options, along with a strong housing market that gives me and my family health and security for our future. Not to mention, the traffic is very manageable compared to my previous location, so that is a huge plus!

Why did you choose Mayo Clinic?

I chose Mayo Clinic because it offers exceptional training, upholds the highest standards of diagnostic practice, and leads the way in research and innovation. I was especially drawn to how much the program invests in its residents—not just in education, but in their overall growth. It offers a supportive and intellectually stimulating environment where I know I will feel comfortable asking questions and inspired to grow. The sense of community and the resources available here make it a place where I can see myself thriving both professionally and personally.

What stood out to you about this program?

What stood out to me about this program was how down to earth and relatable everyone was on my interview day. Despite Mayo attracting pathologists who are well-renowned in the field, everyone who I met with was kind, interested in my life outside of work, and genuinely engaged in teaching. Other aspects that have stood out to me since starting are the dedicated education specialists for our rotations and the well-established digital pathology program.

Why did you chose Mayo Clinic?

Mayo Clinic is known as one of the top hospitals, especially for its incredible patient care—which is exactly what I aim for in my medical career. Additionally, I kept hearing 'the Mayo way or the other way' during shadowing, so I had to check it out for myself. What stood out to me was the unparalleled exposure to complex and rare cases, the strong emphasis on resident education, and the welcoming, collaborative vibe I got during the interview.

Why did you choose Mayo Clinic?

I chose Mayo Clinic not only for its unparalleled resources, but also because of the Rochester area and my interview experience. I was pleasantly surprised to find how humble everyone was despite being at such a renowned institution. The residents also seemed genuinely happy and had no major complaints, not even the standard grossing time complaints you hear about everywhere else.
