Why did you choose Mayo Clinic for your dermatology training?

I chose Mayo Clinic for dermatology residency because of its high caliber of medical training, ample resources for resident education, and supportive community. Our program provides experience in all areas of dermatology, including dermatopathology, pediatric dermatology, cosmetic dermatology, and dermatologic surgery, while providing the opportunity to learn directly from leading experts in the field. As a major referral center, we see a wide variety of clinical cases from common dermatologic conditions to rare diseases. This breadth of clinical experience builds confidence to care for any patient after graduation. What also sets Mayo apart is the incredible support for residents with three dedicated program coordinators, generous conference funding, protected didactics time, and a strong emphasis on graduated autonomy. Lastly, and most importantly, all members of the care team genuinely enjoy working together to provide the best care for our patients.

What are some of your favorite things about living in Rochester?

My favorite part about living in Rochester is how beautiful and green it is. I grew up in the desert, so I was amazed by the lush green summers and the vibrant fall colors. I love spending time outdoors, exploring new trails or walking around the many lakes with our dogs. Rochester is a mid-sized city but has everything you need from coffee shops to farmers market, and there are so many trails and parks to explore.

How is Mayo Clinic helping you reach your career goals? 

I am interested in pediatric dermatology and working in academic medicine. Mayo Clinic is fortunate to have five board-certified pediatric dermatologists who are not only incredibly knowledgeable but also very supportive. I have benefited from their mentorship as well as been able to work on pediatric dermatology research projects. Additionally, Mayo’s strong academic environment has allowed me to engage in teaching and mentoring medical students, which aligns closely with my long-term goal of working in an academic setting.

Why did you choose Mayo Clinic for your dermatology training?

I chose Mayo Clinic for the culture. It's rare to find a mission-oriented organization where everyone at all levels of roles and responsibilities feels the same commitment to the needs of the patient. This creates a shared sense of pride in our work and the care we provide. It's also a true privilege to learn from some of the most brilliant minds in our field and train in a department that incorporates the latest advancements in research and technology.

How is Mayo Clinic helping you reach your career goals? 

Faculty in all subspecialties of dermatology here are equally welcoming and eager to nurture your passion for their respective fields. Thanks to our large department, there is no shortage of mentors for career advice, research, and networking. As far as my interests in dermatologic surgery, I feel fortunate to be able to learn from several different surgeons who are all world-class, approachable, and kind. Opportunities for research are endless, and Mayo Clinic's generous trip policy allows me to attend most of the important meetings in the field. Teaching is ingrained in our program as residents transition into more of a teaching role in their final year, leading sessions for their junior residents on pathology, surgery, and medical dermatology.

What is it like to live in Rochester?

Rochester is a rapidly growing city that has been able to retain a quiet and peaceful pace of life. Every year, I am pleasantly surprised to find new restaurants in town offering different cuisines. Throughout the year, there are events such as the County Fair, Thursdays Downtown, and Social Ice that bring the local community together.

Why did you choose Mayo Clinic for your dermatology training?

I chose Mayo Clinic Dermatology because of the excellence in dermatologic training and the culture of medicine at this program. At Mayo Clinic, the needs of the patient are always the priority, and as trainees we learn to optimize patient care through resident education, mentorship, and a culture of safety. Additionally, I was searching for a comprehensive dermatology program that offers a wide range of learning experiences in complex medical care, surgical practice, pathology, and research.

What is the work/life balance like in this program?

The work life balance at Mayo Clinic Dermatology is truly excellent. While residents are encouraged to become involved in education, leadership, research, and other opportunities to advance their learning and career development, we pursue these interests at our own pace. I was privileged to become a father during my first year of training and was able to find a fulfilling balance between home and work responsibilities.

What is one of your favorite things about being a Mayo Clinic Dermatology resident?

My favorite thing(s) about being a Dermatology resident at Mayo Clinic are my incredible co-residents. The support, friendship, and collaboration between residents makes this program particularly unique and enjoyable. It is a pleasure to train alongside such kind, intelligent, and passionate physicians.

Why did you choose Mayo Clinic for your dermatology training?

Mayo Clinic was my top choice because it offers everything I was looking for in a residency: outstanding clinical training, exceptional mentorship, and a culture that encourages curiosity, collaboration, and lifelong learning. I was especially drawn to Mayo's patient-first philosophy, the longstanding tradition of supporting and investing in trainees and alumni, and the opportunity to learn from leaders across every area of dermatology. I also appreciated the program's emphasis on graduated autonomy, which allows residents to build confidence and independence while always feeling supported. As someone who moved far from home to pursue training, it has meant a great deal to be part of a community that genuinely welcomes people from diverse cultures and backgrounds. I have been especially inspired by the incredible women leaders in our program, whose commitment to mentoring, supporting, and empowering the next generation of women in dermatology is truly remarkable. From my very first interactions, it was clear that Mayo is a place where people genuinely invest in one another's growth, and that has made it an incredible environment to train in.

Is there anything that surprised you about living in Rochester?

Before moving here, I was a little worried about the long winters, but the city, and Mayo's connected campus, made adapting incredibly easy. Instead of dreading winter, I found myself embracing it. Living here has felt like being in a winter wonderland, with opportunities to explore cross-country ski trails, see people ice fishing on the lake next to my apartment, and even catch the occasional breathtaking display of the Northern Lights. I even got used to continuing my outdoor runs throughout the winter, where spotting deer along the trails still feels a little magical. Rochester offers the perfect balance of a close-knit community with easy access to the amenities of larger cities, while giving you the chance to experience the warmth and kindness that "Minnesota Nice" is known for. It has truly become a place I enjoy calling home and a wonderful community to live in, both during residency and beyond.

What has been one of your favorite experiences in the residency program or with your fellow trainees?

One of my favorite parts of residency has been the friendships I've built with my fellow residents. I still smile thinking about painting our faces and dressing up for one of my co-resident's child's first trick-or-treat, learning how to cook a traditional Norwegian meal from the father of one of my closest co-residents after they generously hosted my partner and me for Thanksgiving so we wouldn't feel so far from home, learning to mountain bike with another co-resident's wife, painting Christmas ornaments together, making our Monday Lagree classes a tradition, and spending Saturday mornings swimming before enjoying our favorite protein smoothies and a relaxing sauna. It is these shared moments and the unwavering support we have for one another every day that have made Mayo feel like a second family, and created friendships I know will last well beyond residency.
