Meet Our Fellows

Why Mayo: I came to Mayo Clinic for residency because of the high-caliber training that it provides to its trainees, including residents and fellows. The OBGYN department prioritizes resident education and learning so that we can get the most out of our time here.  The residents and fellows work closely with each other and there is a sense of camaraderie rather than competition.  The teamwork and patient-centered medicine attributed to Mayo Clinic is real and she will be amazed how the people here are genuinely helpful and will go out of their way to care for their patients. You get to learn at the top-ranked hospital in the nation and the top-ranked gynecology department in the nation all while living in an affordable family-friendly place with an amazing commute.

Class of 2025

Si Won Lee, M.D., Ph.D.

Si Won Lee, M.D., Ph.D.

Hometown: Seoul, South Korea

Medical school: Ewha Women’s University, College of Medicine, Seoul, South Korea

Residency: Mount Sinai Medical Center, Miami Beach, Florida

Things I do in my free time: Figure skating, golfing, learning new sports, playing piano, listening to music, watching K-dramas, cooking, baking, and drinking wine with my friends and family.

Why Mayo: When I was applying for a fellowship, the most important factor that I considered was to be in a place where I can see myself in the future — happy and accomplished. I believe the Reproductive Endocrinology and Infertility division at Mayo Clinic will provide me with diverse and challenging cases from all over the world and I love that Mayo provides balanced training between clinic, research, and education and incredible mentorship. During the interview, I was thrilled to learn that Mayo offers high-volume complex reproductive surgery as well as in vitro fertilization (IVF) training which will make me a well-rounded reproductive endocrinologist. I could feel that fellows are treated like family and are very well supported. I'm very excited and feel grateful to start my new adventure at Mayo Clinic's Reproductive Endocrinology and Infertility Fellowship in Rochester, Minnesota!

Class of 2026

Cyra Cottrell, M.D.

Cyra Cottrell, M.D.

Hometown: Pittsburgh, PA

Medical school: University of Florida College of Medicine, Gainsville, FL

Residency: Morehouse School of Medicine, Atlanta, GA

Things I do in my free time: As a Pittsburgh native and a former Division 1 athlete, I grew up loving to play and watch sports, which continues today (Go Steelers, Go Gators!) I’m a big fan of water sports, fishing, and being outdoors in general. I love traveling and taking my son and dog on adventures. I enjoy live music and singing (currently working on learning to play the guitar.) My Italian heritage makes me passionate about good food and wine!

Why Mayo: I was aware of the outstanding reputation Mayo Clinic has in the healthcare field, but I didn’t realize just how special Mayo Clinic was until my interview day. The fellows and staff were friendly, inviting, and easy to talk to. You would never guess by how humble they are that they're a part of the best hospital in the country. During my interview day, I kept asking myself, “Could this place get any better?” It was an effortless fit. I’ve always been driven by a passion to serve my patients, and Mayo has all the resources to support me to be the most competent, educated, and empathetic provider possible. Mayo’s mission identically parallels my own, which made selecting Mayo Clinic for fellowship a very easy decision.
