From the chief residents

Three chief residents for Pediatric and Adolescent Medicine Fellowship MN Welcome to Mayo Clinic—home of excellent patient care, exceptional educators, and lasting friendships. We are thrilled that you are considering the Mayo Clinic Pediatrics Residency as the next step of your medical career. It has been our privilege to train at Mayo, and we are convinced that the combination of Mayo’s abundant resources, outstanding faculty and allied health professionals, and patient diversity would be of great benefit to you as well.

Our residents choose Mayo Clinic for many reasons. For some, it is the incredible breadth of elective experiences available and the 1-on-1 time with faculty. For others, it is the low-key living that Minnesota affords. One thing we have all appreciated is our program’s engaged leadership and administrative teams. Dr. Pittock and our Associate Program Directors are responsive to resident feedback about improving our program and work hard to support each resident in pursuing their unique educational goals during residency.

As chief residents, it is our commitment to help you find a training program in which you and your patients thrive. If you’re intellectually curious, hardworking, and love caring for children, Mayo Clinic would be that perfect fit! We look forward to meeting you during interviews, and we welcome any questions you might have along the way.

Warmly,
Ben Ashby M.D., M.T.S., Tomini Fashina, M.B., Ch.B., M.P.H., Justin McKone M.D., M.P.H

Our neighbors are friendly, the interconnected park system around town is wonderful for spending time outside, and we’ve both enjoyed our work environment (my wife teaches at Kellogg Middle School)!

I'll try anything new at least once — this year I want to learn to sail and scuba dive in the summer and ski and snowboard in the winter. I also love baking doughnuts and cupcakes and traveling to every nook and cranny of this world. And as a classic resident, I also enjoy watching inaccurate but entertaining medical dramas in my free time.
