We create hope, together.
Great Minds brings people together through fun, diverse social experiences to support brain cancer research.
Over 700,000 Americans are currently living with a devastating brain tumor diagnosis.
The cure starts with research. Improving the quantity and quality of brain cancer research is the best path to finding the cure.
We’re a like-minded community that envisions a world free of brain cancer.
A world where human ingenuity and resolve triumph over disease.
A world without the consequences of brain cancer.
Our Story
Great Minds, formally known as Roll and Roll Over Brain Cancer, was created in 2011 by brain cancer survivor Mary Kay Fenlon, to celebrate the 10-year anniversary of her brain tumor surgery and cancer diagnosis. Great Minds now organizes and hosts fundraising events each year, and as of 2026, has raised over $200,000 for brain cancer research and patient care.
Great Minds events benefit the Lisa B. Landes Brain Cancer Fund, established for the purpose of brain cancer research, patient care, patient experience, and patient enhancement at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) in Columbus, Ohio.
Our Team
Jen House, President
After dealing with seizures for four years, Jen had brain surgery and was diagnosed with grade III anaplastic ependymoma in 2021. She joined Great Minds shortly after concluding her radiation treatment at the OSUCCC - James. As a fervent supporter of research to help find a cure for brain cancer, she shares her story to raise awareness and support.
Mary Kay Ryan Fenlon, Founder
Mary Kay, a brain cancer survivor herself, truly understands the need for critical research funding, as well as continually improving comprehensive patient care. The driving force since 2011, Mary Kay has been an integral part of annual events and volunteer recruitment.
Melanie DiFeo, Treasurer
Melanie was diagnosed with a low grade glioma after a successful brain surgery in 2016. She is passionate about supporting critical brain cancer research, learning about emerging technologies, and spreading hope among all those impacted by brain tumors.
Laurie Zinn, Secretary
In 2022, Laurie’s 17-year-old son was diagnosed with a low-grade brain tumor and successfully treated at the OSUCCC – James. That experience ignited her commitment to advancing brain cancer research. She joined Great Minds to honor her son and all survivors, and to help raise critical funds so families facing this diagnosis have more hope—and ultimately, a cure.
