Giving Circles
As a public charity, the impact made through ROI programs are only possible because of the generosity of people who believe in the power of radiation therapy.
ROI celebrates those who give generously by recognizing their support as a member of a unique giving circle. Collectively, these donors bring together critical resources that are helping to accelerate the boldest and most innovative ideas to help people live longer, healthier lives.
Every member of a ROI giving circle receives information and experiences to see the impact they are making through the following benefits:
- Invitation to a special recognition event during the ASTRO Annual Meeting
- VIP seating during a keynote session at the ASTRO Annual Meeting
- Recognition throughout the year online and in-print
The ROI President's Circle celebrates donors who give $1,500 or more per year.
Residents who hold an ASTRO Member-In-Training membership and non-physician clinical health care specialists who hold an ASTRO Associate membership are invited to join the ROI President's Circle with an annual gift of $100 or more (visit the ASTRO Member Categories for additional information).

An easy and convenient way to give to the ROI is through monthly giving. You can set up your gift to be paid each month. Become a member of the Sustainers' Circle by making a monthly gift. If you are interested in becoming a member of the President's Circle, you can make that leadership gift with a monthly gift of $125. Monthly giving provides a continuous source of revenue on which that the ROI can rely.
Monthly donors are commenting:
“I have been giving intermittently to the ROI in small amounts for several years. Recently, I learned I could set up my monthly donations. It’s convenient and low maintenance. I prefer this method of giving so much more.”
“I wanted to make a contribution that matters and found that by making a monthly gift, it was easy to increase my giving.”
“I was always wondering if I had made my annual gift or not. This way, I could just set up the monthly gift and I didn’t need to think about it. I would know it is covered and it gives the ROI a source of revenue it can depend on.”
"The field of radiation oncology has been very good to me. I love the work that I do in being able to take care of patients. And our field is not stagnant. It's constantly evolving for the better. These evolutions come through research. Unfortunately, research funding is more and more difficult to come by. This is why the Radiation Oncology Institute is critical to the future of our field. And this is why I support the ROI. We are all busy. I firmly believe that most radiation oncologists believe in the mission and value of the ROI. But they (we) just get busy with day-to-day life and forget to make a donation. I am guilty of this as well. This is why I appreciate the monthly contribution option. This process took me 2 minutes to set up online. I make a modest contribution each month, but it adds up. I do not miss the money. And now I know that I am supporting the ROI and more specifically the researchers who are going to continue to push our field forward."
We gratefully acknowledge the following individuals for their contribution to the ROI through a planned gift:
Theodore Lawrence, MD, PhD, FASTRO
Dr. Colleen and Mr. Patrick Lawton
Christopher M. Rose, MD, FASTRO
