Executive Director Message


As we navigate the ever-changing landscape of COVID-19, your health and safety remain our top priority. We are continuing radiation therapy for our patients, including proton therapy, IMRT and SBRT, with extra measures in place to ensure your well-being.

We are in regular contact with public health officials and University of Florida Health experts on the latest information and guidance from the Centers for Disease Control and Prevention for reducing the risk of infection. It is our goal to share information and changes that we make as conditions develop and we adapt to protect patients and staff.

As always, I am grateful for the hard work and commitment our team has shown in protecting not only themselves and their families, but their patients and coworkers as well. I appreciate everyone’s cooperation as we all work together to “flatten the curve” and minimize the threat posed by COVID-19.

Thank you and stay safe.

Steps to Protect Your Family

Protecting Yourself and Your Loved Ones

Now, more than ever, it is important to protect your health and safety, and that of your loved ones. Outside of your visits to UF Health Proton Therapy Institute, there are steps you can take to help prevent the spread of COVID-19. Here’s how:

Wash Your Hands

Wash with soap and water for at least 20 seconds, especially after using the bathroom, sneezing, coughing or being in a public space.

Don’t Touch Your Face

Especially your nose, mouth and eyes. Cover coughs and sneezes with a tissue whenever possible, or your elbow, if necessary. Wash your hands immediately after.

Practice Social Distancing

Avoid crowds and close contact with people who are sick, keeping a distance of about 6 feet.


Stock up on supplies like over-the-counter medications, prescription medications, household items and groceries. Patients: Determine who can provide you with care should your caretaker get sick.

Sanitize Your Space

Clean and disinfect frequently touched surfaces in your home and car, and avoid touching high-touch surfaces in public places. Use a tissue or sleeve to cover your finger if you have to touch something.

Executive Director Message


Every New Year brings with it new ideas, new challenges and new promises. As we stand at the very beginning of a new decade, it is appropriate for us to look back at the progress made and our goals for the future.

As a pioneer in proton therapy, we have been and will continue to be at the forefront of new technology, advancements in research and life-saving clinical trials. We’ve treated over 8,500 proton patients, including more than 1,800 pediatric patients. In fact, over the past decade, we have more experience in pediatric proton therapy than anywhere else in the country and remain in the top five proton therapy centers worldwide for number of patients treated.  

With the start of patient treatments in our compact proton therapy gantry, Proteus®ONE, I’m encouraged to know that in 2020 and beyond, we will be able to treat more patients and additional types of cancer.

Our ongoing resolution and promise to you is that we will continue to help patients and future generations become cancer-free with a better quality of life.

Dr. Nancy P. Mendenhall Named UF Health Cancer Center’s 2019 High-Writer

Nancy P. Mendenhall, MD, and Jonathan D. Licht, MD, director of the UF Health Cancer Center

Congratulations to UF Health Proton Therapy Institute medical director, Nancy P. Mendenhall, MD, for receiving the UF Health Cancer Center’s 2019 High-Writer Award. The award recognizes Dr. Mendenhall’s leadership in research and cutting-edge care for her role as the lead investigator of the highest enrolling cancer-relevant clinical trials within the UF Health medical system.

As medical director, Dr. Mendenhall oversees the research department, including several clinical trials to treat more than 20 types of cancer. She and her team of clinical researchers have published over 150 articles in medical journals that report on patient outcomes, treatment techniques and efficacy of proton therapy.

Dr. Mendenhall is currently lead investigator on three clinical trials – an outcome tracking project, a trial investigating quality of life and side effects from proton therapy vs. IMRT for prostate cancer, and a prospective study comparing outcomes of proton and photon radiation in prostate cancer.

Santa Joe Delivers Donation for Children

Santa made an un-seasonal stop at the UF Health Proton Therapy Institute this month to spread more Christmas cheer to last throughout the year. Inspired by the children undergoing cancer treatment and his late brother, the “original” Santa in the family, proton alum Joe McGee works throughout the Holiday season as a professional Santa in the Atlanta area. Joe generously puts aside the proceeds he earns as Santa Joe and has returned to the Institute every January since 2014 to deliver a donation for the Children’s Fund.

This year, Joe mentioned that people have caught on to his mission and have donated above and beyond to benefit what he has named, “The Santa David Children’s Fund,” in honor of his brother. The funds he and his wife, Dawn, have shared over the last five years have directly impacted hundreds of children and their families by supporting various programs, child life staff and activities that aim to make treatment easier for even the youngest of children and allow them to enjoy being kids.

Santa Joe also makes an appearance every December at the Institute to hear the children’s Christmas wishes and deliver presents. 

“If I can bring joy to one precious little one, then it’s all worth it,” said Joe.

Current patients created an original painting to gift Santa Joe for his generosity, time and talent. You can book a Santa Joe appearance in the Atlanta area by contacting him at or email at

Research Shows Benefits of Protons

How proton therapy works

New research shows patients receiving simultaneous chemotherapy and radiation had fewer hospitalizations when they received proton therapy compared to conventional X-ray radiation therapy. What’s more, patients in the study had similar cure rates meaning that proton therapy was found to be as effective as conventional radiation with less costly side effects.

The researchers studied almost 1,500 patients with lung, brain, head and neck, gastrointestinal and gynecological cancers. Even though the patients receiving proton therapy were significantly older, they experienced two-thirds less adverse events associated with hospitalizations during the first 90-days of treatment. Proton patients were also more likely to be able to carry on work-related activities during and after their treatments.

The results of this study are significant because they support the value of proton therapy by demonstrating an improvement in quality of life and outcomes for cancer patients while providing value-based care for Medicare, Medicaid and private insurers.

Executive Director Message


We are capping off the decade with a commencement – the start of patient treatments in our compact proton therapy gantry, Proteus®ONE. This singular event is the culmination of three years of planning, constructing, installing and commissioning. It has been made possible through the efforts of a large team of highly trained men and women from many organizations. I’d like to acknowledge, thank, and congratulate all who were involved in this achievement. Vendors who planned and built the 10,000-sq.-ft. expansion are Walker Architects, Inc., and Gilbane Building Company. The proton therapy system was manufactured, installed and commissioned by IBA. The project was managed by the University of Florida Planning, Design & Construction Division. Special thanks to our staff members Bradlee Robbert, director of operations, and Jason Smith, director of facilities, who managed day-to-day progress of the project and our medical physics team members who managed the commissioning of our newest proton therapy device.

This monumental effort demonstrates the University of Florida Health Proton Therapy Institute’s long-term commitment to help people to be cured of cancer so they can go on to live life to the fullest.
