When Trizzy Bui arrived at what is now AdventHealth University in 2006, she stepped into more than a degree program. She stepped into a mission.
AdventHealth University helped shape not only her technical expertise in nuclear medicine, but also her passion for advancing healthcare with integrity and innovation. Nearly two decades later, that foundation has carried her to national leadership and recognition, where she now helps shape the future of her profession while championing quality, safety, and compassionate care for patients across the country.
Bui’s interest in nuclear medicine began long before she stepped into a college classroom. As a teenager, she accompanied her grandmother to a nuclear medicine stress test appointment, serving as an interpreter during the visit. The experience sparked a curiosity that never faded. “Everything involved was so interesting to me,” said Bui. “I started looking into the field more and just never lost interest. Almost 25 years later, here I am.”
Bui’s experience at AdventHealth University began in a season of growth and discovery. “Back then, it was probably one of the best times of my life,” said Bui. “I still have lifelong friends from my time there. It’s such a small nuclear medicine world, and I feel I have come full circle.”
After graduating in 2009, Bui entered the workforce during a difficult job market. She questioned her decision and even considered changing fields. Instead, she chose to persevere. “I knew I wanted to do nuclear medicine since I was in ninth grade,” she said. “I’m glad I went this route because the field has completely flourished in the last 10 years.”
Now serving as Nuclear Medicine, Molecular, and Theranostic Technical Department supervisor at the University of Texas (UT) Southwestern Medical Center, Bui oversees operations across eight campuses, ensuring the highest standards of quality, safety, and innovation.
Her current role focuses on quality optimization, regulatory compliance, and advancing hybrid imaging technologies. While she no longer spends every day in direct patient care, her mission remains unchanged. “Even if I’m behind the scenes, I’m making sure we’re providing the highest quality of care with every resource we have,” she said.
Her commitment to excellence recently earned her UT Southwestern’s first Pinnacle Award for Excellence. Selected from more than 300 submissions, Bui was recognized for leading multiple quality improvement projects and presenting her research nationally and internationally, including first-place finishes at major conferences.
Mentorship has become her greatest passion. Recognizing the educational gaps many students experienced during the COVID-19 pandemic, Bui now dedicates significant time to professional development initiatives.
When asked what she loves most about nuclear medicine, her answer returns to the concept of wholeness that she was introduced to at AdventHealth University. “Seeing patients get better,” she said simply. “We’re with our patients repeatedly. When you see therapies working and see them improving, it reminds me why I started this work.”
In addition to her clinical leadership role, Bui contributes to the advancement of her profession through national service as a member of the Nuclear Medicine Technology Certification Board’s Board of Directors. One of just 20 members nationwide, she helps guide the organization responsible for credentialing nuclear medicine technologists across the United States. The board plays a critical role in developing certification exams, maintaining professional standards, and ensuring the field continues to evolve alongside emerging technologies and therapies.
Bui also serves as a representative for the Society of Nuclear Medicine and Molecular Imaging, the profession’s leading organization for education, research, and clinical guidelines.
She credits AdventHealth University for laying the foundation that made her career possible. “If it wasn’t for Advent- Health University and AdventHealth, I wouldn’t be here,” she said. “My program director, my clinical instructor, and all my clinical sites — they had a huge impact on my view of the field. I even went back to AdventHealth University for my bachelor’s degree. I could have gone anywhere, but I chose to go back.”
