Dr. Preston Smith

Dr. Preston George Smith is a board certified vascular and interventional radiologist. Following his graduation from the University of Texas Medical School in the Texas Medical Center in Houston, he went into a residency program with the sole purpose of obtaining the highest level of endovascular surgical and interventional radiology training, knowing that minimally invasive therapy was the future of medicine. After spending five years completing his residency at Rush University Medical Center in Chicago, he entered the prestigious vascular and interventional radiology fellowship at the Medical College of Wisconsin. There, he developed and acquired state of the art minimally invasive techniques to treat peripheral vascular disease, cancer, men’s and women’s health conditions, among other disorders.
He dedicates 100% of his time to direct patient care through medical and minimally invasive procedures, instead of splitting time with general radiology duties of interpreting diagnostic scans. He has remained steadfast in his vision that to truly become an expert subspecialist, one should fully immerse oneself in the craft. Subsequently, he has brought many state-of-the-art therapies to his patients.
In 2017, he was one of the first physicians to start performing prostate artery embolizations in Texas and to surpass 100 patients treated. He has started programs to treat critical limb ischemia and liver cancer through endovascular surgical techniques in the outpatient space. Recently, in 2021, he began performing genicular artery embolizations, an emerging therapy of knee arthritis. In 2022, he founded Summit Interventional Radiology, a comprehensive, stand-alone interventional radiology practice, the first of its kind in Austin, Texas. His vision is to provide the highest level of care to his patients through endovascular surgical and other minimally invasive techniques, as well as raise awareness about these less invasive outpatient techniques.
