Dedicated to Excellence in Vascular Care Since 1963
Vascular Surgery Associates (VSA) has established itself as a cornerstone of vascular health in Southern California, combining decades of experience with cutting-edge treatment methods. Founded by visionary surgeons in 1963, our practice has grown from pioneering beginnings into one of the busiest and most respected vascular surgery groups in the Western United States.
Our Legacy and Commitment
The origins of VSA trace back to the early 1960s, when Dr. Richard Treiman and Dr. Robert Foran, freshly graduated from their general surgical training, embarked on paths that would soon converge to set a new standard in vascular care. After advanced training under prominent figures in the field, such as Drs. Michael DeBakey and Denton Cooley at Baylor University, and a significant tenure in Oregon, Dr. Foran, persuaded by Dr. Treiman, returned to Southern California. Together, they founded VSA, bringing focused vascular expertise to the region.
This commitment to excellence continues today, with our surgeons leading the way in both traditional and minimally invasive procedures. Specializing in everything from abdominal aortic aneurysm repair to cutting-edge varicose vein treatments, VSA remains at the forefront of technological and procedural advancements. Our team also plays a vital role in teaching the next generation of surgeons at Cedars-Sinai, consistently sharing our extensive knowledge and findings through peer-reviewed journals and multi-institutional studies.
