He completed his surgical training at Jefferson University Hospital in Philadelphia.  Dr. Bein, in his long professional career, has helped to establish surgical hospitals in both the Middle East and the Far East. 

While Dr. Bein has been performing vascular procedures for many years, recent advances in laser technology combined with his extensive experience, he can offer his patients state-of-the-art minimally invasive procedures.

He offers his patients freedom to enjoy their legs once again with little or no downtime. These procedures once had lengthy and painful recovery ranging from weeks to months. Most of his patients now return to almost full activity the next day. He has been married to his wife and partner in his practice, Maria, for over 30 years. Together they have raised and competed German Shorthair Pointers since 1985.
