Norman N. Bein, MD FACS

Dr. Bein has been practicing as a surgeon for over 30 years.  He is Board Certified by the Board of American Medical Specialties and has had extensive experience in Vascular, Thoracic and General Surgery. Additionally, he is a Registered Vascular Technician and performs all his own vascular studies. 

His surgical studies were at Rush Presbyterian St. Luke's in Chicago before entering the United States military.  Dr. Bein served as a Captain in the US Army Medical Corps for two years. 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 is able to offer his patients state-of-the-art minimally invasive procedures. He performs and oversees many types of laser procedures in his office including treatments for varicose and spider veins, tattoo removal and skin rejuvenation.  He continues to study advances in his chosen field by attending in depth meetings with the American Venous Forum, the
American College of Phlebology and the International Vein Congress

He offers his patients freedom to enjoy their legs once again with little or no downtime. These procedures once had extensive 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.

Maria is a Registered Nurse and the Clinical Director of Vein Specialties. She has been married to Dr Bein for over 30 years. She was born in Australia where she earned her nursing and midwifery degrees. Maria specialized in nursing children with burns and was on the Australia and New Zealand Burns Association Board. From there she was recruited to Saudi Arabia to help establish their burn program at Al Hada Hospital in Taif. It is here she met Dr. Bein. 
On their return to the USA, Maria worked extensively with the elderly and wound care. She was Clinical Director for a large elder homecare division in Massachusetts. Her keen interest in skin care and health allow her to offer sclerotherapy and topical laser for spider vein removal. She has had extensive training and experience in this field and continues to attend intensive educational and training programs with the American Venous Forum and the American College of Phlebology.
