Management Team

Virtual Vein Center was created with the goal of assembling the best physicians, sonographers, educators and scientists and to provide a method to disseminate that knowledge and materials to practitioners around the world. For decades, we have been exceedingly active in vascular ultrasound and phlebology including the American Venous and Lymphatic Society ("AVLS"), {formerly the College of Phlebology ("ACP")}, Society for Vascular Ultrasound ("SVU"), American Venous Forum ("AVF"), Vascular Disease Foundation ("VDF"), Intersocietal Accreditation Commission ("IAC") as well as others.

We actively practice phlebology as well as lecture and teach throughout the USA and internationally. We have a special passion for venous disease and hope that you will find this site informative and valuable to your daily practice.
