Doug, along with his staff of RVTs' trained specifically in venous anatomy, pathophysiology and treatment of venous insufficiency, has provided diagnostic ultrasound and training to physicians and sonographers for over 15 years.

Doug Marcum,RDMS,RDCS,RVT,RPhS is President/Owner of Advanced Ultrasound Consultants and has been practicing diagnostic ultrasound for over 24 years.  Doug is board registered and has practiced multiple ultrasound modalities but his passion and focus lies in Vascular Sonography, earning the Advanced Practice Sonographer(APS) designation in Vascular Technology in 2001.  In 2010, Doug was chosen to to participate in taking the "pilot" examination for CCI's (Cardiovascular Credentialing Institute) Registered Phlebology Sonographer (RPhS) board examination where Doug was awarded the RPhS credential in March, 2010. 

Since 2000, and with the evolving trends in vein therapy, Doug's primary focus has completely progressed into venous insufficiency and phlebology where he has dedicated himself to the field of phlebolgy.  Doug has assisted in over 15,000 laser and radiofrequency vein ablation procedures and innumerable ultrasound guided foam sclerotherapy (UGFS) procedures. Doug also had the privilege of assisting with "Beta" testing of Covidien's (VNUS) radiofrequency perforator stylet (RFS) catheter prior to it's formal release.

 Doug also serves as a consultant for physicians and sonographers on both a regional and national level for optimizing vein therapy procedures and scanning techniques in their practice.  Doug has contributed to several clinical ultrasound research projects, including a pharmaceutical study for an anti-coagulant/thrombolytic agent.

 Currently, Doug and his Medical Advisor, John Horowitz, M.D. have developed the "TumesX" tumescent anesthesia delivery needle that will aid in the ablation treatment of venous disease. (see image to the right) The "TumesX" needle not only allows the treating physician more latitude in tumescent infiltration, the "TumesX" has shown clinically to decrease the number of tumescent needle "sticks" while delivering a more robust coverage of anesthetic.  The "TumesX" also has an distinct echogenic tip allowing for easier location under ultrasound guidance.

Doug's acclaimed teaching background includes being named the clinical instructor of the year in 2000 and 2001 from Florida Hospital College of Health Sciences in Orlando, FL.  Doug also has been published in the Journal of Vascular Technology and is active in many societies including the Society of Diagnostic Medical Sonographers (SDMS),  The Society for Vascular Ultrasound (SVU), and the American College of Phlebology (ACP).  Doug is also a highly respected speaker who has spoken on a local, regional and national level on multiple occasions. Most recently, he was invited faculty for the 2006 annual Society of Diagnostic Medical Sonographers (SDMS) meeting in Denver, CO., 2007 SDMS meeting in Las Vegas, NV and the 2009 meeting in Nashville, TN.
