"Thank you Robert! I have ordered 4 of your 4th edition books for my organizations here in the past but recently they’ve been removed from Amazon. I have a copy of your book at each of the 5 vascular labs I manage and they are priceless. Both new and experienced technologists refer to them regularly. To date we have not found a better book to support our continuous learning. Thanks for all the great work! " Konrad P. "Rob, Any chance you have written a text on abdominal sonography? I just spent an entire day trying to comprehend the liver chapter in my text. I also just read the first Venous Chapter (Chapter 5) in about an hour and a half... I just wanted to let you know how much I am enjoying it already. It's so much easier to understand than the lengthy, verbose texts I am so used to spending double the time attempting to decipher. It is nice to have something in plain English to learn from. THANK YOU! Sincerely, Cali Taylor" University of Colorado Hospital in Denver - Sonography Student "Rob, I LOVE the new edition of Techniques in Non Invasive Vascular Diagnosis. It is GREAT!!!!!!!!!!!!!!!!!! I haven't had a chance to actually read the whole book, but from what I have, it is great. I can't wait until the Instructors CD-ROM. Please let me know when it is available. Thank you and great job." Susan Thrasher RVS, RDMS, RT (R) Program Director Diagnostic Medical Sonography VIRGINIA COLLEGE in BIRMINGHAM "Rob, I have found your previous PowerPoint slides of immeasurable value in teaching vascular ultrasound. Your newest edition of slides is even better than the last. You have added and expanded on so many concepts that I am thinking of scrapping my supplementary PowerPoint presentations and using yours exclusively. Great job on this new product. It is tremendously helpful."
