I went to schoola nd have been licensed in the state of VA since 1983,  I worked hard to develop my skills and continue my education  I dont believe that hospital trained Assisstants are trained and supervised in the same way i was.  so many things can be wrong with an ivc. if you want the job done correctly have the correct staff,  Virginia has plenty of places and ways to be trained as a technician.  invest in our profession use a licensed technician .
