Ramy Mena
Ramy has taught ultrasound physics in sonography schools. He is also the founder of Sonotec Imaging, a multi-location diagnostic ultrasound practice in Southern California that also trains sonography students as a clinical externship site.
Every program is taught the way the material is actually used at the scanner: small lessons, constant testing, and no moving on until the foundation is solid.
