Dennis Atherton began his career in the healthcare field as a Respiratory Therapist. His employer had purchased a cardiac ultrasound machine and could not find a cardiac sonographer, so they asked him if he was willing to learn cardiac echo, and he agreed. He has now been working in the cardiac ultrasound field for thirty-five years. Dennis is currently employed as the Director of Cardiac Imaging and Diagnostics for Maine Medical Center in Portland, Maine, and has been employed there for fifteen years.

Maine Medical Center performs over 20,000 scans a year, and this Intersocietal Accreditation Commission Echocardiography lab is involved in TAVR, clip, melody valves, ASD closures, LVAD devices, and a host of other interesting and challenging procedures. Maine Medical Center’s echo lab also supports the Southern Maine Community College cardiac sonography program.
