Byron Beplay, AMGCD Program. CDA Tech goes way past anyone’s expectations of a trade school. From the very first day this staff will be with you step-for-step making sure you feel exactly like family and helping you to succeed. I loved this school and everyone here. So take it from me: Come join the CDA Tech commercial diving family and be a part of this awesome industry! Trey Lancaster, AMGCD Program. I went to a trade school and got my welding certification and that was not enough. I found CDA technical Institute online and decided to become a Commercial Diver because of my love for the water. I had the best time going through CDA Technical Institute and I would definitely recommend this school to anyone looking for a career in Commercial Diving. Brett Lamb, AMGCD Program.
