AAC Trainer

Liza received her bachelor's degree from California State University Northridge. She started her education studying American Sign Language before ultimately changing course to Communication Disorders and Sciences. Interacting with the deaf community solidified her belief that just because somebody doesn't speak, does not mean that they don't have anything to say. During her studies, Liza felt very drawn to AAC and desired to learn even more about the field. As a new member of the CTEC team, Liza is passionate about communication access and firmly believes that everybody has a right to be heard. These are beliefs that she brings to her work as an AAC trainer. It is Liza's desire to help people of all abilities gain access to communication and share their unique personalities, thoughts, and opinions.
