Theresa is a certified speech-language pathologist and auditory verbal therapist who has specialized in serving children who are deaf and hard of hearing for over a decade. Theresa completed her bachelor's degree at Loyola University in Maryland and her master's degree at The George Washington University in Washington, D.C. During her time at The George Washington University, she was awarded the Cochlear Implant Fellowship at The Alexander Graham Bell Association for the Deaf and Hard of Hearing.

Throughout her career, Theresa has provided home-based, center-based, and school-based services for children with hearing loss. She has experience in Listening and Spoken Language, American Sign Language (ASL), and Total Communication. Theresa strongly believes that parents should be the decision makers when it comes time to choosing a communication approach for children with hearing loss, and she firmly supports families throughout the process. Whether parents have chosen to use Listening and Spoken Language, American Sign Language, Total Communication, or any other approach, she partners with families and coaches them on how to provide their children with strong language environments.

Theresa has presented at national and international conferences about best practices for children with hearing loss. She also provides mentoring to professionals seeking Listening and Spoken Language certification, a rigorous 3+ year process which she completed in 2012.

Theresa currently owns and operates Sound Speech, which exclusively serves deaf and hard of hearing children and their families. She lives in Hunterdon County, New Jersey with her husband, three young children, and very active goldendoodle!
