Christine Butalla, M.S., CCC-SLP

Christine has been at Speech Center since 2012. She graduated from the University of Arizona with her Masters of Science in Speech, Language, and Hearing Sciences in 2011. She completed her Clinical Fellowship year with Panacea Therapeutics, providing services for people of all ages.

Christine has a breadth of experience in the Speech and Language discipline. In addition to practicing as one of our associates, she also works with adults providing speech, language and swallowing rehabilitation. While obtaining her degree in speech-language pathology, Christine completed her clinical research thesis in Childhood Apraxia of Speech, informing our team of the most current techniques involved in treating this challenging speech disorder.

Prior to completing her degree, Christine was a Speech-Language Pathology Assistant and worked with Special Education students within the public school system. Here, she gained valuable experience in the field and background in therapy procedures, treatments, and interventions for school age children. Christine's willingness to go the distance for each patient, whether that means research on a case or extended work with parents, is one of the many reasons we love having her at Speech Center.
