David Rehfeld, Ph.D.

David M. Rehfeld, Ph.D., is an assistant professor in the Donna Nigh Department of Advanced Professional and Special Services. He is most passionate about school-based, speech-language pathology services for children with communication disorders, especially those with complex communication needs. When he is not actively walking alongside students aspiring to work in the field of speech-language pathology, he is likely playing with his Labrador, reading a good book or out on a run/jog/walk/some combination of the above.

Rehfeld holds national certifications in speech-language pathology and applied behavior analysis from the American Speech-Language-Hearing Association (ASHA) and Behavior Analyst Certification Board (BACB), respectively. He also holds the necessary license/certificate to practice in both of these fields in the state of Oklahoma.
