Barbara received her Master’s degree in audiology from the University of Virginia and her Doctoral degree from the University of Connecticut with an emphasis in Childhood Hearing Impairment. 

She was the Audiology Manager at a hospital in Chicago for 11 years, took a 4-year “break” to get her Ph.D., then worked at the University of Louisiana Health Sciences Center for 18 years, where she was Director of their Au.D. Program, before moving to Hawaiʻi.

In Hawaiʻi, she worked full-time for the Department of the Navy as an Occupational Audiologist for 8 years, and now works part-time for the University of Hawaiʻi Communication Sciences Department and Clinic, and one day a week at Kapiʻolani Medical Center for Women and Children.

The DOE has contracted her services through the University of Hawaiʻi.

She has experience with and enjoys working with patients of all ages.  She started the first newborn hearing screening program in the State of Illinois, and worked with many other hospitals to get their newborn hearing screening programs working.  She has started two hearing aid dispensing programs, provided audiology services in a skilled nursing facility and took the lead in authoring and securing the Doctor of Audiology (Au.D.) program for the University of Louisiana Health Sciences Center.

She believes her biggest attribute is that she is a boots-on-the-ground person.  She does not just talk about theory about things; she does them on location with real patients and graduate Au.D. and SLP students.
