Hyo Chang W. Arnold, AuD, CCC-A, CH-TM

Dr. Arnold has been practicing audiology since 1990, and her vast experience in providing excellent hearing care spans many settings including top rated University Hospitals, Audiology offices, and ENT practices.

Her areas of clinical expertise include the evaluation and treatment of hearing and balance disorders, and the dispensing of digital hearing aids. In recent years, her clinical focus has been the prescribing and fitting of hearing aids, counseling and aural rehabilitation services.  Dr. Arnold finds her true reward in seeing a person’s life and relationships revived and restored through her professional contribution. As such, her approach is not only about solving her patient’s immediate struggles with hearing difficulties, it is about re-establishing dignity and self-confidence.

Dr. Arnold was born in South Korea. There she earned her BS in Medical Engineering, MS in Electronic Engineering,  and a clinical fellowship of audiology from Yonsei university. She was the chief audiologist at Samsung Medical Center Hospital in Seoul, Korea until she left for further studies in the United States in 2001. She received her Masters in Audiology (MA) from the University of Iowa while working with cochlear implant patients at the University of Iowa Hospitals and Clinics. She then earned her Doctorate in Audiology (AuD) from the University of Florida.  

Dr. Arnold and her family have been residents of the Treasure Coast of Florida since 2009.  She and her family have planted roots in their community and are investing towards a “better life” for many through their work, their volunteering, and their service efforts.

Meet Dr. Arnold: About

Volunteer Humanitarian Services

Abroad & At Home

"Since I was little girl in S Korea, I was so grateful to the missionaries who came to our country and sacrificed themselves for a foreign people. I believe this world can be a better place when we share goodness & kindness with others." 

In addition to seeing patients, Dr. Arnold has enjoyed serving with humanitarian hearing missions in several Northeast Asian countries and in Haiti.  Her family regularly serves in global missions, which has allowed them through their volunteerism to recognize and appreciate their many blessings.

Her family is actively involved in their local church, promoting discipleship and being part of the great commission.  The family enjoys spending time together…doing outdoor activities, volunteering at a local food bank, a homeless ministry, and traveling to disadvantaged locations to share the good news and blessings that they have been given by their creator.


(Mark 4:9)
