Abigail Sedenka, Au.D.

Owner/Doctor of Audiology
As a native Mainer, Dr. Abigail Sedenka did what a lot of us do and headed out of state for college. She attended Syracuse University for her undergraduate education then both the University of Rhode Island and the University of Connecticut to earn her doctorate in audiology. However, it didn’t take long for her to realize that Maine was where she wanted to be, so she headed home to the Pine Tree State. Since then, she has worked in a variety of settings in Southern Maine and has practiced audiology for about 15 years.
