Kristen Rubin, Au.D.


Dr. Kristen Rubin, Au.D.

Dr. Kristen Rubin is the owner and head audiologist at Keystone Classroom.  She was drawn to the field of Audiology because it gave her the ability to greatly improve a person’s quality of life.  A Warwick native, after earning her Bachelor of Arts Degree in Communication Disorders from the University of Connecticut followed by her Doctorate in Audiology from Salus University in Pennsylvania, she knew she wanted to return to the Ocean State. 

Dr. Rubin connected with Dr. James Healey, the former owner of the educational audiology program.  As Dr. Healey approached retirement, Dr. Rubin and her husband Scott took ownership of the business.  Scott is now the office manager at the Keystone Audiology clinic and Dr. Kristen Rubin runs Keystone Classroom and also sees adult patients in the clinic.

When outside of the office, Dr. Rubin enjoys spending time with her family.  She and her husband have three children, Henry, Charlie, and Madison, and are in a busy stage of life!  She enjoys trying to keep up with her kids, fall New England weather, and family trips to Story Land & Santa’s Village.
