About Johnson's Hearing Centers

Owned and operated by Hearing Instrument Specialist, Holly Johnson, we are dedicated to providing a wide range of hearing services to people of all ages. Before opening Johnson’s Hearing Centers, Holly owned and operated several successful hearing centers in Ohio. She knew she wanted to continue helping people hear better but she was tired of the Ohio winters, so she decided to relocate to Florida.
