Baltimore, MD Hearing Clinic

Baltimore, the largest city in Maryland, has been home to our Live Better Hearing office for the last two decades. Nestled in the Baltimore Highlands area, this city houses the most historical statues and monuments per capita and contains some of the earliest districts in the National Register.

Our office is situated off Annapolis Road and Park Drive, which is convenient for individuals who drive or ride the bus. We offer ample parking in front or behind the building and are close to the Annex Baseball Field and Honey’s Bar and Grill. Because we strive to provide the best care possible for our patients, we are open from 8 a.m. to 4 p.m. on Thursdays.
