The Kleindl family have been helping improve quality of life for the hearing impaired for over 64 years. Their passion for hearing began in 1952 with Donald R. Kleindl, Sr, BC-HIS at the time when batteries were first developed to fit inside hearing devices. Today Kleindl Sr.'s mission has been passed on to his son and grandson, Donald R. Kleindl II, HAS, BC-HIS, ACA, MCAP and Donald R. Kleindl III, HAS, BC-HIS, ACA and continues to expand to include other Kleindl family members and friends who share the same life-long commitment to hearing.
