About Us

Mark D. Johnson

HAS, BC-HIS, A.C.A.

Growing up in Cincinnati Ohio, Mark was very close to his Grandpa Kenning. Grandpa Kenning was kept out of WWII due to a severe hearing loss in his left ear, and was never treated for this hearing problem. Due to his grandpas’ struggle, Mark, at an early age became aware of the impact that hearing loss has on a person and their loved ones. Hearing loss made verbal interaction difficult and this was quite frustrating to his grandpa and the entire family.

Immediately after high school Mark served in the U.S. Air Force as a supply sergeant. During his tour of service to our country he spent time in Denver Co., Okinawa Japan, the Philippines, and the Black Hills Mountain region of South Dakota. After his Air Force service, Mark moved to Florida and attended the University of South Florida in Tampa for 4 years. He has been a resident Floridian since 1979.

They have really enjoyed being a regular part of their lives, school activities, and sports involvements.
