Marshalltown Team

Duane Flagel

Duane Flagel –  Co-Founder/Owner

My son-in-law, Taylor Parker, and I started Iowa Hearing Aid Centers in 2002 and have grown to one of the largest independent hearing aid dispensing companies in the country. We specialize in Concept hearing aids, which allows us to become experts in one product. As a user of hearing aids for over 30 years, I am committed to helping fellow Iowans who also suffer a hearing loss, and I’m proud of our excellent reputation for customer service. Over 30% of all new patients have been referred to us by current patients!
