Our History: Changing Lives Through Better Hearing


Bieri Hearing Specialists was founded in 1952 by Gottlieb Bieri. He wanted to help his parents and others with hearing loss. His daughter, Cathy Bieri Ryan, Au.D., later took over the practice, expanding it from a small home office to five locations across Mid-Michigan. Cathy’s dedication to patient-centered care and community service set the standard for excellence. Today, we carry on her legacy by providing compassionate, patient-centered care.


A New Chapter: Focusing on the Future


In July 2023, Bieri Hearing Specialists started a new chapter under Sarah Roggenbuck and Dr. Melissa Menzies. Together, they bring over 40 years of experience in hearing healthcare, advancing the practice’s mission through innovation and empowering patients. Their vision focuses on fostering a supportive team and delivering life-changing care.


Bieri Hearing Specialists now has five locations: Saginaw, Frankenmuth, Midland, Bay City, and Clare. Our team of 15 professionals offers services like:


  • Hearing Evaluations
  • Hearing Aids
  • Wax Removal
  • Tympanometry
  • Video Otoscopy
  • Real Ear Verification
