Professional Hearing Center, located at 427 Jane Ave., Union, is marking its 35th anniversary.
Dr. Cindy Modrosic, Au.D., also is celebrating earning her doctorate of audiology from A.T. Still University.
Professional Hearing Center offers audiology services, hearing exams, hearing aids, hearing protection and assistive devices.
“What is available to audiologists has changed,” said Modrosic, adding that she has upgraded equipment and more testing is available than has been in the past.
Modrosic also offers speech mapping, or hearing aid verification, to make sure hearing aids are set properly.
The biggest change in audiology, she said, is the rate at which hearing aids change.
“They’re upgrading every six months instead of every couple of years,” she said.
Professional Hearing Center has expanded services to cater to veterans through the Veterans Administration or the Veterans Choice Program.
Modrosic can complete compensation and pension evaluations through the VA and hearing aid fittings through the VA and Veterans Choice.
“With new equipment I purchased this year, I can do a better job of testing small children,” she added.
The tympanometer, which has otoacoustic emissions (OAE), can test youth who are too young or can’t respond to sound by raising their hand or through playing games in a booth.
Modrosic sees patients of all ages, from children up to a patient who is 100 years old.
Looking forward, she said her goal is to continue to provide excellent service to patients, as well as to keep up with the ever-changing field.
“I want to make a positive impact in my patients’ lives,” she said, adding that watching technology change has been fascinating.
The practice was started in 1982 by Liz Wilmesherr, an audiologist. At the time, it was located on Church Street and was one of the first audiology practices in the St. Louis area, Modrosic said.
From 2002-2006, Modrosic worked at the center under Wilmesherr before starting an audiology practice at St. Anthony’s Medical Center, St. Louis.
In January 2010, Modrosic purchased the practice from Wilmesherr and moved it to its current location in December 2014.
Originally from O’Fallon, Ill., Modrosic moved just outside Franklin County in 2001.
Modrosic earned a bachelor’s degree in communication disorders from St. Louis University. She earned a master’s degree in speech and hearing science from the University of Illinois and a master’s degree in audiology from Central Institute for the Deaf at Washington University, St. Louis.
To continue her education, Modrosic earned her doctor of audiology from A.T. Still University this past August.
Modrosic and her husband Bill, a firefighter, have two sons, Liam, 10, and Sean, 7.
They reside near De Soto, in Jefferson County.
