ENT Clinic in South Bend, Indiana

ADVENT knows you want to be your best self. We understand your inability to breathe freely and sleep well hinders your quality of life, which is why we pioneered simple in-office sinus and snoring solutions to help you live the life you were meant to live. Our South Bend clinic is located on the outskirts of South Bend just past the well-known University of Notre Dame.

The recent expansion into northeastern Indiana is a result of joining forces with The Center for Sleep and Nasal Sinus Disorders, founded by Dr. Douglas Liepert and his wife, Taimi, who as of May 23, 2022, will rebrand under the ADVENT name. “As the only surgical focused sleep provider in the area, we have grown exponentially over the last two years and recognized partnering with another independent practice was the next step needed to treat our community using the best tools and technology available,” says Dr. Liepert. “ADVENT is an emerging national leader that shares our vision to provide a focused, high quality, patient experience for breathing and sleep issues that is vastly different to the traditional non-focused medical model focused. Our partnership will allow us to bring new technology, increased capacity and elevated expertise to treat people within our community."

They are incredible…they were all so kind. They are very innovative. Everywhere I went in valpo just glanced at me and wanted to just throw me on a cpap machine.

I was pleasantly surprised by the positivity in the office. I just don't experience that much in clinical settings.
