Dr. Glasner is a voice, upper airway, and swallowing-specialized speech-language pathologist. He received his clinical graduate training at Delaware Valley University. He completed clinical externships at the Johns Hopkins Voice Center and the Duke Voice Care Center, and completed a voice and upper airway clinical fellowship at the Lions Voice Clinic at the University of Minnesota. Prior to becoming a speech-language pathologist, he held academic positions in music and speech-language pathology, and taught singers all around the world—including singers at the Metropolitan Opera and on Broadway—for over a decade.
Dr. Glasner enjoys collaboratively and empathetically helping patients and clients with a variety of voice, upper airway, and swallowing conditions through their rehabilitation journey. His clinical interests include singing voice rehabilitation (all styles), chronic throat pain, gender affirming voice care, the aging voice, and neurodegenerative voice disorders.
