Welcome to Metro Sinus

Our Story

Founded in 2012, Metro Sinus has grown to become the bi-state region’s only nasal & sinus center offering the full scope of minimally-invasive, in-office ENT solutions. Metro Sinus is affiliated with and located within Midwest ENT Centre, the region’s busiest, most comprehensive and highest-rated ENT private practice.

Founders Dr. Matthew Conoyer and Dr. Karen Boone have been performing in-office balloon sinus dilations since 2011. They have more combined years of experience than anyone in offering Balloon Sinuplasty–but something else makes Metro Sinus truly unique in the St. Louis area.

Our physicians know that no one procedure, approach or treatment is appropriate for every patient or condition. Metro Sinus offers a wider array of proven office-based ENT technologies than anyone–and has the experience and expertise to match those solutions to our patient’s needs.
