About Us - Gateway ENT in St. Louis, MO
SMELLING Like Roses
In 1979, our founder, Dr. Tom Donovan started Gateway ENT. Dr. Donovan, one of the most beloved and well-respected doctors in St. Louis, wished to start a small, friendly, family-oriented ENT practice. He wanted to offer academic quality care with a more personalized approach. Although he has retired, that tradition carries on today.

Dr. Yoon found an issue that other doctors hadn't been able to pinpoint. I had no problem getting an appointment to fit my schedule even though I was a new patient. The follow up visit was just as easy to schedule and Doctor Yoon and his staff are always prompt with getting you in and addressing the issue at hand. Dr. Yoon has been able to answer all of my questions and concerns to my satisfaction thus far.
