As a rhinologist, Dr. Koszewski diagnoses and treats people with nose and sinus disorders. These include frequent sinus infections, thick drainage, inflammation, facial pressure and pain that impacts their ability to function well in daily life.

During initial visits, Dr. Koszewski talks with patients about their symptoms and how their condition impacts their quality of life. He performs exams and tests and offers both surgical and nonsurgical treatment options.

To advance skull base surgery, Dr. Koszewski researches patient outcomes and new techniques to improve how patients feel in the long term.

During his free time, Dr. Koszewski enjoys running, reading, traveling and spending time with family.

I work to give my patients promising treatment choices that will help them feel better and improve their quality of life.
