I believe in a col­lab­o­ra­tive approach to patient care with shared deci­sion mak­ing. This starts with lis­ten­ing care­ful­ly to my patient’s symp­toms and con­cerns to bet­ter under­stand their med­ical con­di­tion. I strive to edu­cate my patients regard­ing their diag­no­sis and pro­vide them with a thor­ough under­stand­ing of the avail­able treat­ment options. I hope to select a treat­ment plan with patient input that will deliv­er the best pos­si­ble clin­i­cal out­comes by tak­ing into con­sid­er­a­tion their health care goals and lifestyle. It is my priv­i­lege to be part of your health care team.

Dr. Ung spe­cial­izes in the treat­ment of nasal and sinus dis­or­ders with par­tic­u­lar inter­est in chron­ic sinusi­tis, nasal poly­po­sis and nasal obstruc­tion. As the only fel­low­ship trained sinus sur­geon prac­tic­ing exclu­sive­ly in DuPage Coun­ty, he has excep­tion­al exper­tise in endo­scop­ic and min­i­mal­ly inva­sive sur­gi­cal tech­niques to treat chron­ic sinonasal con­di­tions. Dr. Ung crit­i­cal­ly eval­u­ates new tech­nol­o­gy and endeav­ors to bring the lat­est tools and tech­niques to the com­mu­ni­ties he serves. He was the first in DuPage Coun­ty to per­form bal­loon sin­u­plas­ty, place Pro­pel steroid elut­ing stents dur­ing sinus surgery and implant Sin­u­va for patients with nasal poly­po­sis. He has exten­sive expe­ri­ence in com­put­er assist­ed, image guid­ed surgery and pow­ered instru­men­ta­tion. Dr. Ung con­tin­u­ous­ly seeks to expand his knowl­edge base through addi­tion­al cours­es and train­ing pro­grams. Dr. Ung under­stands the suf­fer­ing that peo­ple with nasal and sinus dis­ease expe­ri­ence and knows relief of these symp­toms can bring dra­mat­ic improve­ment to their qual­i­ty of life. He strives to edu­cate patients regard­ing their dis­ease process and poten­tial treat­ment options so they may under­stand the goals of ther­a­py and have real­is­tic expec­ta­tions of out­comes. Through this dia­logue, Dr. Ung hopes his patients play an inte­gral role in the deci­sion mak­ing process regard­ing their treat­ment, whether med­ical or sur­gi­cal. Dr. Ung grad­u­at­ed magna cum laude with high­est hon­ors from Har­vard Uni­ver­si­ty. He went on to earn a med­ical degree from the Wash­ing­ton Uni­ver­si­ty School of Med­i­cine in St. Louis while also gar­ner­ing a research fel­low­ship from Har­vard Med­ical School. After an intern­ship in Gen­er­al Surgery at Brigham and Wom­en’s Hos­pi­tal, Dr. Ung com­plet­ed his res­i­den­cy in Oto­laryn­gol­o­gy – Head & Neck Surgery at Har­vard Med­ical School. He then fin­ished an inten­sive, spe­cial­ized fel­low­ship in Rhi­nol­o­gy and Sinus Dis­ease at the Mass­a­chu­setts Eye and Ear Infir­mary. Fol­low­ing his fel­low­ship, he prac­ticed for sev­er­al years as an attend­ing physi­cian at the Mass­a­chu­setts Eye and Ear Infir­mary. As part of his duties there, he lec­tured at Har­vard Med­ical School and was involved with med­ical stu­dent and res­i­dent edu­ca­tion. Includ­ed in his hon­ors is a teach­ing award from Har­vard Uni­ver­si­ty. The results of his research have been pre­sent­ed at nation­al and region­al meet­ings and pub­lished in peer-reviewed journals.
