We do make allowances for emergency referrals, but walk-ins are not encouraged.

New patients are scheduled to allow for additional examination time. Please arrange routine appointments as far in advance as possible.

During the day, our surgery scheduler meets with patients who are in the office and who need to schedule surgery. Dr. Rao usually operates on Monday and Thursdays. He has admitting and operative privileges at Swedish Medical Center, Littleton Adventist Hospital, Porter Adventist Hospital, Surg Center at Dry Creek, Centrum Surgical Center, and Sky Ridge Medical Center.

  • nasal endoscopy
  • flexible nasopharyngoscopy & laryngoscopy

Our endoscopic equipment not only allows your physician to view the anatomy relevant to your medical problem, but allows recording of images and video to educate you, compare examinations, and share with your primary care physician. Our examination rooms provide a quiet, private, and comfortable setting for your examination. Examinations of the nose and larynx are done comfortably in the office with topical anesthesia only, making it possible to return to work the same day as your procedure if you so choose.  We also have to ability to perform nasal and sinus procedures on select patients in the office setting.  Our highly trained and experienced nurses will make your allergy skin testing and treatment programs as comfortable and convenient as possible.

South Denver ENT & Allergy transitioned to an Electronic Health Record in February of 2011 in order to provide the highest level of patient care and privacy.
