In September 1998, because of a friend's recommendation, I came to Dr. MacMahan with an earth shattering snoring problem, serious sleep apnea and an impossible constantly running nose. Quickly I was tested and diagnosed with airway obstruction, sinus issues, and many common allergies. He recommended protocol of a series of minor outpatient surgeries, medication and sleeping with the sexy Cpap machine gave me relief in all three areas of my respiratory difficulties in short order. During the process, I came to understand that... read more

I have been a patient of Dr. John McMahan for over 2 years, suffering from chronic severe sinus infections.

Dr. John McMahan and his team at Northwestern Nasal have been nothing short of Godsent. When I called to come in two years ago, I had been suffering from chronic sinus infections for the past 5 years, and had been on and off antibiotics and steroids. I was miserable. Dr. McMahan has continuously treated me with skill and care. When I first arrived, Dr. McMahan took CT scans and diagnosed my issues. When a course of medication did not fully treat my infection, he recommended surgery. At the time, I was not ready and wanted to... read more

I have been a patient of Dr. McMahan's for the past 25 years. Through 2 surgeries (to fix a deviated septum and a second one to fix damage done in an accident) I can say he is one of the best in the business. The program he has put me on for allergy treatments has made sinus infections a thing of the past.

When I realized my cold lasted too long and was confined to my head, I called. Doctors helpers promptly made an appointment. When I arrived, the office staff was helpful and pleasant. The doctor listened to my complaints, asked me questions, made a correct diagnoses, and effective order and relieved me. Excellent treatment and results. I recommend highly.
