Houston's dual sinus & sleep specialist • Board-certified ENT • Fellowship-trained Rhinologist

Living with chronic sinus issues or disrupted sleep impacts every part of your life. Dr. Shawn Allen specializes in minimally invasive procedures designed to restore breathing, sinus function, and sleep quality.

Whether you're battling sinus infections, congestion, or obstructive sleep apnea, his approach combines advanced imaging, comfort-first techniques, and personalized care to help you breathe—and sleep—better.

Dr Allen did my sinus surgery a few years ago and I continue to see him once a year for my sinus rinse medications and I have not been sick or had a sinus infection since
I actually do not get sick anymore with the flu or cold because as soon as I feel a little congestion, I use the medication in my sinus rinse and I feel much better. I am so grateful for Dr Allen and how he has taken care of me for the last few years.

Dr. Allen performs a detailed exam, reviews your imaging, and explains your options. He takes time to answer questions and ensure you feel confident.

What Patients Are Saying

Dr. Allen is a caring, compassionate doctor. He takes the time to listen to your concerns and answers all your questions in a manner that you can understand. I was referred to Dr. Allen after seeing another ENT for several years. Following consultation, Dr. Allen performed revision sinus surgery. After surgery my symptoms improved greatly. I’m able to breathe better, headaches have improved and the number of sinus infections has been greatly reduced. I would highly recommend Dr. Allen if you are having problems with your sinuses.

Before meeting Dr. Allen I had visited two specialists in otolaryngology and I had never felt the empathy and confidence that both Dr. Allen and his entire team gave me. They explained to me in detail what I had and the surgery I had to do. I had never visited a doctor who had such a direct and explicit treatment with a patient, his whole team is extraordinary, From the person who attends at the front desk to his nurses, especially Crystal, she is undoubtedly the best! Thank you Crystal for helping me and making me feel at home, your professionalism and attention is unsurpassed! Don't hesitate to visit Dr. Allen, you won't regret it. He is the best ENT in Houston, now my nose is healthy thanks to him. Thank you again!

Roxana Gil

Nurse Crystal, is so awesome as well! Overall hands down a wonderful experience with my surgery. He will forever be my favorite ENT!

I had sinus problems off an on for over a year. About March of this year my sinuses were so infected that my tooth got infected as a result of the harsh sinus infection. I had sinus surgery a month ago and I have never FELT BETTER!! Dr. Allen has made easy to follow after care instructions for his patient for after surgery, that has made recovery such an easy process. I would also like add he has an AMAZING STAFF. Dr. Allen and his staff sincerely care about each of their patients and their conditions and recovery., This is such a comforting feeling as a patient. THANK DR. ALLEN AND STAFF

Danyale Mack

Dr. Allen and the rest of the team provide incredible care. He quickly diagnosed the issue during the first session and laid out the best treatment plan. My insurance decided last minute that the chosen surgery center was out of network, but Dr. Allen came to the rescue and was able to reschedule at a different location for the same day, which ultimately saved me thousands. He and Crystal, his medical assistant, are incredibly responsive, more so than any other doctor I’ve had. Great experience, and my nose works better than ever before.
