Sleep Apnea

Obstructive sleep apnea has a negative impact on a patient’s health and quality of life, and finding the best treatment option often requires significant effort. Too often patients give up treating this condition due to problems with their CPAP machines, leading to years of suffering. Dr. Allen has helped many such patients overcome these challenges, effectively treat their sleep apnea, and reclaim their health and energy.

-Lena S.
Dr. Allen is a top-notch doctor. After 15 years of chronic sinus problems and numerous visits to various ENTs, he's the best! He spends time with you and never hurries through an appointment. I waited 10 years to have sinus surgery, never feeling comfortable with previous doctors. I'm thankful I found him.

Dr. Allen improved my life by ten-fold. Before my surgery with him, I could barely make it through the day due to sinus issues. After surgery, I can breathe better than ever. His compassion for patients truly shows in every visit.
