Douglas H. Cowan, MD

Professional Biography

Douglas H. Cowan, MD, is a board certified Ear, Nose, and Throat surgeon who has been practicing at Ascentist Healthcare since 2008. He specializes in sinus procedures, thyroid and parathyroid disorders, hearing loss, and cancers of the head and neck. A little known fact about Dr. Cowan, he performs more in-office sinus procedures than any other physician in the country. What he is well-known for is his amazing bedside manner and deep care and compassion for all of his patients. Going the extra mile is not something extra, it is part of the patient’s care.

In Dr. Cowan’s free time, he enjoys spending time with his wife, Cara, and their four young children. He also enjoys discovering new ways to empower those around him. He attributes this to all of the mission trips he was fortunate enough to be a part of. He also attributes the love of his career to his supportive wife, mother, and friends and family.

“Everyone I interacted with was very friendly and professional. I was extremely early to my appointment, and they were able to get me in sooner, which was unexpected and lovely. The building itself was very swanky.”

"People with allergies and or anything that deals with your sniffer, should come to this place. Our daughter had surgery here but its relatively quick and not too painful. Staff was very nice. If it helps your loved ones, check into it."

"The care, compassion, professionalism, and friendliness from the doctors and staff are hard to beat. I enjoy each visit and a piece of me will be saddened that I will no longer need to go into the office much longer (because he listens and is great at his job), Dr. Foster listens, cares, and is ready to tackle my concerns. I am grateful to be referred to Dr. Foster and hope others are receiving the same experience!"
