Many years ago, I received my first sleep apnea oral appliance directly from the pioneer of the technology Dr. Gail Demko. When she retired, I was somewhat unsure that anyone could fill her shoes, but Dr. Cohn and her team have done the impossible: Not only did she keep Dr. Demko's the world-class, life-changing, sleep apnea therapy but also improved and expanded its delivery. Sleep Apnea Dentists of New England now operates in a conveniently located state-of-art professional office that somehow even continues Dr. Demko's home office design that allowed patients to observe a relaxing bit of nature through large picture windows while being treated. Dr Cohn's level of professionalism extends to every member of her staff, including, most recently the extraordinary level of customer service provided by her Receptionist/Billing Coordinator/Office Manager Silvia. While talking insurance referral and co-pays with her counterparts in my primary care doctor's office, she went out of her way to advocate on my behalf. Her hard work should be commended, as she is truly a beacon of hope in a sea of increasing incompetence. If you have sleep apnea, and a CPAP machine hasn't helped, I will highly recommend Sleep Apnea Dentists.
