After several years of not sleeping well, I was diagnosed with mild sleep apnea about a year ago. After reviewing options and talking with people who use the C Pap machine, I decided to try the dental appliance. I have been using it a couple months and am sleeping much better. Dr. Valachi and his staff are professional, competent, friendly and always willing to listen and accommodate any issues or problems I might have. I would recommend Dr. Valachi and the clinic to anyone who wants to look at options for sleep apnea.
