Dear Gary,



It has been nearly four months since I received the Herbst device for my sleep apnea problem. As I told you the day after receiving it, it has radically improved the quality of my life. I use it faithfully every night and would not get a full night's sleep without it. read more

Dear Dr. Greenberg,



This is just a note to say how very grateful I am that you fitted me for an appliance for my sleep apnea. My orginal intention was to have this appliance in case I was unable to use my CPAP machine due to a power outage. Imagine my delight when I discovered that the appliance worked even better than the CPAP machine. I think that only a person who has experienced the grim reality of debilitating fatigue due to sleep deprivation can truly understand just how very grateful I am. read more
