It took me months before getting the correct physician for my sleep apnea from my insurance company. By that time I was totally stressed, as I was planning on going on a group trip and needed my mouth guard replacement ASAP. My physician recommended DSAC and they were wonderful. I was impressed with their thoroughness as well as timeliness. They accommodated me within days of departing. I was able to relax and not worry about snoring and keeping my friends awake. Their follow-up is great too. I felt like they truly cared about my well being. Dr. Keith Valachi is top notch and his staff is the best. I’m not great with being comfortable around doctor offices and he and his staff have a great way of calming you down and making you feel at ease. They explain everything thoroughly. I would highly recommend them as the top sleep apnea clinic in Portland and the metropolitan area. I plan to use them even when I move to Florida.
