Testimonials from Our Clients

  • I love this practice, I was referred by my PCP and it is far from my home, but since I was referred I figured why not. I am so HAPPY I came to the practice. Terry and Michelle are awesome. Making my appointment was easy, no wait, spent time explaining everything, I got to have a home test and received my results in my follow up appointment right away...love this practice!!

  • I had a wonderful experience with the doctor at this location and I highly recommend anybody with any type of sleep issue to go and pay her a visit. She was extremely knowledgeable and filled me in on many things that I had no idea about, regarding sleep. Man, if you snore as bad as I do, which is really really bad, make sure and take a trip here and get it figured out. Thanks so much for all of your guys help and I look forward to getting the flooring issue under control
