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!!

My wife and I have been looking for a good sleep solution. We came across Sleepwerx and were pleasantly surprised how fast we were able to get an appointment. Terry and Michell were very helpful and we are excited about finally getting some resolution to my snoring and our sleep challenges.

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
