    Medical Diagnostics and Supplies (MDS) is a Houston based sleep therapy company run by a family of long-time CPAP users. In business since 2012, “the Billys” as patients know them, have serviced hundreds of customers, providing accurate testing and top quality machines to those with Obstructive Sleep Apnea. We hope you’ll join our family and be with us as we expand to other areas of Texas and the great Gulf Coast, reaching thousands of people in need of good sleep.


    Better Nights

    By providing a steady flow of oxygen to your airways throughout the night, CPAP machines ensure you finally get the rest you deserve.

    Better Days

    Quality rest enables you to hit the ground running and maximize each day like never before. And that’s what we’re happiest to provide: a new take on life through the power of sleep apnea machines.

    Customer Feedback


    "I wish I knew of MDS and Billy 3 years ago when I got my first machine! Easiest transaction ever! The staff is very knowledgeable and makes everything including maintenance super simple. I will be purchasing all of my supplies from them as well as suggesting my doctor switch all of their patients over to MDS. Thank you again!"

    "What a great resource for all things CPAP! They are very professional and extremely knowledgeable about the items needed and also know exactly how to work with my insurance when needed. Keep up the good job guys!"

    "I was so jealous after seeing how this company handled getting my son a new CPAP, that I got them on the phone right away and kept up with them until it was time for me to get my second one. I literally love these guys and am hoping they don't go anywhere because my family and I love working with them!"
