In patients' words

"The staff was awesome. The sleep lab itself has a lot to be desired. They only have 1 bathroom for 4 patients. My wife had to stay with me... She had to sleep in a recliner. The sanitization here is horrible. They reuse their sleep mask."

"I stopped seeing Dr. Allen when he told my husband that I was like a cheap date when questioned about the adverse reaction to twilight anesthesia. Totally unprofessional."
