As far as the technicians & the sleep doctor. It was an amazing experience. The support staff at the desk, is the most unprofessional, rude & disrespectful. " Angela " spoke in a very condescending tone, spoke to these elderly patients there in a very disrespectful way. She was also arguing with me when I told her her tone was atrocious. I did speak to the owner. She will come across the wrong person one day.
