Appreciation anecdote for our sleep team:

“I have been working in the sleep medicine since the mid 1990’s and I have worked closely with some of the best RPSGTs in North America. I can confidently say that Nicholas, Ankush and Gurpreet as well as our past team of RPSGTs rank amongst the best of the best, they are highly skilled, keen to learn, professional and universally well respected by the team and the patients. I feel honored and lucky to have this technical team working with us here at the CSHP. Thank you very much for your commitment and professionalism!”  ~ Dr. S
