Patient Reviews
Mar 04, 2026
I just left a practice who went through the motions and could not see how to prescribe a short term solution while working to a longer goal. Dr. Sak printed out my various CPAP data and other notes and went over in detail what they meant all the while asking me probing questions. He was highly relatable, insightful knowledgeable and put out a plan of action for me. I left with a sense of hope as opposed to despair from the previous practice.
