By Dr. Kellar taking a fresh look at my ongoing medical issue, and providing a new course of action for treatment, will hopefully lead to a path of long term recovery.

I was there to check the effectiveness of my CPAP and its affect on my sleep apnea. I had a pretty good idea of what to expect, but was pleasantly surprised by the details downloaded from my unit. The doctors and staff are polite, friendly and knowledgeable. What more can one ask?
