"My passion is for perfection. I strongly believe that patients deserve truthful and honest answers to their medical problems, and I strive to achieve that with every patient I see. My goal-oriented approach and strong interest in the sciences attracted me to the medical profession at an early age, and I work hard to apply science in a way that provides compassionate care to my patients and builds my clinical skills."

“Pulmonary and Sleep Medicine fascinates me as I always considered myself ‘a problem-solver’ in demanding situations. Sleep disorders and breathing problems frequently exist together. My mission is to provide the well-rounded care my patients need to get a good night's sleep and be able to breathe well during both the day and night.”

Excellent experience!

I came in for a sleep study. The final outcome was that I snore. Guess what? I've known that for 30+ years. Whatever I paid for my appointments was not worth the outcome/diagnosis. No high-tech study was needed for me to know that I snore. What I need to know is how to improve my sleep; I was not provided this information however. It seems like the primary function of this process is to determine if one has sleep apnea and needs a cpap machine. I think I saw from your own website that something like 5% of adults have sleep apnea. That seems like a rather slim number to base an entire practice on.
