"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.”

Nice to hear that machine is doing the job on my sleeping. Dr then mentioned two or three other problems I have which I never heard about before. I didn't really know what to ask about this. I feel great and thought if it something really bad, it will be addressed. I do like Dr K as he has helped considerably.
