Karthik Kanagarajan, M.D.

“My passion is for perfection!  My goal-oriented approach and strong interest in the sciences attracted me to the medical profession at an early age. I have always worked hard at applying science in a way that provides compassionate care to my patients and builds my clinical skills.  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.

Pulmonary and Critical Care Medicine fascinates me as I always considered myself “a problem solver” in demanding situations. I enjoy treating patients with complex medical problems in the ICU and I try hard to keep it simple for patients and families to understand.

Sleep disorders and breathing problems frequently exist together.   My mission is to provide the well-rounded care that my patients need in getting a good night sleep and being able to breathe well during both the day and night.”
