“Health is wealth and every one of us should invest in it to be able to lead healthy life. I strongly believe in patient education about their health. An informed patient can make better health care decisions, which will improve health care outcomes.”
While taking care of my grandfather during his last months of life, I realized how important it is to have a medical specialist in the community. I became a medical provider because I want to provide the best care possible in a safe, efficient, effective and compassionate manner for my patients.
Philosophy of Care
A learned patient can make better choices for their health. My philosophy is to make complex medical diagnoses and treatments simple to understand for patients in order to help them make better-informed health care choices.
My favorite part of medicine is listening to my patients to understand the natural history of disease process.
