About

Bio

I am a double board-certified physician in Internal Medicine and Allergy, specializing in remote healthcare as a virtualist. With a passion for AI technology and expertise in tropical medicine, I combine cutting-edge solutions with a deep understanding of patient needs. I am driven by a desire to learn about people's lives and cultures, aiming to build trust and provide the best possible care to my patients, regardless of their location.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
