About

Bio

Pentuple board certified and recertified physician, expert in Internal Medicine, Pulmonary Medicine, Interventional Pulmonolgy, Sleep Medicine and Critical Care Medicine. I also completed a fellowship in nephrology. Used to work for TB control in NYC. Which would be my 6th fellowship. And the MPH requirements are very well known to me. I also love interventional pulmonology/bronchology.

Specialties
