Our Doctors

Dr. Gaurav Nigam is triple board-certified physician, in Sleep Medicine by the American Board of Sleep Medicine (ABSM), Family Practice by the American Board of Family medicine (ABFM) and the American Board of Obesity Medicine (ABOM).

Dr. Nigam specializes in the diagnosis and treatment of sleep disorders and has published over 30 peer reviewed papers in esteemed journals worldwide. His research interests in sleep medicine include central sleep apnea treatment, emergent central sleep apnea and parasomnias.

He is a true pioneer in the field of sleep research. During his fellowship at University of Michigan, Ann Arbor he published a sentinel paper in Journal of Clinical Sleep Medicine (JCSM) outlining a newly discovered sleep disorder which they termed "sleep related scratching".

Given his active contribution to the field in 2019, the American Academy of Sleep Medicine (AASM) Board of Directors selected him to the International Members Task Force committee to help grow the field in developing countries where there is a dearth of sleep medicine providers. In addition to sleep medicine Dr. Nigam also enjoys practicing hospital and emergency medicine.

When not practicing medicine Dr. Nigam loves promoting health and wellbeing by giving community lectures on plant-based diets. He also enjoys tennis, traveling, hiking, yoga and meditation.
