Dr. Saema Tahir is a quadruple board-certified physician in Sleep Medicine, Pulmonary Disease, Critical Care, and Internal Medicine — one of a rare few to hold all four certifications. She practices on Park Avenue and serves as an Assistant Professor of Medicine at NYU Grossman School of Medicine. Dr. Tahir specializes in the full spectrum of sleep and pulmonary health: from insomnia, sleep apnea, and narcolepsy to COPD, asthma, chronic cough, and pulmonary hypertension. She has particular expertise in perimenopausal sleep disorders and the often-overlooked connection between disrupted sleep and symptoms like brain fog, fatigue, and emotional dysregulation in women. Her approach is thorough and individualized. First visits are unhurried deep-dives — reviewing full medical and sleep history, conducting physical exams, and ordering targeted diagnostics when needed, including home sleep studies. Follow-ups are thoughtfully adapted to each patient's progress, and are often available virtually for added convenience. Same-day and same-week appointments are frequently available — a rarity for a physician of her caliber. Dr. Tahir sees patients in English, in-person and online.
