Dr. Christopher Y. Lau, MD

Across Union Square’s busy sidewalks, an internist anchors primary care for adults. Dr. Christopher Y. Lau, MD operates from 10 Union Sq E #3g, a practical base in the neighborhood’s medical cluster. The practice belongs to a larger set of inner-city clinics that treat routine exams, mild illnesses, and preventive screenings under one roof.

Inside this quiet office, they handle full-spectrum internal medicine: annual physicals, chronic-condition checks, and acute-care visits when symptoms appear. Travel medicine and vaccine updates sit alongside blood-work coordination and medication tune-ups. For walk-ins needing a restroom or a quick temperature check, the space accommodates common but necessary stops.

To reach the office, call (212) 844-8100 during standard hours; an after-hours line handles urgent messages. The lobby clock usually ticks faster than the wait, yet the schedule stays predictable enough for planning around midtown traffic.
