About Dr. Sein A. Lynn, DDS
Dental offices in San Mateo range from large group practices to solo practitioners, but Dr. Sein A. Lynn, DDS keeps things simple with a single-dentist setup. The practice operates out of a South Norfolk Street location, just blocks from the downtown core but away from the busiest retail corridors. Early feedback suggests a quiet consistency: they hold a perfect 5.0 rating, though it’s based on just two reviews so far. The address—440 S Norfolk St—puts them near the border of the Beresford Park neighborhood, where residential streets meet the occasional professional office.
General dentistry forms the backbone of the practice, from routine cleanings to fillings and basic restorative work. Questions about services or appointments can be directed to (650) 548-1940, though specifics beyond standard dental offerings aren’t listed. For those mapping a visit, the Google map pins the office between a mix of mid-century homes and smaller commercial buildings, a pocket of the city that still feels more neighborhood than strip mall.
