Barbers Three Plus is a long-established, locally owned barbershop in Corte Madera with roots dating to 1963. Recognized as the oldest barbershop in Marin, it has served the community for decades through classic barbering, including haircuts, traditional barber services, color, and related grooming work. The shop’s history is closely tied to Marin County, shaped by generations of ownership and longtime barber John Holm, who remained behind the chair until 2020 after 57 years of service. In 2024, Mariann became the fifth owner after 15 years working in the shop, carrying its legacy forward with a stewardship-minded approach that honors its heritage while introducing a refreshed midcentury modern feel.
