Our Team

Generational Tradition

It all started when Brad Witherell was gifted a Civil War-era Henry rifle from his uncle as a teen, spurring his lifelong obsession with vintage firearms and American Old West antiques. In 1969 Brad founded Witherell’s as an antique appraiser and dealer.

In 1983, Brad held his first Western American auction in 1983 at a hotel ballroom in San Francisco. When the logistics of moving heavy items upstairs became complicated, he enlisted his 16-year-old son, Brian, to manage the process. Thus began a father and son’s decades-long journey into the world of collectors and the antiques they love, filled with fond memories and many blessings.

Team Members

  • Brian Witherell

    COO, Consignment Director

    Brian was raised in Healdsburg, California. He received his B.A. in Criminal Justice from Sonoma State University before joining his father in the family business. He claims there are parallels between the two fields, as they both require great detective skills to be successful. That’s what he loves about this business, the discovery of hidden treasures.

    When Brian is not working as the company’s Consignment Director he likes to golf, fly fish, run, hike and go camping with his family.

  • Susan Hambly


    Susan is a retired physician who grew up in New England and attended Boston University and Boston University Medical School. After a successful anesthesiology practice in NYC and California, she decided to change careers and transitioned to antiques and fine arts appraising and cataloguing.
