Legal Mind Meets Luxury Real Estate: Martha Mosier Named President of Pacific Sotheby’s International Realty
In a move that reflects both the prestige of its brand and the evolving landscape of luxury real estate, Pacific Sotheby’s International Realty has appointed seasoned executive and legal strategist Martha Mosier as its new president. The announcement, made Monday, signals a new chapter for one of the largest Sotheby’s International Realty franchises in the world.
Mosier, who brings with her an impressive dual pedigree in law and real estate leadership, is no stranger to the Southern California property scene. She previously served as president and general counsel at Berkshire Hathaway HomeServices California Properties, where she was a driving force behind operational excellence and strategic growth for over 15 years.
Now, she’s taking the helm at Pacific Sotheby’s with a vision that bridges tradition and transformation.
A President with a Purpose
“It is a privilege to join Pacific Sotheby’s International Realty and the iconic Sotheby’s International Realty brand,” said Mosier. “Our industry is rapidly changing and generating new opportunities for luxury advisors. I am excited to play a part in leading this remarkable enterprise to further success.”
Her statement underscores a key truth about today’s real estate world: luxury no longer relies solely on price points and aesthetics. It’s about experience, adaptability, and trust areas where Mosier has built a strong reputation.
A Legal Edge in a Shifting Industry
Mosier’s legal background gives her a unique advantage. As regulatory scrutiny increases and the real estate sector undergoes seismic shifts from commission lawsuits to evolving digital platforms Mosier’s expertise in compliance, risk management, and strategic governance will be critical.
“She brings a sophisticated understanding of the regulatory environment and a track record of leading through change,” said Russ Anderson, CEO of Pacific Sotheby’s International Realty. “Her exceptionally deep experience along with our aligned values make her the ideal choice.”
A Brand Reinventing Itself for the Future
With more than 600 real estate professionals across 18 offices in San Diego and Orange counties, Pacific Sotheby’s International Realty is poised to grow not just in scale, but in substance. The brand is part of Peerage Realty Partners, a powerhouse network of Sotheby’s International Realty affiliates across North America.
“Martha Mosier is representative of the talent and experience that will continue to lead us forward,” said Tara Brown, CEO of Peerage Realty Partners. “At Peerage, we’re focused on creating value and delivering an elevated experience for our advisors and customers.”
More Than a Leader: A Community Champion
Mosier’s leadership extends beyond boardrooms and brokerage offices. She’s been recognized as one of San Diego’s Top Five Women of Influence by the American Heart Association, reflecting her commitment to community impact.
As she steps into her new role, industry watchers see not just a seasoned executive at the helm but a trailblazer helping to redefine what leadership in luxury real estate looks like.
Pacific Sotheby’s International Realty, already a leader in Southern California, may now find itself a step ahead of the curve, thanks to a president who understands both the letter of the law and the language of luxury.
