Ben McCoy and Sancia Obermueller are a two-agent partnership inside Pacific Sotheby's International Realty, pairing a global brand with hands-on, boutique representation across North San Diego County.
Ben McCoy and Sancia Obermueller have worked together since November 2019, approaching seven years as a partnership. They joined forces because clients are simply served better by two advisors than by one: two perspectives on pricing, two sets of eyes on a contract, and someone always reachable.
Together the business has grown significantly, but their larger goal has not changed: customer service, and educating clients through every step of selling and buying. They handle the parts of listings most teams delegate, from staging and preparing a home for sale, media days, contractors to personally attending showings, providing detailed feedback reports and escrow negotiations.

Sancia Obermueller is a Global Real Estate Advisor with Pacific Sotheby's International Realty in Carlsbad, serving Carlsbad, Oceanside, Encinitas, Fallbrook and Bonsall. She has worked in real estate since 2002 across sales, homeowner association management, mortgage financing and appraisal, including 17 years as an SRA Certified Real Estate Appraiser. That appraisal background is how she prices a home: comparable sales, condition and current buyer behavior, not guesswork.
Her analytical approach lets clients anticipate list price, marketing time and market conditions before they commit to a strategy. Sellers get a defensible number and a timeline; buyers get a clear read on whether an asking price holds up.
Sancia became a Realtor to help people through buying and selling in a caring, compassionate way. She listens first, to how a family lives and what they value, then works the process with communication, negotiation and industry knowledge that earns trust well past closing.
Raised between Seattle and Sydney, she grew up traveling with her grandparents, from the Great Wall of China as a child to two weeks in Italy with her 92-year-old grandmother. Architecture is what she photographs: aged stone, marble detail, romantic archways.
She served four years as Treasurer on the Board of Directors of the Fallbrook Food Pantry and continues to advocate for them. She volunteers regularly with local non-profits serving veterans, special needs adults and seniors, often alongside her three children.

Ben McCoy is a Global Real Estate Advisor and REALTOR with Pacific Sotheby's International Realty, bringing more than a decade of real estate experience and a strong background in construction, engineering, negotiation, and complex property matters to clients throughout San Diego County.
A San Diego native, Ben earned a Bachelor of Arts in Political Science from the University of California, Santa Barbara, with an academic emphasis in land-use law, land-use planning, environmental law, and environmental sciences. Prior to entering real estate in 2014, he spent nearly two decades in the forensic engineering and construction defect litigation industry, where he developed the attention to detail, contract knowledge, communication skills, and problem-solving ability that continue to shape his approach today.
Ben believes every client deserves exceptional service, thoughtful representation, and a sophisticated marketing strategy regardless of price point. He combines personalized guidance with the global reach and resources of Sotheby's International Realty, utilizing professional photography, video, aerial imagery, and digital marketing to position properties for maximum exposure and results.
Deeply committed to his community, Ben serves as Vice President of the Board of Directors for D'Vine Path, a North San Diego County nonprofit supporting adults with developmental and intellectual disabilities. He was also part of the team that helped facilitate the organization's 2021 purchase of its farm and vineyard campus.
Outside of real estate, Ben enjoys landscape photography, running, hiking, exploring local wineries, and spending time with his two daughters.

McCoy/Obermueller had a detailed marketing plan backed up by state-of-the-art technology. Most important to us however, was that they had a clear vision of the value of the house, the buyer profile they were looking for and what it would take to prepare the house for a successful showing. McCoy/Obermueller exceeded expectations from beginning to end on this sale.
From start to finish, Ben and Sancia demonstrated an exceptional blend of professionalism, integrity, and genuine care. Even in a challenging market, they went above and beyond to secure our purchase. From high quality media production to the smallest finishing touches, every detail was handled with precision and pride.
I had never experienced realtors to be so hands-on and so personal. That was a great help and a great relief! They kept me laughing vs. stressing through what’s become a rather complex process.
