Who We Are

Mercer York is Bree Mercer and Keith York. Both native San Diegans, Bree and Keith are avid collectors of mid-century design, and live in architect-designed homes built in the 1950s.  Their love of architecture, and the county’s built environment, extends well back into the 19th century and forward to today’s great local architects, building designers, landscape architects, interior designers, furniture makers, artists, and crafts people.

Bree Mercer comes to Mercer York with over ten years of successful real estate experience. Selling as a REALTOR for Coldwell Banker, she knows the San Diego market like the back of her hand. Upon their purchase of the J.G. Wetherell Residence (circa 1955), Bree and her family opened up the home to its architect C.J. “Pat” Paderewski. That event reconnected a 98-year-old with one of his earliest career milestones, and added fuel to the renaissance of interest in San Diego’s post-war architects. Bree is passionate about design, especially when its roots are local. Talented well beyond her understanding of architecture and the local real estate market, Bree holds a degree in advertising, is an avid photographer and boy does she have some skills in the kitchen!

In addition to his work producing documentaries on local history and architecture, Keith York, has received accolades from San Diego city officials and preservationists for his restoration of Craig Ellwood’s only design in the county, as well as his thorough documentation of San Diego’s modernist architecture via modernsandiego.com. Keith and his family enjoy daily life in Ellwood’s Bobertz Residence (designed in 1953, built in 1955). Hosting tours, giving lectures and moderating forums on the topic of San Diego’s regional architectural heritage, Keith has become nearly synonymous with the topic. In his free time he is focused on writing about San Diego’s architectural history. Keith is experienced and knowledgeable about working with architects and contractors in restoration and remodeling projects, and is happy to help long-time owners refresh their living spaces, or help new buyers find creative ways to make a house their home.

Mercer York works for buyers and sellers in promoting and preserving great architecture here in San Diego. We would love the opportunity to connect with you, and to introduce you to an extensive network of San Diegans who revel in exploring quality design and life experiences.
