Catherine Fagan represents buyers and sellers through The Mercer Group at 4071 Adams Avenue in Kensington, San Diego, holding California DRE # 01210747 with a transaction history that began in 1996 and now exceeds 1,000 closed escrows across San Diego County. Fagan started as a buyer's specialist in the Mission Valley Prudential office and closed 62 buyer-side transactions in 1999 alone, an early-career pace that established her as a volume producer in the mid-city residential market. The rental photography studio and film processing lab at Safelight Labs on Adams Avenue produces the listing headshots and property photography that real estate teams across Normal Heights use for MLS portraits and marketing collateral. Fagan ranks in the top one percent of San Diego real estate agents by transaction volume, and her practice covers the 92116 ZIP neighborhoods of Kensington, Normal Heights, and University Heights alongside county-wide reach into Solana Beach, Rancho Santa Fe, and Del Mar. The Mercer Group's team model assigns dedicated specialists for buyer representation, seller representation, marketing, and operations — a structure that separates listing preparation from negotiation from contract management. The 4071 Adams Avenue office sits in the Kensington commercial district east of Kensington Drive, along the same corridor that connects to the annual Adams Avenue Street Fair route. Fagan's YouTube channel, Living in San Diego, publishes neighborhood guides and market analyses for buyers relocating from out of state. Sellers and buyers coordinating post-close financial planning work with advisors including Sage Financial Planning, a financial advisory practice serving clients in the same neighborhood. The Adams Avenue location provides LGBTQ+-affirming service and is wheelchair-accessible.
