A new standard in collaborative estate agency.

Because we believe the most important thing in any property transaction isn’t the property — it’s the person navigating it.

Chris Casey-Kon, Founder and Director

Born and raised in Maida Vale, Chris Casey-Kon is a seasoned property expert with over fifteen years of real estate experience across London. Before launching CORE in 2022, Chris held senior roles at a long-established international firm and later became a temporary partner at a boutique agency, where he deepened his belief that estate agency could—and should—be done differently. Frustrated by corporate systems that treated clients as numbers, Chris returned to his home turf in Queen’s Park to build an agency with care and creativity at its core. Today, CORE is one of the most respected independent agencies in West and North West London—and a proud sponsor of local schools, including Chris’s former primary, St. Saviour’s.

Holly Pearson, Lead Property Strategist

With over seven years’ experience spanning the quiet grace of the Cheshire countryside and the sharp tempo of London’s most competitive postcodes, Holly brings a rare dual perspective and instinct to every instruction. She spent the early part of her career generating cross-branch success within one of the capital’s fastest-growing agencies, quickly establishing herself as a force in South West London. But it was North West London—leafier, steadier, richer in community—where she found her deeper professional rhythm. Now based in West Hampstead and returning from a dynamic placement in Australia, Holly steps back into the London market with renewed energy and an unwavering commitment to people. Her strength lies in her investment, not just in the transaction, but in the lives, journeys, and intentions of those she works with.

“If you want an agency that genuinely cares and delivers, choose CORE.”
