Growing Invisalign from 20 to 100 Cases

Grant Goodstein isn't a dentist — and that might be exactly why this episode is so refreshing. An American tech exec turned practice owner, Grant moved to London for love (a Hannah Montana-inspired trip to LA, a dating app, and a last-minute Vegas concert, if you can believe it) and ended up buying a mixed NHS practice in Fulham with his wife, Leah. 

What follows is a masterclass in what happens when someone with zero clinical background but serious business chops walks into a neighbourhood dental practice and starts asking, "What do patients actually want?" 

From GBT machines and AI phone systems to living wage accreditation and obsessing over Wi-Fi signal strength in the toilet, Grant's approach is equal parts Silicon Valley hustle and genuine community spirit.
