Dr Crawford qualified from Glasgow University in 2002 and immediately went into a multi-discipline GPT scheme with Edinburgh Dental Institute before heading to General Practice in Leeds in 2004. He worked there, primarily in the NHS for several years before heading further south and ending up for many years in a Private practice in Hitchin, Hertfordshire where he got his first experience with clear aligners. The arrival of his young family prompted a return to Scotland and a decade in Cowdenbeath practicing mixed nhs/private dentistry. In 2022 he moved to Broxburn Smile Centre to be a little closer to home and opted to begin providing Invisalign for the local community.
