Dr Baisi has a particular interest in early intervention (Phase 1) orthodontics, indirect bonding techniques and digital orthodontics. His experience with clear aligner therapy began in 2003, when Invisalign was first introduced to Australia. He introduced Invisalign to The Ortho Practice that same year and is now a Diamond Invisalign Provider, having previously achieved Black Diamond status.

A passionate educator, Dr Baisi has held numerous teaching positions at the University of Sydney, lecturing and tutoring undergraduate and postgraduate dental and orthodontic students. He has also contributed extensively to the orthodontic profession, including serving as President of the Australian Society of Orthodontists (NSW Branch), Treasurer of the Australasian Orthodontic Board and Treasurer Elect of the Australian Society of Orthodontists (National), as well as holding board positions with both organisations.
