Pat Caldwell

Pat Caldwell is a registered specialist in Endodontics and currently works in private practice on the Sunshine Coast, QLD. Maintaining close ties with the general dental community has allowed Pat to understand the challenges faced by dentists when performing endodontic procedures. This led to the development of the Endospot Skills School, which aims to help dentists develop the critical skills required to perform endodontics well. The need for new and better products to help facilitate these skills led to the formation of E3Endo with Mark O’Sullivan.


Mark O’Sullivan

Mark is a registered specialist in endodontics and currently works in private practice in Newcastle, NSW. Mark and his colleagues at his large specialist clinic have practised conservative restorative-based endodontics for over ten years. They were always looking for better, more efficient products. This led him and Pat Caldwell to partner with SS White giving his clinicians access to the best products available. A desire to provide these products to others to help simplify their working lives then lead to E3Endo.

Karen Crowell

Karen has been in the dental industry for twenty years, initially as a practice manager in private and corporate clinics. Before joining E3Endo as Endodontic Product Specialist, she managed sales for a multinational dental company. Karen focuses on customer service and achieving the best product fit for each clinic and practitioner. She joined E3Endo as she believed in the company's mission to improve the standard of endodontics while providing ongoing training and support for the clinicians we team with.
