The ONE ENDO® Story

Our journey in transforming the Endodontic field is not just a story of massive success; its a testament to our dedication to Endodontic excellence through doctor-owned private practice ownership and existing practice refreshes and transitions. We've revolutionized our approach through patented systems that allow doctors to own and operate a highly efficient and advanced practice, by blending personalized, pain-free treatments with advanced technology, and thereby redefining the dental experience for patients, doctors, entrepreneurial owners, and teams.


From the earliest days of One Endo in NY and CT, to offices all across the country stemming to LA, Drs. Dean Saccomanno and Nick Mastroianni shared a passion for paving their own way as Endodontists and modern endodontic entrepreneurs.  Driven by their commitment to their profession, the clinical outcomes of their patients, and the promise to deliver their clinical expertise and patient-first philosophy to the communities they serve, they successfully launched 9 practices in their first 3 years with 11 locations on the horizon for 2025. 


Together, we embrace the opportunity to learn, build, innovate and reimagine your future, without limitations on where the One Endo brand and influence could take hold and grow, creating massive success for your new practice or existing transitioned practice.  Beyond multiple practice ownership, Drs. Nick and Dean built the precise systems and business model to share the One Endo philosophy, reputable brand, proven systems, integrated technologies and solutions to support passionate Endo Entrepreneurs who see the vision and brave the path to  practice ownership, on their terms. The way it should be in the modern world.
