Over the next 15 years, Dr. Carr and his assistant Joy Haskins, have trained over 1000 clinicians at his charitable, non-profit research foundation, PERF. Both with course work, and lecturing internationally over that time frame, the operating microscope, as well as his surgical and non-surgical retreatment advances, have become the standard in endodontics today. The entire specialty of endodontics was changed by these developments. A full CV, outlining these advances, lectures, and writings are at perfendo.org.

Starting in 1998 with his office manager Amy Taylor, Dr. Carr set out to revolutionize endodontic record keeping with the introduction of TDO:The Digital Office, a paperless administrative and clinical digital record in the hope of standardizing endodontic record-keeping and allowing fact-based and evidence-based outcomes research in endodontics. Today, TDO is the most widely used endodontic record-keeping software in the world. It has attracted top endodontic clinicians from over 30 countries and his clinical chat forums, tied to the software, allow truly unique collaborative communication between top clinicians on a daily basis. Over 1000 clinicians worldwide exchange views on over 20 cases per day on TDO-Clinical---raising the standard of care for countless patients and their doctors. Therefore, mentoring is a foundational principle in Dr. Carr's life and in his software enterprise.

In 2012, Dr.Carr invited 100 of his closest endodontic colleagues to a meeting in San Diego to discuss the formation of a new endodontic association. Disappointed with the commercial influence in our professional association, he asked the attendees to join him in the formation of the IAE (International Association of Endodontics) dedicated to commercial-free endodontic continuing education. Of the 100 attendees, 95 chose to form the association and the IAE was born. Today, it stands alone as the finest, non-commercial endodontic education in the world. International Academy of Endodontists.

Dr. Carr's consuming passion is clinical excellence, always striving for constant improvement, and mentoring others along the same path. Believing that clinical excellence, research, and giving back to one's specialty are the 3 most important things in having a complete career, Dr. Carr tries to live up to those goals every day.
