Dr. Guess is a La Jolla native, and obtained his specialty training at the Department of Endodontics at the University of Pennsylvania, where he received the Louis I. Grossman Award as the top endodontic resident. He attended the University of the Pacific School of Dentistry where he obtained his DDS degree as valedictorian of his class.
Dr. Guess is Board Certified as a Diplomate of the American Board of Endodontics which represents Dr. Guess’ ongoing dedication to possessing the highest level of clinical skill and updated scientific knowledge to provide the best possible evidence-based care to his patients. Becoming Board Certified is a process that starts with first being Educationally Qualified by attending and completing an accredited Endodontic Speciality program. Next, the level of Board Eligible means an application has been submitted to commence the Certification process, and then finally the level of Board Certification is obtained by succeeding with the 3-part examination process: written exam, case presentation and an oral examination process. Less than 1/4 of practicing endodontists successfully complete the process and obtain the level of Board Certification which represents the pinnacle in educational and clinical capabilities in the specialty of Endodontics. Board Certification is not only about having the skill and knowledge to pass the exams at the time of certification, but it is a commitment to the specialty and to patients to stay on top of the advancements in endodontics due to the 10 year recertification cycle that is required of all Diplomates like Dr. Guess that became Board Eligible after 1996.
Training from the University of Pennsylvania has given Dr. Guess the tools, experience and knowledge to treat all types of endodontic cases both conventionally and surgically. Dr. Guess has shared these abilities by instructing at the bimonthly microendodontic and microsurgical continuing education courses at the University of Pennsylvania Center for Micro-Endodontics and he is currently an adjunct assistant professor at the University of Pennsylvania Department of Endodontics. For two years was on teaching staff for the General Practice Residency program at the Veterans Administration Heathcare System, San Diego, in La Jolla, CA.
