Dr. Jesek is dedicated to lifelong learning and is an alumnus of the L.D. Pankey Institute for Advanced Dental Education and The Dawson Academy.

He has also earned the status of Master of the Academy of General Dentistry (MAGD). The Academy of General Dentistry (AGD) Master status is presented to dentists who are committed to pursuing professional excellence and providing the highest quality of dental care. In order to receive this distinction, Dr. Jesek completed over 1,100 hours of continuing dental education (400 of those hours in hands-on courses) and passed an exam equal in difficulty to board certification. As an AGD Master, Dr. Jesek has joined an elite group within the dental community who understand that great smiles and good oral health for their patients are the results of going above and beyond basic requirements. Mastership symbolizes excellence in the dental profession and a commitment to providing exceptional patient care.

“Becoming an AGD Master means a dentist has taken part in some of the most rigorous continuing dental education programs today,” said AGD President, Connie White, DDS. “Less than 2 percent of all dentists have achieved this designation and we are proud to honor Dr. Warren F. Jesek for his commitment and dedication to providing his patients with advanced and exceptional oral health care. He is exceeding industry requirements and paving a path of success, distinguishing himself professionally amongst his peers and exemplifying his allegiance to the dental community.”

In private practice since 1979, Dr. Jesek is the founder of Jesek Seminars Promoting Excellence in Dentistry and has served as a teaching assistant at the L.D. Pankey Institute, Vice President of the American Equilibration Society, and a Mentor on the Scientific Investigation Committee.
