Marc Geissberger,

Dr. Marc Geissberger taught at University of the Pacific for 30 years and ran Pacific’s prestigious complex and esthetic rehabilitation program. He is also a researcher and a published author in the areas of dental materials, contemporary fixed prosthodontics, and esthetic dentistry. 

Dr. Geissberger is also a researcher and a published author in the areas of dental materials, contemporary fixed prosthodontics, and esthetic dentistry. He serves as a consultant for many dental materials companies and helps guide product development.

During his 30 years in academia, he has maintained a private practice geared toward restorative dentistry with his brother and fellow Pacific alum Dr. Jeffrey Geissberger. He believes his continual involvement in providing patient care as well as a role in academia has given him a unique balance that allows him to blend the best of both worlds.

Dr. Geissberger is a member of the Catapult Speakers Bureau, has won several teaching awards, and has presented over 450 lectures and hands-on workshops to colleagues in the United States, Canada, Australia, New Zealand, China, Peru, Denmark, and Taiwan. He has co-authored and published numerous scientific papers and a textbook entitled Esthetic Dentistry in Clinical Practice for Wiley-Blackwell which is currently available in 4 languages (English, Spanish, Polish, and Turkish).

Dr. Geissberger earned a master’s degree in educational psychology in 1994 and has been a Certified Personal Trainer (CPT) with the National Academy of Sports Medicine since 2008. He completed his Fitness Nutrition Specialty (FNS) training in 2011.

Dr. Geissberger’s goal is to provide an educational experience for your group in a non-intimidating format that focuses on providing the clinician with the latest techniques and information that can be immediately incorporated into everyday practice. Presentations tend to be rich in information and Dr. Geissberger pledges to both entertain and educate simultaneously. All topics can be customized to the specific interests of the group and many topics can be paired with a hands-on workshop.

I find Dr. Geissberger is very in tune with most if not all of the challenges every dentist deals within the trenches
I learned something new. Or maybe the light just came on. I don't think I was doing a very good job with occlusal anatomy. Thank you for the explanation of high and low spots.
Speaker was very knowledgeable of the new products and how it can make your job easier. Like Flowable vs Injectable composite
The speaker had a strong command of the material presented.
Dr. Geissberger speaks clearly, and taught me things which I can incorporate in my practice. I recommend him as a speaker.
