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.
