At Leading Edge Seminars

We at Leading Edge Seminars offer skill-expanding instructional programs taught in a focused, one-on-one environment, providing dentists with dedicated attention and training from instructors. With convenient monthly evening classes and remote participation options, we enable dentists to expand their skill sets at a time and pace that works best for each individual and their practice.

Since 2008 we have had the pleasure to work with many dentists and dental professionals, helping them on their journey toward confidence and expanding their practices.

We look forward to working soon with you!
