Craig Kohler

Craig Kohler is the founder and CEO of ONVI, a Chicago-area oral health technology company building what he calls the operating system for oral health. A dentist for four decades on Chicago's North Shore, he spent 20-plus years recording procedures through surgical microscopes and noticed a pattern: patients who could actually see inside their own mouths started taking better care of their teeth. He turned that observation into a product line - the video-enabled Prophix brush, the LED-lit MOTSY Light manual brush, and the HIPAA-compliant ONView platform - backed by 39 patents and a $25 million Series A raised in August 2025.
