Contact Josh
Josh has been in the dental field for over 20 years. He started as co-owner of a full-service dental lab, where he gained valuable insight into all aspects of the laboratory process, from the bench to the boardroom.

After 12 years in the lab, he transitioned to sales as an Executive Implant Specialist for Dentsply Sirona Implants, where he learned to seamlessly integrate digital workflows into implant dentistry. His extensive implant training helped clinicians understand simplified digital techniques and highly technical implant surgeries. This experience led him to be the COO of a dental training company, creating protocols and processes to help clinicians and their teams maximize efficiencies and provide top tier patient experiences.
