our team circle

Just like you, we built our own trusted team of experts & healthcare professionals to help you and the circle thrive together.



James "JT" Thomas, DDS, MS

Founder & Changemaker

The health:latch circle was born out of years of contributions from many providers and the struggles their patients faced. I credit the circle to all of these fearless men and women, and realizing we needed a community where everyone can come together and find help for oral restriction issues. This vision drove my every step and a deep hunger to overcome every obstacle to make this a reality.
