PRM Houston Care Team | Endometriosis Excision Surgeons

Meet Your PRM Houston Care Team

Excision surgery,  not ablation, is the gold-standard treatment for endometriosis, but it takes a specific kind of surgical training to do it well. Our Houston team is built around that expertise, and it’s growing to give more patients in Texas access to it.

Here’s who’s currently treating patients in Houston, and who’s joining the team this year.
