  • Another son, Brandon, has been employed by the Health and Human Services Commission's Medicaid eligibility division and now works in government relations for Harden Health Care.


  • Residence in Richmond valued at $848,180


  • Zerwas has filed bills that relate to his profession, including measures that would have expedited the credentials of doctors in managed care plans, put stricter rules in place for surgical technologists in operating rooms and required freestanding emergency clinics to become licensed. After he helped re-establish the bariatric surgery program at Memorial Hermann in Houston as the hospital's chief medical officer, he pushed for legislation to allow state employees to receive coverage for bariatric surgery. In an interview with The Texas Tribune, Zerwas said he's "somebody that lives in the health care world, and I have a specialty in particular that puts me into the area of health care that consumes more of the revenue, and that’s the hospital setting."

  • Zerwas has a long history in the medical profession and is frequently called on to carry bills and provide expertise on that topic in the Legislature. Many of his biggest campaign donors have deep ties to health care issues before the Legislature.
