I know of a great Cham vet in texas, but it is in north Richalnd hills which is about a 4 hour drive from houston maybe even 5. The number is (817)788-2525.
He actually has pics up of some of the chams he has treated and owned in the office!!! There is also a female that practices with him. She isnt as experienced with chams, so If you do use him make sure to request the appointment with him not Dr. Gwen
