Doctor for ADHD treatment

My partner and I recently moved to Houston from Montana. We are both on stimulants for ADHD and need to find a new doctor(s) to continue receiving our meds. I saw a psychiatrist a few weeks ago, and without any heads up, they asked me to do a drug test on my way out. I told them Montana has recreational marijuana, so it will come back positive. They told me not to worry, but when I received the bill it clearly says they tested for THC. We travel to states with recreational fairly regularly.

All of this to ask: Any recommendations for a doctor who won’t test for THC? Test me for anything else; test me to make sure I’m taking my meds & not diverting them; but given the regulatory environment in Texas surrounding other medical treatments, I’m not interested in anyone here having a record of my THC use or non-use on file. We’re in NW Houston but are willing to travel for this—Austin, Dallas, etc., will work if that’s where we need to go.
