Hey Tex, that is a tough situation. Yes, do to the state of the USA medical system (watch Southpark's Obesity episode regarding insurance) PT/Sports Med places multiple book several people at the same time. College and pros have their staff PT/ATCs or as you said, someone private. When I worked at a college we would have our athletes in the athletic treatment center one on one with an ATC or a student for up to 2 hours 5-6 days a week. I would tell them that they would never get this level of care anywhere else. Unfortunately, I do not know anyone in the Houston area. All my former contacts are in the Bay area and originated with people connected to Stanford Hospital in some way. When I went in for an emergency consult after I ruptured my groin I even saw a therapist doing a group rehab with everyday athletes on running rehab (they were marathon or those mud runner event types). After my SLAP repair and I was just getting PROM (it was one on one by a clinic I luck fully found close to work) and the therapist admitted that after the very initial beginning phases of PT, she did not really have the exp to get someone back to being highly active (hitting the weights hard). That it is niche market that a ATC/CSCS/Peronsal traniner could get into, but they are hard to find. She offered to give me clients but I managed and trained at corp fitness centers and did not have the time (although now I look back and wish it was something I explored, but to be honest, I was working enough and had my own training to priotize). I'll PM you the guy I knew in the Bay and maybe he will be aware of someone in your area that can help. PNF strenghting techniques by a therpist/ATC can really help but it very much a learned skill and for a strong guy like you would take someone to know what they are doing.
One thing you can look into is Active Release Technique in the Houston area.

I briefly looked at the providers and one that I saw was
https://houstonflex.com/. ART practitioners are generally chiros. Some will take insurance.
Other than that, dynmaic mobility,joint mobilization, and loaded stretching movements are def the way to go with maybe some static stretching thrown in at the end. You can also do PNF stretching tenchiques by yourself or get a friend.
