Hi, after reading your posting the other day I remembered that during my colon hydrotherapy training a decade ago we had a client who gave a very strong positive recommendation about a chiropractor there who embraced natural holistic healing.
I couldn't remember the doctors name, but I got in touch with one of my instructors and she was able to find it. I don't know if she is still practicing in Houston, but you may want to try to find
Dr. Jackie Martin D.C
100 Waugh Drive
Houston, TX 77007
713/861-0508 Listed as Dr Jacqueline Pearson Martin
or
Chinmai Connolly
2319 Huldy
Houston, TX 77019
713/523-3749
Chinmai was practicing colon hydrotherapy at the time, and may be able to refer you to someone else if Dr. Martin isn't available.
