Southwest Clinical Trials

Houston's medical research institute listings cluster around two zip codes, 77030 and 77054, each holding eight entries, matching the Texas Medical Center corridor. The rest of the 55 listings spread thinner: 77008, 77027, 77040, 77058, and 77081 each hold two, and 77002 holds one. Start with those two dense zips for the widest set to compare before you call around.

Most entries have contact details filled in: 52 list a phone number and 48 list a website. That still leaves gaps, so call two or three institutes directly if the one you're eyeing is missing a number or link. SiteCity marks paid placements Sponsored, and none appear in this Houston category right now, so the order you see is unpromoted, plain directory listing. If you run one of these institutes and your own entry is missing a phone or website field, you can claim it and add the details yourself.
