San Antonio's allergy and immunology category holds 42 listings, spread across zips like 78258 with 8 and 78229 with 5. That spread means the field narrows fast once you pick a side of town, so start there instead of scrolling the whole set.

Every one of the 42 listings has a phone number, and 39 list a website, so most searches end with a call or a click rather than a dead end. None of these carry a Sponsored tag, since paid placement for this category hasn't started in San Antonio, so what you're browsing is the directory's default sort, not a promoted spot or a ranking. If you run one of these practices and a detail is missing or wrong, you can claim the listing and correct it yourself, which matters most in zips like 78224 where just 3 listings currently show up nearby.
