Looks like it's all a part of the big hospital network. (They all share the same main 5510 address.)

Full address of this Note is:

South Texas Bone & Joint Institute
5510B Presidio Parkway, Suite 2401
San Antonio, TX 78249

And it looks like the hospital is all 3 buildings:

- N = Hospital.
- S (where this Note is) = a big "Medical Office" building
--- Where I assume other surgeons/doctors are.
- SE = parking garage
--- 4 or 5 stories?
