First thing you want to look for from urgent care San Jose is the presence of a physician or the medical staff. This might seem like a give to you, but many urgent care facilities have a physician associated with the facility but who may not actually come in but a few times a week.
Whilst seeing a PA or a registered nurse is acceptable for minor things, if you have a severe issue, you want to ensure that there is a doctor available to treat you. You can find more information about urgent care San Jose facilities at http://urgentcaresanjose.org.
