As OM pointed out, the Red Cross does offer basic first aid classes.

You might also go to a BSA Scout shop and pick up the first aid merit badge booklet. It has very good information.

You can also check with your local BSA council and see if any troops offer 1st Aid training and Wilderness First Aid training.
In the Dallas area, Troop 1000 out of Grand Prairie offered the WFA class 1-2 times a year. They do this as one of their service commitments to the community and to the Scouting community. It was taught by professionally trained first responders.

If there is an REI store close to you, they sometimes offer a basic 1st aid class.
