First, congrats on finishing your EMT program. Try CARE and Schaefer. You may have to start out running IFT's first before you're placed on a 911 rig, but those are the other big "animals" in the LA County. Also, now that you are finished with EMT school don't let your books get dusty. Keep studying, look for other reference materials, and learn as much as you can from the job, especially from those that have a passion for the field. Always always ask A LOT of questions too. I assume you may want to eventually become a FF/PM. Be the best you can be at both firefighting and EMS. One more thing, be humble, and make a good name for yourself. You'll find that this industry is actually a small world. Someone you'll have contact with may be on your oral board someday for a department. With that said, keep your rig clean, your boots shined, your shirt tucked in, and walk proudly. Remember, YOU chose this field. Most importantly, treat every patient with dignity and respect, regardless of their situation. Good luck to you, I hoped this helps.
