Currently, I am not attending CSUN's DPT program but I went here for undergrad and know a number of people currently in it.
CSUN in general is a commuter school, but despite this, still has a nice vibe to it. The campus gym is hands down one of the best fitness facilities around the area - if not, the best. I've known a handful of PT students there who work as personal trainers and group fitness instructors as their side hustle to get a break from the demands of PT school.
I don't know the in's and out's of the program, but there are respectable and knowledgable instructors that I am sure will give you an excellent education. They also boast a unique internship with the LA Dodgers!! It's selective, and I believe only one student gets this every year, but if you're interested in sports PT, and especially in baseball, then this is a no brainer for you. All my friends who are/were in the program are excelling and thriving.
The only 'con' I can think of is that there's no building specifically for PT students, I think it's shared with many other departments.. I think it's part of the engineering building? There still is one room with treatment tables, etc., though. Oh, another pro: you dissect real (not plastic, as is the case in some programs) cadavers.
Also... Northridge is within vicinity of lots of dope places. I'm obviously biased... and like others mentioned, it's cheap. Had I been accepted here last cycle, would've chose it in a heart beat!
