Our OMM is pretty tough. The head instructor came from COMP as well as most of the table trainers. You get what you put in. We have some students who are OMM guru's and are doing the summer fryette course. We have a great cranial doc, and some great table trainers. Other students don't like that they have to treat another student for an entire semester when we haven't learned much yet. I think all schools have interested and non-interested students in OMM. I like it a lot and show up at lunch to learn more from the OMM doc during the student clinics at lunch.
Our 3rd and 4th years did great on the OMM section of the comlex so I guess they were well prepared.
There is no fellowship right now, though one was tried a year ago. I think it was too soon to figure out all the details. Because of CA history, there are still not a ton of DO's in SF.
I can't speak for the student who showed you around, but they may have an issue with the teacher , who knows? This is a good school, the prof's are great and the curriculum is tough. I don't know if any DO school can boast a better match (check the website for details. We have great rotations and I love the atmosphere here.
Of course thats just my opinion, I could be wrong.
