The University of Tulsa is a good school with high standing. Of the schools that make up the university, I can speak of the ENS and A&S schools, which both had a very good and helpful counseling staff. I will say the university made the switch between colleges very easy, and this year has been extremely successful.
One issue I had with The University of Tulsa was that some of the professors organized their curriculum poorly so that study was difficult, and learning became very unintuitive or stressful in some classes. Less of this happened in the Arts and Science college, but it's still something to look out for.
The other issue I ran into was with getting transcripts and other official documents for outside scholarships. Deadlines were a real struggle to organize at times, and some services do not have very clear instructions.
All in all, a good school with few problems!
