This is a great school!
In a way, Cal Lutheran is small and closely-knit, such that students and professors get to know each other well. This is excellent for getting individual attention to gain greater mastery of subjects. The members of the faculty will know your name.
In another way, the school seems big because of the surrounding areas. While Thousand Oaks is a safe and relatively quiet city, it is close to both Los Angeles and Santa Barbara for fun weekend getaways. Thus, you can feel at home there whether you're a big city kind of person or a smaller town kind of person, depending on where you decide to hang out. There's good hiking in the area too. The trail to the nearest waterfall is just a couple of miles away from the campus. Since CLU is near LA, they sometimes have famous guests. They recently had Albert Bandura, a great psychologist of our time (the one who did the Bobo doll experiment) come in and speak and the Emerson String Quartet, which has won Grammy Awards play in the chapel.
Physically, the school is clean and pretty. The architecture has lots of bricks and windows. They are constantly improving and expanding their facilities, and the standards for admissions rise each year. Also, they have many fun (and free) programs. Along with clubs, they have free leadership seminars, free bowling nights, and free career workshops. Parking permits are also free. Nearly all of the students are friendly and happy to be there.
