It's interesting. My freshman year was the Biondi/interim year with Pestello taking over at the beginning of my soph year. I can tell you that immediately I, along with other students, took to Pestello. He was present walking around campus and really seemed to engage with the students as opposed to Biondi riding around in his golf cart with rumors of a tanning bed in his house. The clocktower protest in my mind put a fairly brand new president (a couple months) into a tough predicament. S2 is a bad situation, but I think more concerning, Pestello is putting SLU into a bad place financially. I remember there were some transparency concerns with the budget when I was there and it only takes a google search to see there were concerns over the budget during his tenure at Le Moyne. SLU decided to build two new, albeit beautiful, dorms. Now don't get me wrong, new dorms are important to attract freshmen students. I lived in Clemens and GFO and they weren't the best. But, SLU "surprisingly" found themselves in the red and had to turn to cutting a number of jobs and discontinuing the secondary ed department (a profession that embodies the Jesuit values and mission) along with other cuts. Probably the most worrying aspect about the new dorm situation to me is that these dorms are named Spring Hall and Grand Hall. It sounds like they (Pestello) couldn't find donors to support the new build. Maybe the donors wanted to be anonymous, but I don't know if I believe that. Biondi had to come back because fundraising was abysmal. I was talking with an administrator at my current school (I go to med school at another Jesuit university) and he mentioned something about a new building when they find the donor support to match the school input. To me that makes sense, its banana land to do otherwise.
Side note: I also think the rebranding process was a gigantic waste of time, effort, and money.
