I didn't find the program sketchy, for me it was mostly cause I have been in Irvine for such a long time I wanted to try somewhere new. Since I was a UC Irvine undergrad (4 years) and then worked for the school for another 4 years, I have been in Irvine for 8 years. Though it is a nice city, I just wanted a change in environment. Since the tuition for USA San Marcos is same/close to Stanbridge, it didn't make the decision too hard.
I think the biggest drawback for me when it came to Stanbridge is the three days a week for class from 12 PM-9 PM. I rather have classes more spread out since I feel it is going to be exhausting. If I were to go to Stanbridge, I most likely would commute from home and traffic is horrendous for me 60 miles round trip and 3+ hrs on the road. After doing it for so many years, I just didn't have it in me to do it again.
As for the fieldwork, I heard it was all going to be in California, which I felt limited to the experience I could get. San Marcos offered more choices when it came to fieldwork and I am opened to go to another state.
Overall, Stanbridge is a good choice, but for me I wanted to try a new environment.
