I had a negative impression of UH COP after reading many messages from this year and last year application cycles and talking with UH alumni (like staff being curt and rude, delayed answers, who-care-about-you attitude,
competitive rather than supportive environment amongst PharmD students, etc. ). However, my actual experience with UH COP has been quite pleasant. The staff answered my email questions promptly, no problem with phone calls, friendly atmosphere during the interview, etc. I've been impressed with the speed of the process despite their busy schedule (I applied around the begining or mid December by the way).
I'm sorry to hear that you had bad experience with them but I guess it depends on many factors (timing, which person you talked to, etc), so it might be best not to take it personally.
Good luck to all of us!!! Still 4 to 6 more years to go
