i had an appointment with dr della valle/mor/rush this june and had a very positive experience. the hospital floor is super well organized (it's color coded) and ran efficiently (i went from xrays to exam room to ct scan and back to exam room and waited less then 5 minutes in each place). the staff was nice and dr della valle seemed confident, willing, and able to answer all questions. i had heard several different people say very good things about him as a surgeon. his total number of resurfacings is not as much as some but he does seem to do enough to stay fresh (as far as i am concerned). after my visit with him was over, he introduced me to a 50+ male patient who was there for his 6 week post-op exam; the patient walked up and down the hall virtually limp free, said he felt great, and gave high praise to dr della valle ... that was enough for me ... my surgery date with him is 9/14 (5 weeks from today, if you were counting). feel free to ask me any question about him you want.
