The waiting time is minimal. Pretty much I could schedule another appointment or run an errand after every visit of their practice. Dr. Segalene is very knowledgeable and explains every detail of my problem and exactly what to do at home. I like it because sometimes I forget things. Here I don't worry about that because she explains the logic of each step of the treatment. No wander she won the Patient Choice Award and was 2009 Top USA Doctor. They, also, have an office in Naperville which is more convenient for me.
