We recently worked with Linda Corcoran with the Squirrel Hill branch of Coldwell Banker.  Linda was wonderful to work with - she was very responsive; understood the market; helped us price our house for quick sale; and found a buyer in a week and a half.  She was also very helpful and reassuring during the inspections by the buyer and she even was kind enough to come over and unlock the door for me when I was accidently locked out - and she got there in 10 minutes!  I think Linda is a great realtor and you will get a knowledgeable, reasonable, understanding, and pleasant human being to work with if you hire her.
