[Highland Park] recommendation for a buyer's agent

Hello Neighbors, A relative of mine is coming to Pittsburgh in a week or so to look for a house to buy. He would like to use a buyer's agent and I told him I would use this list for recommendations. If you have any suggestions I would be most appreciative. Also, if you have any cautionary experiences, I would treat them the the utmost confidence and use the information to help guide in the selection process. Thank you very much, Joan Soulliere Farragut Street
