This the best taxi services that I ever received! I would not call or use any other taxi companies! The taxi came within minutes after I have called. I was worried that I would not get there on time to a meeting. Glen was very courteous and friendly, therefore my taxi ride was very pleasant. Glen took me to a meeting place that was way ahead of schedule. I highly recommend GMB Taxi of Waltham to my friends and co-workers. Thanks for such a professional taxi and courteous services that day!!
