J., I had my first 3D/4D done at my doctors office and was very disappointed. Then I went to place in Plano called first vu: http://www.firstvuimaging.com/
This place did such an amazing job! The room where the sono is done is roomy in case you want your mom or something to come along with you as well as the father of the child and they have a couch and chairs in the room where they can be comfortable as well. It had a peaceful, serene feel to the place. The staff was extremely friendly. I didn't feel rushed and I didn't have to wait over an hour like I did at the dr's office. I would go back to this place in a heartbeat if I ever have another child. My sesssion was suppossed to be 30 minutes but since no one was scheduled after me I was able to get a few extra minutes in since my son kept putting his hands over his face....I got a great shot of him sticking his tounge out...it is so dang cute! I truly did have a great experience at first vu!
