I know Tony and Melanie. I had a few private lessons with Tony and I had lunch with Melanie once when I was in NYC. My good friend used to teach at their studio.
They still own their studio (www.dancetimessquare.com).
Tony is an amazing teacher (quite expensive though), we had a lot of fun working with him. Melanie is a great person (I can't believe someone said that she is not a people's person!!). She is an artist and has a colorful personality but she is so nice. I remember how she was telling me that she just went to Barbara Walters house and stories about her exciting life, then she would ask us tons of questions about our (boring compared to hers) life! I was so happy to tell her that the movie Dance With Me inspired me to start latin (Tony and her did the choreographies for that movie, they are featured as well). It was a great moment for me!
