Dr Le Roux was my doc this most recent time in CT and I loved him! He was calm, patient and helped me achieve my twin babes that are happily growing inside me as I write this! (22+2wks)
He is usually quite responsive (sending replies from his iPhone and on weekends), as is his assistant Karin Schwenke, although there were a few times when I needed to drop them an extra line and whistle "yoo-whoo" through my emails ...and remind them that I was still waiting for some sort of response and it was contributing to extra and unnecessary angst for me so far away (I'm in Toronto, Canada), and with respect to such a big life decision. This usually rustled them up to respond more quickly !
I would try them again, but make mention that you're following-up as you've not heard back and I'm sure that will get things going.
Once your donor has been selected, your agency will advise your doc and things should start to happen.
Let me know if I can offer any further assistance and best of luck to you!
