Dont go with Dr Jeffrey, he replies very promptly before the procedure, but after the procedure, it comes down gradually. If you are happy with the results, thats good, but if something goes wrong, he is not very helpful either. My expericen with him is horrible with less than 10% of the grafts growing in more than 2500. His responses cease or take lot longer when I ask him about it. I dont guess his staff is as cordial when you ask them about it.
