I love Dr. Sacks. The two nurses I dealt with most often were Wendy and Venecia, both of whom were really nice. I also received Dr. Sacks's email address from Wendy at some point, and he is great about responding to questions. I emailed him most every day between my retrieval and transfer after I got updates from the nurses just to get his two cents, and he always responds. So don't hesitate to ask for his email address so that you can be in touch with him directly. He's very open to it. Most of your interactions, aside from appointments, will be with the nurses. They'll be the ones calling with updates from your blood work, embryo development, etc. And your monitoring appointments are short and very fast, so make sure you go in prepared with questions you might have. Dr. Sacks and the nurses will stop and give you answers, but they have a lot of patients to get to in the morning (as you'll see in the waiting room), so they don't automatically sit down for a 15 minute chat. But, they will answer any questions you have. And, if you want them to repeat how many follicles or whatever, just ask. They are very nice.
