Erin,
Welcome,, sorry for your husband's diagnosis but you will find a wealth of knowledge and personal experiences on this site.
I don't remember how long I waited ( about 6 years ago now),,, to hear from them but I did talk you Dr Slattery and he was wonderful. Very knowledgeable and informative and helpful. I didn't go out there, for very personal reasons unrelated to them,,, but he even called me about a year later to see how I was doing. He had agreed that watch and wait for a year was prudent in my situation. I eventually had translab surgery in 2011...
I would think perhaps you will hear from him tomorrow maybe, they may even have someone call to set up a time for him to call you, even in the evening,, they are very professional. If you talked to an assistant already, you know they received your info so I am confident they will contact you.
Try to make a list of questions you would like answered and be prepared to talk to him. I'm sure you will be pleased when you do hear from him.
Let us know,
Jane
