Hi Lisa, Dr Titus Duncan and his staff are awesome. The time between the seminar and surgery was about 6 weeks. Dr Duncan does the seminars. I was seen by another doctor for the first visit. And Dr Duncan did my surgery.( he can be seen every thursday morning on channel 5news) You will learn this at the seminar. I had to get clearences from a cardiologist, pulmanary dr, referring doctor. I had to have physical, ekg, stress test. All this will have to be done before they will even make an appointment with you. It seems like a lot but it was worth it. I recommend when you find out if your insurance will pay. Go ahead and start making your appointment w/these doctors. Good luck and if you decided to go w/Peachtree Baricatric I think you will be very happy.
