    In my almost seven decades of living, I've seen a lot of doctors, especially in the past eight years where I've been treated for cancer, but I will say Dr. Gilbert Daniels is such a shining example of how to do it right, how to be very well prepared for the appointment, how to communicate clearly and patiently during the appointment, and how to come up with some excellent plans for going forward. I am almost overwhelmed at how good my experience was with Dr. Daniels. I don't really want to have to see an endocrinologist on a recurring basis, but if I do, it will definitely be Dr. Daniels.
