    Dr. Guend explained everything I needed to know throughly. He explained options for my care including options and risks throughly. All questions answered for me and my husband. I would trust him completely to do the surgery I will most likely be doing. Completely satisfied with his recommendations. I left the visit feeling confident with what I would be doing when I return for further evaluation of my condition.
