Very long period to wait almost 3 hours plus the female worker were gossiping and laughing out loud and the wrost is the window they see you standing there and they don't wont open it to greet you or acknowlege if you.need and assistance and your there standing like an idiot. But the worst part of the visit is when dr. Grannum is finish talking with you and he recommends his assiant to complete the apointment surgery process they put you in a room where they have big tub awares and it looks more like a storage room than a glaucoma office for clients. Never less when a doctor recommends surgery without looking at any if your pass medical retina history that sort of worries me. Yes he is a graduate from yale but we are human and when we rush for a quick buck mistake can and will happen and he just didnt convience me enough that there weren't any other options for my glaucoma disease which i have researched and found could benefit me better.
