    Dr Sigler has been my doctor for many years and i honestly believe I would not be here for the superior medical care that he and his team has provided to me over the years. I was In really bad shape when I started seeing him and he has got me back to a very good quality of life that I didn’t think was possible, he listens to you and takes all the time needed for you, never is in a hurry, his nurse Whitney is absolutely a God send, she has always worked with me to make sure everything was done that I needed and more, she is extremely busy in her new job with the doctor but she still will take time to do whatever is needed, she makes you feel like your her special patient but every patient feels the same way, she is just outstanding and has been from day one, all the other team members are excellent also, the Doctor and Whitney just run a top notch operation, they actually spoil you and you realize that when your seeking medical care for other things at other medical facilities and almost always becomes some kind of struggle to get thru it, I’m not sure I can say I enjoy going to the doctor but I can say I do not mind when it’s Dr Sigler and his staff. I’m proud to be associated with them. Dan Fountain Amarillo, Tx
