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

Whitney (nurse) was wonderful to schedule this time sensitive matter concerning my home health recertification especially considering the DOL rules that required my home health nurse to be present during my telephone appointment . Dr. Sigler, even though he had an emergency at the hospital on the day of my appointment, did not cancel or reschedule the appointment. Instead he stayed late and ensured that my recertification was done before the deadline. That is service beyond my expectations and is truly appreciated. Thank you very much Dr. Sigler and team.\r\nDon St.Charles

Met with Maria Khouri, and she asked a battery of questions. One of which, "Anything specific you need to discuss with your Dr. today?" The information to the questions evidently did not get to Dr.Sigler, because he was in and out so quickly that felt the battery of questions she had for me was only for training purposes.
