I want to thank Dr Siglar and his team for being very professional and kind. He is very knowledgeable and is very interested in the health and well-being of his patient. I couldn't have asked for a better group of people to help me on my journey to being a healthier,happier person. Thank you and may God continue to bless you Dr Siglar.
Dr. Usala is one of the best Doctors I have. He is very thorough and knowledgeable. I have been going to him for almost a year and he pinpointed my diagnosis on the first visit just by my symptoms and when my labs came back he was right on the money. Unfortunately due to my diagnosis there isnโt much he can due for my symptoms, but that hasnโt stopped him from trying. His staff is just as awesome as he is especially his nursing staff she brings a smile to my face every visit! His students have been also knowledgeable enough as you can expect a resident student to be!!!
Dr. Sigler is the best! He is caring, explains everything thoroughly, very kind and has helped me many times. He listens and responds so that I can understand. He is very knowledgeable about everything in the upper part of your body and also lower. I am so grateful that he is my doctor.
Dr. Sigler is a great pulmonologist. He explains things clearly and answers any questions I have and always treats me with respect. His staff is also respectful.
