What Our Patients Say


Dr. Payne is amazing!! Never have I met a doctor more interested in his patients. He takes time to get to know you, and your baby. I sincerely hope when it comes time for my second child that I still live near enough to use him.

My least favorite doctor visit is the well woman exam. Upon my visit Dr. Payne quickly identified fibroid tumors with a physical exam. He confirmed this with a sonogram and blood work. He personally called to tell me the results and spent time with me in person to answer all my questions related to my upcoming hystorectomy surgery. His office staff is professional and they are efficient. I would recommend Dr. Payne to anyone looking for a great OBGYN.

I had been seeing the same ObGyn for years. I finally decided to switch so I could deliver at Baylor. Dr. Littrell was highly recommened to me by several people, so I gave her a try. I really liked her. She answered all my questions and never made me feel rushed. I didn`t have to wait long at all compared to the other OBGyn I went to and the front office staff was really nice. I think Dr. Littrell is a great doctor, and I look forward to seeing her more. I would highly recommend her to anyone.

Dr. Littrell is by far the best doctor I have EVER seen! I completely trust her with my life as well as my childrens' lives. She is amazing, professional, friendly, caring, and goes out of her way for patient needs (as was my experience). She performed a VBAC for me with my twins and it could not have gone any smoother. I felt, the entire time, that I was safe and that if ANYTHING were to have gone wrong, she would have shifted to plan B...but she was strong, confident, and knew exactly what she was doing and was aware of everyone's health status the entire time. It was the best experience (my first delivery with a different doctor turned out to be miserable and completely frustrating...my previous OB doctor had poor communication and was not at all friendly or caring). Dr. Littrell was everything I could ever dream of in an OB doctor and I am going to miss seeing her as my primary physician during pregnancy. Dr. Littrell went out of her way to make me feel comfortable and to be there for me during the delivery of my twins...I can't say enough good things about her! Very knowledgeable, has superb commmunication, will definitely let you know when something needs to be addressed or if safety is a concern. RELIABLE!!!!! Super friendly and caring as well as thorough and OCD (in a good way...a way that allows you to feel like your developing baby(ies) are safe and well looked after). She is more than willing to answer any and all questions and does not make you feel silly for asking any questions. I LOVE HER, SHE IS AWESOME!!!

I have been a patient of Dr. Gunby's for almost 30 years and find him to be incredibly caring and considerate. I especially appreciate having face time with him in his office, prior to heading to the exam room where you have to undress for your examination. He never makes you feel rushed or apprehensive, and that makes all the difference in the world.

I have never met such a personable, caring, professional, and knowledgable doctor in my 35 years of nursing. Dr. Gunby is my lifeline in most aspects of my life. If it weren't for him, I'd probably be dead by now from cancer. I love him as a doctor and as a genuinely caring and professional man. I will never change doctors, and I hope he NEVER retires. I couldn't find another doctor as good as he is in this field.

Dr. Harper is fantastic. She is so sweet and caring. She genuinely cares about her patients. She sat down and talked with me for several minutes before our exam began. She got to know who I was and about my life as if she were a friend. I felt 100% comfortable during the exam, and I left very happy with finding such a wonderful physician.

Dr. Harper is by far the best gyno I have ever had. She introduced herself to me and we talked for about 20m before we got the appointment started. She answered any questions I had and and some I didn't ask. Also, I have never had a doctor call me personally with Pap results. She called to give me the all clear and asked how I was doing and if I had any questions. She has a wonderful bedside manner. I lucked out in finding her.
