Everyone very friendly and professional. All questions answered, that made me comfortable with my procedure.
The DHAT facility was very clean and all of the staff was friendly. Cecelia helped me and she was very friendly and thorough. She even brought me a warm blanket. Nate was the nurse anesthetist. He explained everything thoroughly and he and Dr. Maddala made me feel safe and comfortable . I would recommend Dr Maddala and DHAT anytime.
Diagnosed in my 70’s with IBS Dr Maddala has been the light of my life and treatment. I thank God that I found her. She is a very kind, caring and knowledgeable doctor who understands the difficulties of living with IBS. She always seems to have a plan for my illness which I now finally understand is lifelong. Unlike many other doctors who have treated me over the years she ALWAYS makes time for me in every appointment to tell my evolving story. I cannot recommend her more highly!
Great practice! Friendly, professional and kind. Highly recommend!
Dr. Maddala is so wonderful. She is kind and very attentive. She goes the extra mile to make sure you get the best care. I searched for another GI Dr. after my previous GI Dr. didn’t really help me and I’m so happy the Lord led me to her. I suffer from terrible GI issues, bloating, gas, etc. I’m just grateful Dr. Maddala saw my concerns and desperation and took the necessary steps to help me. I recommend her highly. 🙏😊♥️
Dr Madalla is an amazing specialist she is kind compassionate and excellent in the O,R,
Great customer service they very nice they really take care of you
OMG! How in the world could this facility/organization be any better? I don’t know- and I’m a nurse! Organized. Clean. Orderly. Attentive. Accurate. Fabulous staff. Terrific Dr. Kind. Gentle. Timely. I even noticed there was a “time out” before my procedure. Many may not know this is an industry standard of safety. I also know that is not consistently done everywhere. So…Bravo! Job well done.
Dr. Maddala and team were great. From the beginning to the end, they were on time, very explanatory, and made us comfortable.
Dr. Maddala is the best! She and her staff are very kind, thorough and attentive. I highly recommend her.
Cannot say enough about DHAT Allen. All the pre work with scheduling, benefits checks to the day of and services onsite. Karen, Karen and April, Dr. Maddala, and all other staff made me feel at ease and in the loop of all things happening. Amazing experience.
Dr Maddala has been my physician for my colonoscopy for many years. She is the consummate professional and I totally trust her for my care.
Her staff is especially efficient, friendly and make the patients feel comfortable before their procedure. I especially appreciated Cecilia, who was the nurse in charge of my care during this visit. Great bedside manner and she made me feel comfortable and provided excellent care.

I was in good hands with Dr Maddal during my procedure. After my procedure I didn’t have any discomfort and I owe it to the great staff that Dr Maddala had. Thank you Dr Maddala.
Took very good care of my needs.
I didn't have any problems with the procedure.
Dr. Maddala, staff, and the super sweet nurse that prepped me for the procedure to the wonderful anesthesiologist, everything and everyone is top notch! I had a terrible headache when I arrived and my wonderful nurse was very compassionate and patient with me. Exceptional people right here!
Dr Maddala is really great, would recommend her to anyone. The facility and other staff were also excellent.
