Through my own experiences, Marisol makes navigating through today's healthcare web an easy and palatable user experience. Yes - doctors and associates like Dr. Badr and Marisol still exist, though challenging to find, you can stop looking when you land on the Dr. Adnan Badr tile.

"Very proffessional, truly well earned reputation for best in Collin County"

Not only is he an outstanding physician, but his medical assistant, Marisol, is the best I have ever encountered in any medical facility. They are a competent, professional, and caring medical team who go above and beyond to help me when I am ill. If you need a gastroenterologist, this is who you want to call."
"I have been seeing dr. Badr for years and he has the best bedside manner of any GI doctor I've ever seen. He's compassionate, considerate, and is so understanding. Marisol who works for him is also just as kind and considerate as he is and will do anything to help you. I by far highly recommend their office if you have any need for a GI doctor. They will indeed get to the root of your problems and make you feel better ."
"Initially, the office at DHAT took additional time to schedule me an appointment due to internal polices for releasing paperwork. It took a week just to schedule the virtual appointment. For someone with chronic and sever pains who has been rejected by all other non-GI doctors stating I need a GI doc to look at me, every day feels like a lifetime to wait. First impressions of Dr. Badr were great. He is very knowledgeable in his field and I look forward to working with him further.
