Dont waist your time&money. They charged extra and refused to refund. Office manager was so rude. Procesure day i checked in 10:25am and it supposed to be start at 11:30. I waited there until 1:30pm. Receptionist said he showed up late and procedures pushed back. What? Really? Yes you're doctor but not a only doctor in Dallas. No responsibilities!Person who gave me ride needed to go back to work. Then i talked to manager and she cancelled it. After that office charged no show up fee ?? Really!!

He does not see patients by appointment. I spent three hours waiting to see him. he let me know, he stop seeing patients to do a procedure. He said he checked with his staff to see if anyone was upset. We signed in. We waited in the waiting room. later we are called and placed in an exam room. I was told he does not see patients in the exam room. After the exam room, I was taken to an office. He spent 5 minutes with me. HE HAS IT MADE IN Lancaster, Texas. Head them up. Move them out,

This doctor has a temporary office shared with others. No nurses working here, just two receptionists. I was taken to an office, not an exam room and waited while the doctor texted on his phone. He listened to me talk about my issue for about 2 minutes, then cut me off and said I had IBS. He wanted me to do a colonoscopy and another expensive procedure and pay a $500 convenience fee out of pocket to have both done at the same time. The whole place felt like a scam operation, really fly-by-night.

My husband went in to see Dr Mallat. He sat at his desk with a Lap Top in front of him. He never looked up at my husband at all. He ask what he needed and said ok. Never moved at all even when we told him what was going on with my husband. He finally got up, opened the door and said that he needed blood work done. When we got the bill from the lab that did the blood work it was for some genetic that was never ask if we wanted it done. The bill was $4,000. We didn't pay the bill & didn't go back.

I would HIGHLY recommend Dr. Mallat. We tell everyone we know about him, he saved my husbands life! I had taken him all over Texas to Gastroenterology Specialists for years, then we found Dr. Mallat. Needless to say he was critically ill by this time. It was a long slow process, it has been eight years now and he is as good as new! I thank God for pointing us in the right direction, and We thank Dr. Mallat from the bottom of our hearts for all he did.
