I used Dr. Marc at Concentra Urgent Care in Deer Park, TX. The previous reviewers are dead on the money. He is Awesome! So patient and caring. Such a great sense of humor to top it off. I never felt rushed or that he was in a hurry to move on to another patient. He took great care of me and gave me the advice and medication that I needed for my foot injury. Easily my favorite physician of all time. I wish I was a permanent local. Too bad I can't take him back to Pensacola, Fl with me. 5***** quality all the way.
