Dr. Marks is a great doc. He takes the time to listen to all your concerns and explains everything he’s doing. He’s kind and so is his staff. I couldn’t ask for a better doctor.

My experience was better than I expected. The staff was great, the wait time was less than 15 minutes, the phlebotomist didn’t hurt while doing my blood work and the most important, Dr. Robert D.Marks was great. He listened to my concerns without talking over me and brushing my concerns away. He evaluated me and told me the next steps to take. He and his staff gave me great samples for my issues and it was a wonderful experience. I was very please and would refer anyone to Dr. Robert D. Marks. Choose him if you’re wanting a doctor to listen to you without interruptions, that say’s alot about his character. I give him and his staff five stars.
