- Brian
Dr. Marek was truly great to deal with. I have had some longstanding problems other doctors were not able to figure out and he took the time to listen to me and properly diagnose me. I feel normal again! He has a fantastic bedside manner and I have now recommended several family and friends to him who have been very pleased as well.
