Darien, CT |
I have developed a close and trusting relationship with Dr. Giesen. I feel that he is always available, that he cares, he follows up with a phone call if he is worried about me. I have experienced barriers to communication with other doctors and I feel that you really can be open and let Dr. Giesen know what's on your mind. Plus, he is very effective.
