Dr. Hammond showed me respect as a patient. Dr. Hammond is someone who every female would be comfortable with. This is my first male gynecologist and I wasn't sure if I would be comfortable talking to a male gynecologist. His conversation with me about my health issues showed me that he looked over my past appointments and tests results.
