He was very pleasant and thorough. He requested recent bloodwork done by my primary and called to discuss it with me as soon as he received it. He also told me to schedule a brain mri and to contact his officeas soon as I had a date in order to schedule an appointment for follow up. Also, his staff was very pleasant and his office had a very relaxing atmosphere. He made sure to look at the whole me and other problems I might have and not just focus on the reason I was there to see him..
