    I was very impressed with Marian and follow up. After I left the office, she reviewed some previous scans that I had and contacted me via my patient portal to point out a possible concern with one of the scans. Fortunately, I had been aware of the abnormality and it had been reviewed with the physician who ordered it in the past. I also was impressed that a blood test that she ordered came back the next day and even on a weekend day I got the results through my portal. It seemed like the comment was personal and not just a comment that comes up on the portal automatically if the results are normal.
