Great to the point and direct plan
Dr Dalman did not even touch on the main reason for this visit: severe venous insufficiency. I left in total disappointment and confusion about my further course of treatment. His way of communicating made me feel very uncomfortable and I didn’t get the chance to ask him about my venous insufficiency. I left very disappointed.

After my sonogram, Dr. Dalman reviewed the results in medical / technical terms.
