I consulted with Dr. Ilgenfritz for a second opinion prior to undergoing 4 vein surgeries suggested by another physician. I am sure glad I did. He explained my condition and how things work very well and I was able to make far better decisions that I would have been able to make otherwise. I felt very comfortable with his suggestions. I was also impressed with the ease of getting in to see him and the efficiency and professionalism of his staff. Thank you Dr. Ilgenfritz!
