Met with Dr. O Neil the first time in an emergency situation. He reviewed my case and explained options and surgery went as well as could be expected.He made recommendations for follow up treatment. I followed up with him 20momths later for a reoccurrence of the same disease and I felt he went above and beyond to review my case and offer advice.
