• I was grateful that Dr Cahill met me in person to explain his expert opinion about the meningioma of the SSS and reassured me that it should not be an issue. After a recent fall it was part of trying to identify what caused the syncope event resulting in an ED adventure. I was not looking to have SX- just Understanding options and looking to improve the quality and safety of my life going forward (not miracles). I was most impressed when he said would assist to get resources to look into my neurological symptoms. I will be a pleasure to see him again for follow up in 2 years.

• The teleconference zoom appt. was scheduled much more quickly than I expected. Dr. Cahill was on time, warm and courteous personally, and clear in his explanations. There had been some confusion about what specialty I should be referred to and Dr. Cahill offered to "sort it out at our end" [redacted]. He and [redacted] explained procedures for a follow-up MRI. I could not have asked for more -- I am in good hands.
