Dr Toomey was great! Very friendly, professional and is very knowledgeable. He is efficient but never rushes you and truly listens to your concerns.

It was a great appointment. Totally put me at ease (until he mentioned the spinal block) but I’m past that now. Looking forward to my surgery and recovery
