Nadia O'Mara

Year of Call: 2018

“I have instructed Nadia in complex cases, involving clients with learning difficulties and mental health issues and her work on these cases was excellent. She quickly established rapport with them and had great empathy that went beyond just doing her job. She is meticulous in her preparation and her written work is excellent”.

Solicitor Client

Nadia “not only understands the applicable law and policy with technical ease, but clearly grasps and understands the traumas suffered by our vulnerable client base … Her attention to detail was exceptional, and the legal and factual written arguments detailed in the skeleton argument was on a par with many experienced counsel we have instructed. I was particularly impressed with this considering her year of call.”

Solicitor Client
