She routinely acts as counsel in complex multi-party medical malpractice trials and appeals, with many appearances before the Superior Court of Justice and the Ontario Court of Appeal.

Daniela regularly acts as counsel in complex multi-party medical malpractice trials and appeals, having appeared before the Superior Court of Justice and the Ontario Court of Appeal. Her most recent courtroom accomplishments include a landmark victory in KB v Guhle (2025 ABKB), in which the Alberta Court of King’s Bench found a physician’s failure to meet the standard of care directly led to catastrophic injuries suffered by an 11-month-old patient. Other notable accomplishments include positive outcomes in Hasan v Trillium Health (2022 ONSC 3175) and Hemmings (litigation guardian of) v Peng (2022 OJ No 2674), both involving severely brain-injured plaintiffs; and recent appeal wins in Farej v Fellows (2022 ONCA 254) and Hasan v.
