Twenty-nine-year-old McConnell grabbed PRWeek's attention for her track record as PR manager of law firm Irwin Mitchell.
She secured 5,000 pieces of media coverage and her PR campaigns helped to attract 600 new business leads to the firm.
This year, she joined MK Things Happen to broaden her experience beyond the legal world. McConnell's proudest achievement has been her work on several high-profile campaigns including the successful Armed Forces Compensation Scheme.
She credits her success to her willingness to listen to criticism and improve herself based on her peers' advice.
